79th procedural texture: solid N-pointed star polygon
centered on the texture. Each pixel computes its polar
(r, θ); the star boundary at any θ alternates between
outer and inner radii using a 2π/N triangular-wave pattern
(0 at sector edges = points, 1 at sector center = valley).
Pixels with r < boundary(θ) are filled with the star color.
Distinct from --gen-texture-starburst (thin rays with bg
between them) and --gen-texture-pinwheel (alternating
solid wedges) — star is a single solid polygon shape.
innerFrac controls the star's "sharpness": near 0 gives
spike-thin star arms; near 1 approximates a circle. Default
0.40 with 5 points gives the classic American-flag star.
The first point is rotated to the top (-Y screen direction)
for canonical orientation.
Useful for medallion centers, shield emblems, religious /
order symbols, magic-circle icons, banner emblems, sheriff-
badge inserts.
Three new single-keyframe WOL presets complement the
existing 4-keyframe day/night cycle from --gen-light:
• --gen-light-cave — dim cool ambient (0.05, 0.05, 0.07)
+ heavy short-range fog (15..80)
for cave / mine interiors
• --gen-light-dungeon — warm torchlit ambient (0.18, 0.14,
0.10) + medium fog (25..200) for
dungeon / crypt interiors
• --gen-light-night — cold blue ambient (0.06, 0.07, 0.12)
+ moonlit directional + far fog
(80..500) for always-night zones
Each preset emits a single-keyframe WOL since enclosed /
fixed-time scenes don't vary with time-of-day. All three
share an emitLightPreset helper so adding more presets
(e.g. --gen-light-tundra, --gen-light-volcanic) is one
line of registration + a maker function.
All four WOL outputs validate clean under --validate-wol
(1 or 4 keyframe(s) valid).
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.
78th procedural texture: fine cracks following Voronoi cell
boundaries. For each pixel, the algorithm finds the two
nearest jittered cell centers (across 9 surrounding cells);
the difference between (distance to second-nearest) and
(distance to nearest) approximates distance to the cell
boundary line. Pixels under crackW from the boundary get
the crack color; inside cells get the base.
Distinct from --gen-texture-cracked (wide stone cracks at
large scale via random walk) and --gen-texture-frost
(6-spike crystal rosettes from seeded points) — crackle
is the fine-mud / dry-leather / parched-earth variant for
desert ground / aged-document / drought-cracked-mud zones.
Useful for desert-floor zones, aged-leather armor sections,
parched-earth dungeon floors, dragon-burned ground,
mummified-flesh trim, ancient-document parchment.
Three additions to the Wowee Open Light format that landed
last commit:
• WoweeLightLoader::sampleAtTime(light, timeMin) returns
the linearly-interpolated keyframe at any time-of-day,
correctly handling wrap-around between the last keyframe
and the first (e.g. 21:00 blends from dusk toward
midnight by going forward through 00:00).
• --validate-wol <wol-base> [--json] walks every keyframe
and reports structural problems: time bounds (must be
[0, 1440)), strict-ascending sort order, fogEnd >
fogStart, finite color components. Exit code 0 PASS /
1 FAIL — CI-friendly.
• --info-wol-at <wol-base> <HH:MM|minutes> samples the
interpolated state at a specific time of day. Useful
for previewing what the renderer would feed in at a
given moment, debugging keyframe gaps, or previewing
a sub-range of the cycle.
Smoke-tested: dawn-to-midnight blend at 03:00 yields a
plausible mid-fade ambient (0.18, 0.16, 0.15) and dusk-to-
midnight wrap at 21:00 yields the symmetric (0.19, 0.145,
0.14). The default 4-keyframe day/night cycle from
makeDefaultDayNight passes --validate-wol cleanly.
New open replacement for WoW's Light.dbc / LightParams.dbc /
LightIntBand.dbc / LightFloatBand.dbc stack — a single .wol
file holds a list of time-of-day keyframes for one zone,
each capturing the ambient + directional + fog state at that
moment. The renderer interpolates between adjacent keyframes
by time-of-day.
