86th procedural mesh primitive. Wooden well-pail / mop-
bucket:
• body — closed cylindrical Y-axis cylinder via
addClosedCylinderY (collision-watertight)
• handle — thin horizontal box floating handleArc above
the rim, spanning at least bodyR×2 wide so its ends
align with the rim's outside edge
Without rotation the handle is a straight bar rather than
a true semicircle, but the bucket-with-handle silhouette
still reads correctly. handleArc parameter controls the
gap between rim and handle (small = handle touches rim;
larger = bucket-being-carried look).
Useful for well scenes (pairs with --gen-mesh-well),
servant-corridor mop scenes, kitchen prep stations,
homestead exteriors, dwarven mine shafts, ocean-ship
swabbing decks. Watertight under weld (verified 102
manifold edges, 0 boundary, 0 non-manifold).
85th procedural mesh primitive. Two-cylinder pot-bellied
stove silhouette:
• body — wide round Y-axis cylinder (the stove body that
holds the firebox)
• chimney — thin tall Y-axis cylinder rising from the top
of the body (the smoke vent)
Distinct from --gen-mesh-forge (square stone hearth + hood
+ chimney) and --gen-mesh-chimney (just the rectangular
shaft) — stove is the round-cylinder home / workshop
variant for cottages, smithies, alchemist labs, ranger
huts, dwarven mead-hall corner heaters.
Validates that chimneyR < bodyR so the silhouette always
reads as a wider-bottom-with-thinner-stack shape rather
than a flat tube.
Watertight under weld (verified 192 manifold edges, 0
boundary, 0 non-manifold).
84th procedural mesh primitive. Cylindrical scroll case /
map tube:
• body — thin tall Y-axis cylinder (the case proper)
• cap (optional) — shorter wider cylinder on top, set
capR=0 to skip for a bare stick / rolled-document spine
Distinct from --gen-mesh-chalice (foot + stem + bowl
silhouette) and --gen-mesh-lantern (4-tier base + globe +
neck + cap) — scroll case is the simplest 1-or-2-tier
"tube with lid" prop.
Useful for wizard-tower libraries, archive shelves, mage-
hut detail trim, scribe-table props, scout-courier waist
gear. Validates that capR >= bodyR so the lid always reads
as a proper top closure rather than a degenerate band.
Watertight under weld (verified 168 manifold edges, 0
boundary, 0 non-manifold). Two more clean uses of the
addClosedCylinderY helper.
83rd procedural mesh primitive. Tall standing floor torch:
• post — thin Y-axis cylinder rising from the floor
• bowl — wider shallow Y-axis cylinder (the fire bowl)
sitting on top of the post
Distinct from --gen-mesh-brazier (squat fire-bowl on a
short stem with a wide-base silhouette) — standing-torch
is the tall thin walking-height variant for lining
hallways, ceremonial paths, dungeon entries, palace
entrance walks, watch-station lighting.
Validates that postR < bowlR so the silhouette always
reads as the wider-bowl-on-thinner-pole shape.
Watertight under weld (verified 168 manifold edges, 0
boundary, 0 non-manifold). Two clean addClosedCylinderY
calls — pattern is now well-established for cylindrical
prop primitives.
82nd procedural mesh primitive. 3-tier ceremonial chalice:
• foot — wide flat base disc (the goblet's footprint on
the table)
• stem — thin tall connecting column (the holding-grip)
• bowl — wider shallow cup at the top
Validates that stemR < both footR and bowlR so the
silhouette always reads as the classic wide-narrow-wide
goblet shape rather than a degenerate cylinder stack.
Three more primitives that consume the addClosedCylinderY
helper this batch (lantern + chalice from the previous
two commits + this), pattern is now well-established.
Useful for chapel altars, treasure rooms, royal-court
banquet tables, ritual / cult scenes, dwarven mead halls,
fairy-tale storybook props. Watertight under weld
(verified 252 manifold edges, 0 boundary, 0 non-manifold).
Milestone: kArgRequired now reaches 420 documented flags.
81st procedural mesh primitive. Hand-held oil lantern via
4 stacked Y-axis cylinders:
• base — short narrow disc (the foot the lantern sits on)
• globe — wider taller cylinder (the glass enclosure
holding the wick)
• neck — narrow constriction above the globe (where the
cap meets the body)
• cap — wider short top (the metal hood that lets vent
smoke escape)
Distinct from --gen-mesh-candle (just wax + saucer) and
--gen-mesh-urn (4-tier pottery shape) — lantern's
wide-narrow-wide tier sequence reads as a glass-enclosed
wick under a metal hood.
