Tight Bounding Boxes for Voxels and Bricks in a Signed Distance Field Ray Tracer
Abstract
We present simple methods to compute tight axis-aligned bounding boxes for voxels and for bricks of voxels in a signed distance function renderer based on ray tracing. Our results show total frame time reductions of 20-31% in a real-time path tracer.
