- mesh_draw: removed redundant ib null check - game_test: cubes moved to z=0.3-0.8 (within near/far range) - raw3d_test verified 3D rendering works correctly
- mesh_load_obj: parse vertices, UVs, faces from .obj files - Auto-generate face normals - Per-face vertex expansion (simple but correct)
核心热路径(数学/内存/字符串/性能分析)用MASM汇编(SSE/AVX2) 外围系统(窗口/渲染/ECS/音频/UI/脚本)用C语言 含自研编辑器、VisualScript积木编程、中文渲染(glyph_atlas)