Useful for night-watch stations, ranger camps, dwarven
mine tunnels, mausoleum interiors, vigil scenes,
witch-hut shelves. Watertight under weld (verified 336
manifold edges, 0 boundary, 0 non-manifold).
Two more handlers retire their open-coded Z-axis cylinder
geometry and call addClosedCylinderZ instead:
• --gen-mesh-bedroll: 60-line inline cylinder (side wall +
end-cap fans) → 1 helper call.
• --gen-mesh-archery-target: same 60-line block for the
target face → 1 helper call. The unused local pi
constant drops out as a side benefit.
Output bytes verified identical: bedroll surface area
1.6746 m² unchanged; archery-target 1.9504 m² unchanged.
Cylinder-helper rollout now complete on the Z-axis side:
woodpile (last batch) + bedroll + archery-target all use
addClosedCylinderZ. Future Z-axis tubes (e.g. mine-cart
axles, well-pail handles, scroll cases) opt in by
including cli_box_emitter.hpp.
80th procedural mesh primitive. Wax pillar candle:
• saucer (optional) — wider shallow disc base, the drip
catcher that sits on the table
• wax — thin tall pillar standing on the saucer (or
directly on the ground if saucerR=0)
Uses the addClosedCylinderY helper for both pieces — same
two-cylinder pattern as --gen-mesh-bird-bath but with a
much skinnier upper cylinder. The 81-line handler is
mostly arg parsing + validation; geometry is just two
helper calls.
Useful for chapels / shrines, vigil scenes, witch-hut
ritual surfaces, alchemist labs, séance tables, festival-
of-lights ground decoration. Set saucerR=0 for a plain
candle without the saucer (e.g. for stack-them-on-a-cake
contexts).
Watertight under weld (verified — wax + saucer are two
independent closed cylinders).
Milestone: now at 80 procedural mesh primitives.
Z-axis sibling of addClosedCylinderY: emits a watertight tube
lying horizontally along the Z axis, centered at (cx, cy) on
the XY plane and spanning z=z0..z=z1. Mirrors the Y helper's
side-wall + ±Z cap-fan layout.
Refactor --gen-mesh-woodpile to use the new helper. Its
addLog lambda collapses from 60 lines of inline cylinder
geometry to a 3-line wrapper:
auto addLog = [&](float cx, float cy) {
addClosedCylinderZ(wom, cx, cy, logR, -halfL, +halfL, sides);
};
Output bytes verified identical: woodpile surface area
3.3416 m² unchanged.
Establishes the helper for future Z-axis cylindrical
primitives — bedroll and archery-target (which currently
inline similar code) can adopt it next.
79th procedural mesh primitive. Vertical urn built from 4
stacked tiers using the new addClosedCylinderY helper:
• foot — wide short cylinder (the ground-meeting base)
• body — tall main cylinder (the storage volume)
• neck — narrow constriction
• lip — slightly wider rim cap
Each tier is an independent watertight Y-axis cylinder with
its own ±Y end caps; they're stacked vertically with each
sitting on the previous tier's top.
Useful for temple offerings, mausoleum interiors, kitchen
storage, alchemist labs, funerary scenes, witch-hut detail.
First handler to consume the new addClosedCylinderY helper —
demonstrates the pattern for future cylindrical primitives
(candle, lantern, scroll case, well-pail, etc.).
Watertight under weld (verified 432 manifold edges, 0
boundary, 0 non-manifold).
Hoist the local addYCylinder lambda from --gen-mesh-bird-bath
into cli_box_emitter.hpp as inline addClosedCylinderY(wom, R,
y0, y1, sides). Closed Y-axis cylinder (side wall + ±Y end
cap fans) — the standard watertight tube primitive.
bird-bath now reads as two helper calls:
addClosedCylinderY(wom, stemR, 0.0f, stemH, sides);
addClosedCylinderY(wom, basinR, stemH, stemH + basinH, sides);
vs the previous 60-line inline lambda. Output bytes verified
identical: bird-bath surface area 1.0788 m² unchanged.
Establishes the helper for future Y-axis cylindrical
primitives (urn, candle, lantern body, scroll case, well
pail, etc.) — they can stack tubes with one call each.
78th procedural mesh primitive. Long open-top wooden planter
with a visible soil-fill block:
• 5-piece basin construction (bottom slab + 4 perimeter
walls), same arrangement as --gen-mesh-water-trough
• soil block filling the inner cavity from floor up to
soilTopFrac × height (default 85%), slightly inset from
walls so it visually sits "inside" the wood
Distinct from --gen-mesh-water-trough (square basin without
a soil-fill block) — planter-box is the long elongated
garden variant. Useful for window sills, kitchen herb
gardens, balcony planters, monastery cloister-walk
container plants, market-stall produce display trays.
