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).