Binary layout:
magic[4] = "WOLA", version (uint32),
nameLen + name bytes,
keyframeCount + keyframes (each 13 floats + 1 uint32 time)
Per keyframe:
• timeOfDayMin (0..1439 = minutes since midnight)
• ambientColor.rgb, directionalColor.rgb, directionalDir.xyz
• fogColor.rgb, fogStart, fogEnd
CLI:
• --gen-light <wol-base> [zoneName] — emit a starter file
with 4-keyframe day/night cycle (midnight/dawn/noon/dusk)
using reasonable outdoor defaults
• --info-wol <wol-base> [--json] — inspect: zone name +
per-keyframe time-of-day + colors + fog distances
The 7th open-format addition to the Wowee pipeline:
M2 → WOM (model)
WMO → WOB (building)
WMO collision → WOC
ADT → WOT (terrain)
DBC → JsonDBC
BLP → PNG
Light.dbc family → WOL ← new
Smoke-tested round-trip: gen → info shows correct 4 keyframes
at 00:00 / 06:00 / 12:00 / 18:00 with the canonical color
ramps. JSON output for tooling integration.
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.
77th procedural texture: base metal color overlaid with N
short angled line segments brightened against the base.
Each scratch is a hash-derived (cx, cy, length, angle)
segment drawn via integer-stepped line walking from
-len/2 to +len/2 along the angle.
Useful for weathered armor, worn weapon blades (especially
old swords / axes that have seen real use), well-used metal
tools, salvaged hull plating, ancient relic surfaces,
dwarven heirloom finishes.
Default 100 scratches at maxLen=24 gives a moderately worn
look on 256x256; bump scratchCount + maxLen for a heavily
battle-scored aesthetic. Deterministic from seed.
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.
76th procedural texture: N alternating colored triangular
wedges radiating from the texture center, each subtending
2π/N radians. Each pixel computes its angle via atan2 and
maps to a sector index; even sectors get color A, odd get
color B.
Distinct from --gen-texture-starburst (thin rays with bg
between them) and --gen-texture-swirl (curved spiral arms)
— pinwheel uses solid-fill alternating wedges with no bg.
Useful for ceiling-decoration medallions, sun-mandala
designs, magical-wheel symbols, wind-rose floor inlays,
heraldic radial backgrounds, druid-circle ground markings.
Default 8 sectors gives the classic pinwheel look; bump
to 12-16 for finer subdivisions, or drop to 2-4 for bold
quadrant patterns.
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).
75th procedural texture: N small water droplets at hash-
derived (cx, cy, R) positions blended onto bg via radial
brightness — bright at the drop center fading to bg at its
edge. Where drops overlap they accumulate brighter
(max-of-individual-contributions, not additive — so the
result stays inside the [bg, drop] color range).
Each drop gets a hash-derived radius in the [maxR/4, maxR]
range so the surface has a natural mix of small and large
droplets. Two-pass (compute brightness map, then write
pixels) so overlap accumulation works correctly.
Useful for morning-grass blades, wet-glass overlays, leaf
surfaces after rain, magic-pool fizz, snake-fountain
splash zones, dragon-breath-aftermath ground.
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.
74th procedural texture: vertical light-beam / sun-ray
gradient. Each pixel's brightness is the product of two
fade factors:
• vertical: 1.0 at the bright end, vFadeFrac at the dim
end (direction flag selects bright-top 'd' or bright-
bottom 'u')
• radial: 1.0 inside the bright core (within beamHalfW of
centerline), then linearly to 0.0 at the texture edge
Two-color blend from bgHex to beamHex by combined brightness.
Useful for dust-mote sunbeams through cathedral windows,
holy radiance auras, crystal glow halos, lighthouse beams,
projector / stage-light columns, ritual-summoning effects.
First procedural texture with a directional flag (u / d) —
flexible orientation for ceiling-down vs floor-up beams.
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).
73rd procedural texture: a grid of X-shape cross stitches.
Each cell holds an X formed by two diagonal strokes from
opposing cell corners through the center. A pixel falls on
a stitch if its in-cell position is within strokeW/2 of
either diagonal axis.