The 6 non-manifold edges (--info-mesh-stats) are at the
4-wall corners — same expected pattern as water-trough,
where the inner walls share corner positions with each
other.
Milestone: kArgRequired now reaches 411 documented flags.
Eighth themed mesh pack after camp / blacksmith / village /
temple / graveyard / garden / dock. Inn/tavern scene
emitting a 7-primitive watering-hole layout:
• house — the inn building
• chimney — above the kitchen hearth
• table — the common-room centerpiece
• bench — seating
• barrel — ale / cider stock
• bookshelf — back-wall record / register / library
• signpost — the inn-sign post out front
Together these form a minimum-viable tavern setup for any
roadside inn, town watering-hole, road-house mid-route stop.
Composite-pack catalogue: camp + blacksmith + village +
temple + graveyard + garden + dock + tavern = 8 themed mesh
packs. --list-packs surfaces 13 composites total
(including pre-existing zone/project starter packs).
77th procedural mesh primitive. Garden bird-bath:
• stem: thin Y-axis closed cylinder (the column)
• basin: wider shallow Y-axis closed cylinder on top
Both are full closed cylinders (side wall + ±Y cap fans) so
the model is a watertight solid. Local addYCylinder lambda
emits each tier — keeps the per-handler code self-contained
without forcing yet another module-level helper.
Distinct from --gen-mesh-fountain (basin + spout column,
larger water feature) — bird-bath is the small ornamental
garden version. Useful for monastery courtyards, druid
sanctuaries, noble-house pleasure gardens, sanctuary
clearings, ranger huts.
Watertight under weld (verified 192 manifold edges, 0
boundary, 0 non-manifold).
76th procedural mesh primitive. Classic 3-tier square
pedestal for statues / monuments / hero memorials:
• plinth — bottom block, plinthExtra wider per side than
the body (the foundation that meets the ground)
• body — tall central pedestal sitting on the plinth
(where the inscription would go)
• capital — small wider cap on top of the body (where
the statue's feet would rest)
Distinct from --gen-mesh-podium (stepped pyramid with
lectern at back) and --gen-mesh-altar (stacked round
discs) — this is the classic single-statue square
pedestal shape.
Useful for town-square monuments, hero-of-the-revolution
memorials, plaza centerpieces, mausoleum interiors,
saint-statue stands. Watertight under weld (verified 54
manifold edges, 0 boundary, 0 non-manifold).
Seventh themed mesh pack after camp / blacksmith / village /
temple / graveyard / garden. Harbor / dockyard scene
emitting a 7-primitive port-side layout:
• dock — the pier itself
• crate-stack — cargo waiting to be loaded
• barrel — sailor stash
• canopy — shade for the dockmaster's station
• bench — passenger waiting area
• signpost — port marker
• hitching-post — for tying up small boats / mounts
Together these form a recognizable harbor / dockside
pickup-and-drop area when arranged in a zone.
Composite-pack catalogue: camp + blacksmith + village +
temple + graveyard + garden + dock = 7 themed mesh packs.
75th procedural mesh primitive. Row of N stone pillars
evenly spaced along the X axis. Each pillar is a single
tall rectangular box optionally crowned by a slightly-wider
square cap (capExtra wider per side).
End pillars inset by pillarW so they sit at exactly the
±span/2 ends. Set capH=0 for bare un-crowned columns.
Useful for ruined temples, palace colonnades, dungeon
hallways, dwarven mead-hall arcades, ceremonial entry
walks. Distinct from --gen-mesh-pillar (single column) —
this is the regular-multi-column composite, the third
"scene" primitive after --gen-mesh-crate-stack and
--gen-mesh-gravel-pile.
Watertight under weld (verified 144 manifold edges, 0
boundary, 0 non-manifold). Default 4-pillar / 4 m / 2.5 m
spacing reads as a small temple front porch.
74th procedural mesh primitive. Long horizontal hitching
bar held up by N evenly-spaced vertical posts. Distinct
from --gen-mesh-hitching-post (just 2 posts + bar) — this
is the longer multi-post variant for taverns, stockyards,
racecourse parking, market days, festival hitching lines.
Posts auto-spaced from -L/2 to +L/2, inset by postW so the
end posts align with the rail tips. Bar spans the full
length on top of the post tier.
Watertight under weld (verified 90 manifold edges, 0
boundary, 0 non-manifold). Default 4-post / 4 m rail at
1.2 m mount height fits typical mount silhouettes.
Milestone: kArgRequired now reaches 400 documented flags.
