Efficient GPU Rendering of Subdivision Surfaces using Adaptive Quadtrees

Category: DevelopersComments

Aug 06, 2016

How does Pixar represent objects rendered in their movies?  With subdivision surfaces. Now researchers at Activision, NVIDIA, and Stanford have published a new adaptive quadtree approach to rendering subdivision surfaces on modern GPUs.  Using OpenGL tessellation shaders, their system efficiently renders subdivision surfaces by streaming the surface patches without needing to split the patches the way prior approaches, such as OpenSubdiv 3.0, operate.  Their accompanying YouTube video shows their technique rendering state-of-the-art video game assets.