Distinct from --gen-texture-checker (filled squares),
--gen-texture-knit (V-stitch chevron), --gen-texture-lattice
(diagonal trellis). Embroidery is the explicit two-direction
diagonal stitch mark used by counted-thread textile work.
Useful for sampler-cloth detail, folk-art trim, peasant-
clothier border bands, witch-hut wall hangings, hearth-rug
overlays. Default 12-cell / 2-stroke gives a fine X-stitch
look; bump cellSize for chunkier sampler stitches.
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.
72nd procedural texture: Worley (cellular) noise thresholded
into mold patches. Each grid cell hosts a hash-jittered
center; each pixel computes its distance to the nearest
center across 9 surrounding cells (current + 8 neighbors)
and is painted as mold if that distance is below
thresholdFrac × stride.
Distinct from --gen-texture-moss (single-spot per cell with
hash-derived presence/jitter/radius) — mold has irregular
field-shaped patches following the Voronoi cell boundaries
rather than discrete circles, mimicking real fungal growth
along surfaces.
Useful for cellars, dungeon walls, plague zones, sewer
overflow, food-warehouse spoilage, witch-hut detail trim.
Default 18-stride / 0.55-threshold gives a moderate
infestation; bump threshold near 0.9 for full coverage.
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).
71st procedural texture: vertical wood-grain streaks (like
--gen-texture-bark) overlaid with horizontal "plate" bands
at regular Y intervals — the segmented look of mature
hardwood / ironwood / sycamore bark.
Per-pixel logic:
• horizontal crack: top crackW pixels of every plateY
cycle gets the dark crack color
• vertical streak: per-streak hash determines an offset
crack position within each streakSpacing block
• elsewhere: base color modulated by per-streak-and-plate
brightness jitter (±15) so the surface has natural
texture variation
Distinct from --gen-texture-bark (vertical-crack only) and
--gen-texture-wood (vertical-streak only). Useful for ancient
trees, druid grove deadwood, dwarven hardwood beams,
fortress door planks, totem-pole carvings.
Parity with the WOM-side --audit-watertight --summary added
last batch. Same one-line rollup format for CI dashboards:
watertight-wob: PASS (1 buildings, 0 failure(s)) [/tmp/migtest, weld 0.001000]
watertight-wob: FAIL (12 buildings, 4 failure(s)) [/tmp/zone, weld 0.001000]
Format: "watertight-wob: <PASS|FAIL> (<N> buildings, <K>
failure(s)) [<root>, weld <eps>]". Exit code unchanged —
failure count capped at 255.
Both --audit-watertight (WOM) and --audit-watertight-wob
(WOB) now offer the same trio of output modes: verbose
(default), --json (machine-readable), --summary (one-line
CI rollup).
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).
CI-friendly one-line rollup mode for the welded watertight
audit. Replaces the per-mesh PASS/FAIL detail lines with a
single status line:
watertight: FAIL (121 meshes, 27 failure(s)) [/tmp/migtest, weld 0.001000]
watertight: PASS (6 meshes, 0 failure(s)) [/tmp/camp, weld 0.001000]
Format: "watertight: <PASS|FAIL> (<N> meshes, <K> failure(s))
[<root>, weld <eps>]". Exit code unchanged — failure count
capped at 255, matching the verbose-mode contract.
Useful for build dashboards / CI grep lines / Slack-bot
notifications where the full per-mesh dump would be too
noisy. Verbose mode is still the default; opt in with
--summary.
70th procedural texture: N-arm logarithmic spiral. Each
pixel computes its polar angle minus log(r)*spiralFactor
and tests whether that "spiral phase" falls inside any
arm's angular band (mod 2π/N).
Distinct from --gen-texture-starburst (straight rays from
center) — this is the curved-arm vortex variant. Small
spiralFactor gives loose pinwheel arms; large factor gives
tight whirlpool spirals.
Useful for magic sigils, summoning circles, ritual floor
markings, mystical-pool surfaces, mage-tower mosaic floors,
shaman-totem ground inlays. Center-based pattern (doesn't
tile seamlessly), so best used as standalone decals rather
than wall textures.
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.
69th procedural texture: stack of parallel sinusoidal curves
spaced verticalSpacing apart. A pixel falls on a dune line
if its Y is within lineW/2 pixels of the nearest curve at
y = N*spacing + amp*sin(2π*x/period).