Fifth themed mesh pack after camp / blacksmith / village /
temple. Cemetery scene emitting a 7-primitive burial yard:
• grave — filled plot mound
• tombstone — marker stone
• coffin — above-ground or open
• statue — mourning angel / patron deity
• stone-bench — for visitors and mourners
• gravel-pile — loose earth from a fresh dig
• cage — fence section / mausoleum gate
Together these form the standard town-edge burial yard
when arranged in a zone. Composite-pack catalogue now:
camp + blacksmith + village + temple + graveyard.
All 7 outputs validate clean. --list-packs surfaces 10
composite flags total (5 mesh packs + the pre-existing
zone/project starter packs).
73rd procedural mesh primitive. Open-top mining cart on
4 wheel boxes:
• bin: 5-piece basin construction (bottom slab + 4
perimeter walls), same arrangement as
--gen-mesh-water-trough
• wheels: 4 cube boxes at the corners, inset by
wheelInset and sitting on the ground (y from 0 to
2*wheelR)
• bin sits on top of the wheels at y = 2*wheelR
All axis-aligned — exercises every shared helper. Useful
for mines, dwarven forges, gnomish junk-yards, abandoned-
tunnel set dressing, salvage scenes.
Default 0.9 × 0.5 m bin with 0.08-radius wheels gives the
classic narrow-gauge ore-cart silhouette. The 4-wall basin
construction (verified via --info-mesh-stats: 6 non-manifold
edges at the wall corners — same as --gen-mesh-water-trough's
expected branchy edges) means the cart can hold collision-
visible ore inside if a content author drops in another
primitive.
Two related changes:
• --list-packs walks kArgRequired and surfaces every flag
matching --gen-*-pack (excluding --gen-mesh-* and
--gen-texture-* which are individual primitives). Sister
command to --list-primitives. Auto-tracks new packs as
they're added — no parallel registry.
• --gen-temple-pack composite — temple/shrine ritual hall
(altar + shrine + brazier + pillar + statue + portal +
podium). Fourth themed mesh pack after camp / blacksmith /
village.
list-packs now surfaces 9 composites including the pre-
existing zone-* / project-starter packs that match the
naming convention. All 7 temple-pack outputs validate clean.
72nd procedural mesh primitive. Long stone bench from 3
axis-aligned boxes:
• horizontal seat slab spanning the full length on top
• 2 vertical block supports near the ends, inset by
supportInset from each end so the seat slab overhangs
them slightly (the standard "seat rests on legs" look)
Distinct from --gen-mesh-bench (wooden 4-leg construction
with thinner pieces) — this is the heavier stone variant
for parks, temple courtyards, ruined cities, dwarven mead
halls, library-courtyard reading nooks.
Watertight under weld (verified 54 manifold edges, 0
boundary, 0 non-manifold). Default 2.0 m × 0.4 m bench at
0.45 m sit height reads at adult-human proportions.
Uses every shared helper added in recent batches —
new gen-mesh handlers now consistently land at ~50 lines
including parse + validate + geometry + finalization.
Third composite pack (after --gen-camp-pack and
--gen-blacksmith-pack), emitting a 7-primitive village-square
scene into <outDir>:
• house — main dwelling
• outhouse — privy beside it
• chimney — for the house roof piece
• hitching-post — at the hitching rail
• well — village square centerpiece
• signpost — pointing the way out of town
• haystack — from the nearby farm
Together these form a recognizable rural-village hub when
arranged in a zone. Uses the existing emitMeshPack helper —
the new pack is just an 8-line declarative table.
All 7 outputs validate clean (--validate-wom PASSED across
the board). Composite-pack catalogue now: camp + blacksmith
+ village.
71st procedural mesh primitive. Hash-distributed pile of
stone cubes in a roughly conical heap. Each stone gets:
• polar position (radial, theta) with sqrt(rand) on radial
so stones aren't bunched at center
• height limited by yMax = pileH * (1 - radial/baseR), so
larger / more numerous stones land near the base and
smaller ones perch on top — natural gravel-pile profile
• size in the 40-100% range of maxStoneSize
The second multi-box "scene" composite primitive (after
--gen-mesh-crate-stack), but using irregular hashed
placement instead of a regular N×M×K grid. Deterministic
from seed: re-running with same args reproduces the
identical pile.
Useful for mine entrances, construction sites, quarries,
ruined walls, abandoned-fort rubble, pirate-cove stash
mounds. Default 24 stones at 0.6 m base radius gives a
reasonable medium-pile.
Uses every shared helper introduced this batch (printWomWrote,
printWomMeshStats, setCenteredBoundsXZ, addFlatBox,
saveWomOrError, parseOpt*, stripExt).
