Sean McNett has released a new geometric rejection primitive, the Bounding Simplex, designed specifically for modern SIMD-based hardware. Unlike traditional Axis-Aligned Bounding Boxes (AABBs), this method leverages vectorization to discard non-intersecting primitives more efficiently during spatial queries. However, the primitive's overhead in branch-heavy environments has not yet been benchmarked against industry-standard BVH (Bounding Volume Hierarchy) traversals. Whether this approach delivers measurable speedups in production-grade engines will likely depend on how it scales with complex, high-poly geometry.