Distinct from --gen-texture-corrugated (uniform parallel
lines) and --gen-texture-zebra (sin-shifted strip fills) —
this is the discrete-curve variant for desert ground
textures and shallow-water sand patterns.
Useful for desert ground, shallow-water sand bottoms,
beach close-ups, mirage scene-setters, sand-storm overlays,
zone-specific weathering on stone surfaces.
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.
68th procedural texture: stack of V-shape stripes with
sharp seams. Within each vertical period the upper half
slopes one way and the lower half slopes the other; the
distance from the apex is added as an x-shift to the
stripe-column test, so stripes follow the V profile and
form clean chevrons.
Distinct from --gen-texture-herringbone (which alternates
slab orientation between cells) and --gen-texture-zebra
(sinusoidal stripes with no seam) — chevron has the
characteristic sharp V transition.
Useful for military insignia, sportswear, heraldic banners,
roadwork signage, paladin tabards, ranger cloaks. Default
24-period / 24-stride / 6-wide gives a chunky chevron at
256x256; tighter values read as fine ribbon trim.
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.
66th procedural texture: axis-aligned grid of solid diamond
shapes (no row offset) separated by visible bg gaps. Each
cell hosts one diamond computed via L1 (taxicab) metric:
|dx|/halfW + |dy|/halfH < fillFrac.
Distinct from --gen-texture-snake-skin (brick-offset diamonds
that touch tangentially with a derived dark outline) — this
variant uses uniform spacing and a configurable fill fraction
so diamonds float in clean grid rows.
fillFrac = 0.80 default gives a 20% bg-gap moat between
diamonds; bump near 1.0 for nearly-touching chevron-floor
look, drop to 0.5 for sparse polka-diamond.
Useful for clean tile floors, mosaic inlay panels, banner
seamless backgrounds, formal heraldry trim, jeweled-cloak
tabards.
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.
65th procedural texture: 2 sets of parallel "translucent"
bands — one horizontal, one vertical — overlaid on a base.
Each band contributes 0.5 alpha, so where bands cross both
half-alphas combine for the darkest color (the unmistakable
plaid grid intersection).
Distinct from --gen-texture-tartan (3-4 colors with
asymmetric stripe pitches) — this is the simple symmetric
2-color variant. Distinct from --gen-texture-checker (hard
binary squares) — plaid uses 3-tone alpha-blend gradient.
Useful for pub-table cloths, country-tavern napery, dwarven
formal-attire trim, picnic blankets, peasant-clothier
swatches. Default 24-stride / 8-band reads as classic
country-checked at 256x256.
First procedural texture to also use the new printPngWrote
helper from this batch.
63 procedural-texture handlers each printed the same two-line
success header at the start of their stat block:
std::printf("Wrote %s\n", outPath.c_str());
std::printf(" size : %dx%d\n", W, H);
The size label had minor whitespace variation (label widths
of 8-15 chars chosen to align with longer per-handler labels).
Hoist into cli_png_emit.hpp as inline printPngWrote(outPath,
W, H) which normalizes to a uniform 11-char label.
Each call site collapses to one line. Output bytes
verified identical via PNG diff: regenerating moss.png with
same args produces byte-for-byte the same file. The visible
text output now uses one consistent label width across all
gen-texture-* commands instead of the previous per-handler
spacing tweaks.
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).
64th procedural texture: vertical rust drips on a metal base.
Each streak is a hash-derived (x position, width 1..4 px,
top y, length H/3..H) band that fades from full rust at the
top to bg at the bottom — the "streak" effect of years of
rain washing rust down from rivets and seams.
Distinct from --gen-texture-rust (generic surface noise) —
this is the directional-drip variant for:
• weathered metal walls (especially under high windows)
• sewer-grate backings under standing puddles
• ship-hull stains below scupper ports
• abandoned-machinery panels under leaking pipes
Deterministic from seed: re-running with same args produces
the byte-identical image. Default 40 streaks at 256x256
gives a reasonable "lightly aged" intensity; bump
streakCount for heavier corrosion.
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.