Two more print-pattern extractions for the gen-mesh side:
• printWomWrote(base) — the "Wrote <base>.wom" success line
every handler emits at the start of its stat report. 71
sites collapsed.
• printWomMeshStats(wom) — the canonical final 2-line pair
"vertices : N" / "triangles : T" emitted at the end of
every standard primitive's stat report. 49 sites collapsed.
Output bytes verified identical: firepit and tent surface
area / vertex / triangle counts unchanged.
The one remaining open-coded "Wrote" line is in
--gen-mesh-textured which writes both a .wom and a .png in
the same line — different signature, left unchanged.
These complete the print-helper trio (printPngWrote on the
texture side, printWomWrote + printWomMeshStats on the mesh
side). New primitives now end with one helper call instead
of three printfs.
70th procedural mesh primitive. Round-faced archery target on
a 2-post stand:
• face: closed cylinder along the Z axis (flat ±Z caps face
the archer line, side wall is the rim) of radius faceR
centered at height postH
• stand: 2 vertical posts at the bottom, sized to reach
from ground to the bottom of the face, with a horizontal
cross-beam joining them just below the face for rigidity
Concentric scoring rings live in texture space, not geometry —
the cap discs are the natural canvas for a separate target-
ring texture (or use --gen-texture-rings / --gen-texture-
starburst on top).
Pairs naturally with --gen-mesh-training-dummy /
--gen-mesh-fence for sparring grounds, training yards,
militia drill squares, mid-summer fair scenes.
Watertight under weld (verified 198 manifold edges, 0
boundary, 0 non-manifold).
Two changes in one commit because they're co-designed:
• Extract emitMeshPack(outDir, packName, items) as a shared
helper that takes a vector of PackItem {flag, fn, leaf}
and runs each handler with a synthetic argv. Keeps the
"build a 2-element argv per sub-handler" wiring in one
place instead of copy-pasted per pack.
• Add --gen-blacksmith-pack on top: a smithy-themed
composite emitting forge + anvil + workbench +
water-trough + crate-stack + hitching-post into outDir.
The classic forge-floor layout in 6 .wom files.
Refactors --gen-camp-pack to use emitMeshPack (verified
unchanged: 6 .wom files still land in the camp dir).
Pattern is now established for future packs (--gen-village-
pack, --gen-temple-pack, --gen-dock-pack…) — each is just a
list of primitives in 8 lines of code.
69th procedural mesh primitive. Built from up to 3 axis-
aligned boxes:
• stone hearth: rectangular base spanning width × depth ×
baseH, where the smith's fire would sit
• hood: smaller smoke-collector box on top of the hearth,
inset by hoodInset on each side so it reads as the
chimney's flared base
• optional thin chimney rising from the hood — set
chimneyH=0 for an open-vented forge
Pairs naturally with --gen-mesh-anvil and
--gen-mesh-workbench for blacksmith/armorer/farrier scenes,
and with --gen-mesh-bench / --gen-mesh-crate-stack for
the storage corner of a smithy.
Watertight under weld (verified 54 manifold edges, 0
boundary, 0 non-manifold). Default 1.4×1.0×0.9 m hearth +
0.5 m hood + 1.2 m chimney reads as a normal village smithy.
68th procedural mesh primitive. Built from 3 axis-aligned
boxes:
• solid body slab spanning width × depth × (height-roofT)
• thin door slab on the +Z face (pushed slightly outward
so it visually sits on the wall — gives doorframe-like
relief without a real cutout)
• roof slab slightly larger than the body footprint and
sitting on top, controlled by roofOverhang
Distinct from --gen-mesh-house (multi-walled, peaked-roof
dwelling). An outhouse is the single-room privy / tool shed
variant — useful for villages, frontier outposts, small
farms, refuse-shed corners.
Watertight under weld (verified 54 manifold edges, 0
boundary, 0 non-manifold). First handler to use the new
setCenteredBoundsXZ helper from this batch.
Convenience composite command: emits a complete outdoor-camp
scene (tent + firepit + bedroll + canopy + woodpile +
haystack) into <outDir>/ as 6 .wom files in one invocation.
Internally builds a synthetic argv array per primitive and
calls each existing handler — so the camp pack always
matches the per-primitive defaults exactly. Users wanting
custom dimensions should call the individual --gen-mesh-*
commands.
Smoke tested:
• Creates outDir if needed
• All 6 .wom files validate clean (--validate-wom PASSED)
• Vertex / triangle counts match per-primitive defaults
(firepit 240/120, woodpile 324/288, etc.)
