Phase 2 performance: BVH acceleration with median-split build, per-model trees, and EBO re-sorting for GPU cache coherence. Raw binary .ifcview sidecar stores full geometry + BVH for instant subsequent loads (skip tessellation entirely). Per-model GPU buffers (VAO/VBO/EBO per model) eliminate cross-model buffer copies on growth. Sidecar reads happen on a background thread. Bulk GPU uploads are progressive (48 MB/frame chunks) so the viewport stays interactive while multi-GB models stream in. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
