Title:

    Fast, High Precision Ray/Fiber Intersection using Tight, Disjoint Bounding Volumes

Presenter(s)/Author(s):



Abstract:


    We improve the performance of subdivision-based ray/fiber intersection for fibers along Bézier curves by pruning with tight, disjoint bounding volumes in ray-centric coordinate systems. The resulting method calculates precise intersections on the surface of a fiber with accurate normals, and performs significantly faster for a high number of subdivisions than state-of-the-art methods pruning sub-regions with axis-aligned bounding boxes.