The first composite command in the editor — establishes the
pattern for future packs (--gen-village-pack, --gen-dock-pack,
etc.) by showing how synthetic argv arrays let one handler
delegate to many others without spawning subprocesses.
21 procedural mesh handlers used the same two-line bounds
stanza for primitives whose footprint is symmetric in X+Z
and rises from y=0:
wom.boundMin = glm::vec3(-halfX, 0, -halfZ);
wom.boundMax = glm::vec3( halfX, maxY, halfZ);
Hoist into cli_box_emitter.hpp as inline setCenteredBoundsXZ
(WoweeModel&, halfX, halfZ, maxY). Each call site collapses
to one line.
Output bytes verified identical: firepit bbox 1.200 × 0.200
× 1.200 unchanged, haystack bbox 1.200 × 0.900 × 1.200
unchanged. Asymmetric bounds (e.g. handlePodium with
different X and Z extents on the min/max lines) are
deliberately left untouched — the helper only matches the
common symmetric case.
67th procedural mesh primitive. Standard town/stable
hitching post:
• two vertical posts separated by `span`
• horizontal cross-bar at upper-post height (length =
span - postW so it tucks INSIDE the post inner faces,
matching real fence joinery)
• optional decorative caps on each post — set capH=0
for a bare working-yard post
All axis-aligned boxes, exercises every shared helper
(stripExt, initWomDefaults, addFlatBox,
finalizeAsSingleBatch, saveWomOrError). Watertight under
weld (verified 90 manifold edges, 0 boundary, 0
non-manifold).
Useful for stables, taverns with mount parking, town
squares, frontier outposts, ranger camps, post-and-rail
fence segments.
66th procedural mesh primitive. Combat training dummy from
axis-aligned boxes:
• vertical post from ground to baseH (the stand)
• cubic torso block stacked on top of the post
• horizontal cross-bar arms at upper-third torso height
spanning armSpan along the X axis
• optional head cube above the torso (set headSize=0
for a headless training-block style)
Pairs with --gen-mesh-anvil / --gen-mesh-workbench /
--gen-mesh-fence for sparring grounds, militia drill
squares, training yards, weapon-master compounds. Useful
for any "things-to-hit" set dressing where animated NPCs
would target a static prop.
Watertight under weld (verified 72 manifold edges, 0
boundary, 0 non-manifold). Default 1.0 m post + 0.4 m
torso + 0.18 m head reads at adult-human height.
65th procedural mesh primitive. Open-top rectangular basin
built from 5 axis-aligned boxes (uses every shared helper
from cli_box_emitter):
• bottom slab spanning full footprint at wallT thickness
• +X / -X side walls spanning full length
• +Z / -Z front/back walls spanning the inner length so
they tuck inside the side walls without overlap
Inner cavity (length-2*wallT × height-wallT × width-2*wallT)
is the open water/feed volume. Useful for stables, farmsteads,
taverns, stockyards, alchemist mixing basins.
Default 1.4 × 0.5 × 0.5 m is a reasonable horse-trough size;
configurable for smaller hand-basins or larger livestock
troughs.
64th procedural mesh primitive. A simple scout/sentry
watchpost from axis-aligned boxes:
• tall central pole rising from ground to postH
• square platform slab on top of the pole, wider than
the pole so it overhangs as the lookout deck
• 4 corner railing posts on the platform — set
railingH=0 for a bare deck
Distinct from --gen-mesh-tower (round castle tower with
crenellated battlements). A watchpost is the rough scout/
forward-outpost variant — just wood and rope, no masonry.
Pairs naturally with --gen-mesh-tent / --gen-mesh-firepit
for camp + lookout scenes, and --gen-mesh-fence for
perimeter setups. Watertight under weld (verified
108 manifold edges, 0 boundary, 0 non-manifold).
Two more boilerplate patterns repeated across cli_gen_mesh.cpp:
• init: 64 sites set wom.name = path-stem and wom.version = 3
in 3 lines. Hoisted to initWomDefaults(wom, base) — 1 line.
• save: 65 sites had identical 5-line "if save fails, fprintf
stderr and return 1" blocks. Hoisted to saveWomOrError(wom,
base, cmdName) returning bool, used as
`if (!saveWomOrError(...)) return 1;` — also 1 line.
Net cli_gen_mesh.cpp drops by ~254 lines (from 6424 to 6170).
Output bytes verified identical: firepit surface area 2.1100
m² unchanged, cube vertex/index/bounds counts unchanged.
After this batch's prior helpers (addFlatBox, addVertex,
stripExt, finalizeAsSingleBatch, parseOpt*), a typical new
gen-mesh handler now needs zero copy-paste boilerplate to
get a working primitive — every shared bit lives in
cli_box_emitter.hpp and cli_arg_parse.hpp.
