- bsp.load: parse Q3 BSP from pk3 (zip) archives via libzip - Extracts vertices, faces, meshverts from BSP lumps - Coordinate conversion: Q3 Z-up → engine Y-up - Configurable scale (default 1/32 = Q3 units to meters) - Skips sky, clip, trigger, caulk, hint textures - Bullet btBvhTriangleMeshShape collision from BSP geometry - draw.map: graceful fallback when shadow texture missing - Q3 game workflow: FPS controls, 90° FOV, walk around maps - Tested with q3dm17 (The Longest Yard): 8486 verts, 5128 tris - libzip added to cmake dependencies Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
