Walks every .wom and .wob under <zoneDir>, optionally welds
each one independently (per-mesh / per-WOB-group), and
appends its triangles to a single WoweeCollision. Useful for
shipping a zone — one .woc artifact holds all object collision
so the server side has just one file to load.
Per-file weld preserves between-object boundaries: two
distinct WOMs sitting at the same world position keep
their topology separate even if their corner positions
happen to overlap.
Same flag surface as the single-file bakers: optional
[out.woc] (defaults to <zoneDir>/zone.woc), --weld <eps>,
--steep <deg> for the walkable/steep slope cutoff.
Smoke tested over /tmp/migtest: scanned 79 WOM + 1 WOB,
produced 9259-triangle WOC (1563 walkable, 1943 steep)
with correct world bounds.
Sibling of --bake-wom-collision for buildings. Walks every
group in a WOB, optionally welds vertices PER GROUP (groups
are intentionally separate — rooms with portals between them,
so welding across groups would fuse walls that should remain
distinct collision surfaces), and appends each to a single
WoweeCollision via WoweeCollisionBuilder::addMesh.
Same flag surface as the WOM variant: optional [out.woc]
output path, --weld <eps> for per-group vertex merge,
--steep <deg> for the walkable/steep slope cutoff.
Smoke tested on a 1-group cube WOB: 8 verts → 12-triangle
WOC with proper bounds (-1,-1,-1)..(1,1,1) and walkable/
steep classification matching the cube face orientations.
Three callers were each open-coding the same quantize-and-
bucket pass over vertex positions: --info-mesh-stats,
--info-wob-stats, and --bake-wom-collision. Move the
implementation to cli_weld.{hpp,cpp} as buildWeldMap() and
have each caller pass a flat positions array.
Identical std::map-based exact-equality keying preserved
(unbalanced-hash collisions remain absent). All three call
sites verified to produce byte-identical output:
• info-mesh-stats firepit: 240→80 verts, 0 boundary
• info-wob-stats cube: 8→8 verts, watertight YES
• bake-wom-collision tent: 18→6 verts, 8-tri WOC
About 75 lines of duplication removed; future weld-using
commands now opt in by including one header.
Convert any WOM mesh into a WOC collision file via
WoweeCollisionBuilder::addMesh, with optional --weld <eps>
that merges shared positions into a single canonical index
before baking. The weld pass is what makes per-face-shaded
procedural primitives produce a properly indexed collision
mesh — adjacent faces that previously authored 4 unique
verts per face now share 1 corner across all incident
faces, so raycasts can traverse edges naturally.
Also accepts --steep <deg> to control the walkable/steep
classification threshold (default 50° from horizontal,
matching the terrain pipeline).
Smoke-tested end-to-end:
• firepit: 240 verts → WOC with 120 tris (20 walkable
floor, 20 steep stone walls, rest neutral)
• tent_solid: 18 verts welds to 6, produces 8-tri WOC
• canopy: 216 → 56 weld, 108 tris, 30° steep cut
Pairs naturally with --info-mesh-stats --weld for
collision-quality QA before baking.
Moves the 3D-export bake handlers out of main.cpp:
--bake-zone-glb --bake-zone-stl --bake-zone-obj
--bake-project-obj --bake-project-stl --bake-project-glb
The STL + GLB project bakes share a combined dispatcher (one
function with internal STL-vs-GLB branching) since they walk
the same per-zone asset list and only differ in the output
emission code.
main.cpp drops 12,119 → 11,261 lines (-858). The combined-OR
opener spanning multiple lines created a parse-error fragment
in the extraction; caught + manually fixed before commit
(same pattern as the WOM info attachments/particles/sequences
extraction).