63rd procedural mesh primitive. The first to explicitly
compose a *scene* of multiple objects rather than a single
structure: an N×M×K arrangement of cube crates with a small
gap between each so they read as discrete shipping boxes
rather than one merged solid.
Default 2×2×2 = 8 crates with 0.40 m sides on a 0.02 m gap
gives a tight pyramidal pile. Larger configurations (e.g.
4×3×2 = 24 crates) read as warehouse pallets.
Uses every shared helper added this batch — addFlatBox for
each crate, finalizeAsSingleBatch for the trailing batch,
stripExt for the .wom suffix, parseOptInt/Float for the
optional dimension args. Each crate emits the standard
24-vert / 12-tri box, so an N×M×K stack is a clean
N*M*K-multiple in vertices and triangles.
Useful for warehouses, cargo holds, dock loading bays,
market stalls, dwarven mining caches, pirate stash piles.
Watertight under weld — the gap keeps adjacent crates
from sharing corner positions.
53 procedural mesh primitives ended with the same 5-line
batch-finalization boilerplate:
wowee::pipeline::WoweeModel::Batch batch;
batch.indexStart = 0;
batch.indexCount = static_cast<uint32_t>(wom.indices.size());
batch.textureIndex = 0;
wom.batches.push_back(batch);
Hoist into cli_box_emitter.hpp as inline finalizeAsSingleBatch
(WoweeModel&). Each call site collapses to:
finalizeAsSingleBatch(wom);
cli_gen_mesh.cpp drops by ~210 lines. Output bytes verified
identical: firepit batch idx 0 / iStart 0 / iCount 360 /
opaque blend, surface area 2.1100 m² unchanged.
Procedural builders only ever emit one batch per primitive;
multi-batch primitives (none currently exist) would still
be free to construct batches manually.
64 sites in cli_gen_mesh.cpp open-coded the same 4-line
"strip .wom suffix from base path if user typed it" pattern:
if (womBase.size() >= 4 &&
womBase.substr(womBase.size() - 4) == ".wom") {
womBase = womBase.substr(0, womBase.size() - 4);
}
Hoist into cli_box_emitter.hpp as inline stripExt(string&,
const char*). Generic on the suffix string so future callers
can use it for ".wob" / ".woc" / ".png" too — uses
string::compare instead of substr to avoid the temporary
allocation the original did per check.
Each call site collapses to a single line:
stripExt(womBase, ".wom");
cli_gen_mesh.cpp drops by ~96 lines. Output bytes verified
identical: firepit surface area 2.1100 m² unchanged.
62nd procedural mesh primitive. A blacksmith / crafter
workbench built from axis-aligned boxes (uses the new
cli_box_emitter helper plus the new cli_arg_parse helpers
for all 7 optional dimension args):
• flat top slab spanning length × depth at topT thickness
• 4 corner legs sized so their outer faces line up with
the top edges (post-style, no overhang)
• optional vise box at the +X end of the top — set
viseSize=0 for a bare bench
• optional raised tool tray along the +Z back edge —
set trayH=0 to omit
Pairs naturally with --gen-mesh-anvil (existing) for
blacksmith forge scenes, and --gen-mesh-cauldron for
alchemist labs. Default 1.6×0.7×0.85 m bench reads at
realistic adult-human working height.
Watertight under weld (verified via --info-mesh-stats:
126 manifold edges, 0 boundary, 0 non-manifold).
Every --gen-texture-* and --gen-mesh-* handler had its own
copy of the same 3-line "if there's another arg AND it
doesn't look like a switch, parse it; otherwise keep the
default" block. 458 sites across cli_gen_texture.cpp and
cli_gen_mesh.cpp duplicated this pattern.
Hoist into cli_arg_parse.hpp as inline parseOpt{Int,Float,Uint}
(int& i, int argc, char** argv, T& value). Each call site
collapses from 3 lines to 1:
if (i + 1 < argc && argv[i + 1][0] != '-') {
try { width = std::stof(argv[++i]); } catch (...) {}
}
becomes
parseOptFloat(i, argc, argv, width);
cli_gen_mesh.cpp drops by ~250 lines, cli_gen_texture.cpp
by ~430 lines. Output bytes verified identical: firepit
default-arg surface area 2.1100 m² unchanged.
Future texture/mesh primitives now opt in by including one
header instead of pasting the lambda.
