Y. J. Kim. Sung-eui Yoon. We present a novel, compact bounding volume hierarchy, TSS BVH, for ray tracing subdivision surfaces computed by the Catmull-Clark scheme. We use Tetrahedron Swept Sphere ...

surface. Mueller et al. [MTF03] present a method to adaptively ray trace subdivision surfaces. Both methods use single ray implemen-tations and were far from interactive. 3 Ray Tracing Subdivision Surfaces In this section, we explain how we directly intersect a ray with a Catmull-Clark subdivision surface. We first sketch this for a single

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Subdivision surfaces are the modeling primitive of choice for most production studios. Scanline rendering of subdivision surfaces via tessellation is relatively straightforward due to the in-order nature of the geometry processing, but directly ray tracing them is more complicated.

We present a fast and efficient method for intersecting rays with Catmull-Clark subdivision surfaces. It takes advantage of the approximation democratized by OpenSubdiv, in which regular patches are represented by tensor product Bézier surfaces and irregular ones are approximated using Gregory patches. Our algorithm operates solely on the original patch data …