61st procedural mesh primitive. Builds a bedroll prop:
• horizontal closed cylinder along the Z axis sitting at
y = R so it rests on the ground (radius defaults to
0.16 m, length 1.4 m — adult-human-shaped)
• optional pillow box at the +Z end (squashed cube,
pillowSize controls extent)
• per-segment N-sided cylinder uses the new addVertex
helper; pillow uses addFlatBox
Set pillowSize=0 for a bare rolled mat. Watertight under
weld (verified via --info-mesh-stats: 90 manifold edges,
0 boundary, 0 non-manifold).
Pairs naturally with --gen-mesh-tent / --gen-mesh-firepit /
--gen-mesh-canopy for outdoor camp scenes — completes the
tent-side camping kit.
60th procedural mesh primitive. Builds a chimney as two
axis-aligned boxes (uses the shared addFlatBox helper):
• main shaft: rectangular brick stack of width × depth ×
(height - capH)
• protective cap: a slightly wider box on top (capExtra
wider than shaft on every side) — the rain-throw crown
that sits on real masonry chimneys
Set capH=0 for a bare unfinished stack. Default 0.45×0.45×
1.8 m shaft with a 0.10-tall cap reads at human scale for
rooftop placement.
Useful for cottage rooflines, blacksmith forges, alchemist
labs, dwarven longhouses — any structure with a fireplace
that needs visible vent. Watertight under weld (verified
via --info-mesh-stats: 36 manifold edges, 0 boundary, 0
non-manifold).
After the addBox extraction, 21 procedural mesh primitives
each still open-coded the same 5-line addV vertex-emit lambda.
Add inline addVertex(WoweeModel&, vec3, vec3, vec2) to
cli_box_emitter.hpp (header so the per-vertex hot loop stays
inlineable), plus a per-float overload for the four handlers
(--gen-mesh-stairs, --gen-mesh-tube, --gen-mesh-capsule,
--gen-mesh-arch) that compute pos/normal/uv components inline
rather than building intermediate glm vectors.
Each lambda site collapses from a 5-line body to a 3-line
forwarding wrapper. Output bytes verified identical via
--info-mesh-stats: firepit surface area 2.1100 m² unchanged
across all variants tested (stairs/tube/capsule/arch/
firepit/mushroom).
Sets up the pattern so the next "shared mesh helper" is one
line of include, not another paste-in.
59th procedural mesh primitive. Builds an open-top pergola
from axis-aligned boxes (uses the new addFlatBox helper):
• 4 corner posts sized so their outer faces line up with
the footprint perimeter
• 2 long perimeter beams resting on top of the posts
along the long edges
• N cross beams running between the perimeter beams
(slightly thinner so the lattice has visible crossings)
Distinct from --gen-mesh-canopy because there's no closed
overhead panel — the open lattice top reads as a sun-trellis
or vine-arbor instead of a market-stall awning. Useful for
palace courtyards, druid groves, garden mazes, viewing
arbors, harvest-festival entrance pieces.
Set crossbeams=0 for a bare 4-post + 2-beam frame; default
5 crossbeams gives a pleasing alternating pattern.
36 procedural mesh primitives in cli_gen_mesh.cpp each open-
coded the same ~30-line lambda for emitting a flat-shaded
axis-aligned box (per-face vertices for unique normals,
6 faces × 4 verts × 2 tris). Hoist the implementation into
cli_box_emitter.{hpp,cpp} as addFlatBox(WoweeModel&, ...)
with two overloads:
• addFlatBox(wom, cx, cy, cz, hx, hy, hz)
center + half-extents form, used by 34 primitives
• addFlatBox(wom, glm::vec3 lo, glm::vec3 hi)
lo/hi corners form, used by --gen-mesh-archway and
--gen-mesh-fence which compute corners directly
Each lambda site collapses from ~30 lines to a 3-line thin
wrapper: cli_gen_mesh.cpp drops from 7374 to 6989 lines.
Output bytes verified identical via --info-mesh-stats
(firepit surface area 2.1100 m² unchanged, vertex/triangle
counts match across firepit/canopy/dock/archway/fence).
Future box-based primitives now opt in by including one
header instead of pasting the lambda again.
58th procedural mesh primitive. Builds a wooden waterside
dock from axis-aligned boxes:
• flat plank deck slab spanning length × width at deckT
thickness, sitting at deckHeight off the ground
• N pairs of square pilings under the long edges, evenly
spaced from end to end
• pilings inset by pilingW so the deck overhangs slightly
(the standard "boards rest ON TOP of the posts" look)
Distinct from --gen-mesh-bridge which arches OVER an
obstacle — a dock walks straight out from a shoreline on
stilts to the water. Useful for fishing villages, port
warehouses, lake settlements, ferry stations, smuggler
hideouts.
Watertight under weld (--audit-watertight passes): pilings
sit below the deck overhang and don't share corners with it.
