GPU-based Out-of-Core HLBVH Construction

Mahmoud Zeidan, Taymoor Nazmy & Mostafa Aref
Recently the GPU has been used extensively in building indexing structures for moderately complex scenes that fit inside the GPU core. However, only few methods have been developed for constructing indexing structures for massive models larger than GPU memory. In this paper, we present an out-of-core HLBVH algorithm, a new method for constructing spatial hierarchies suitable for massive models that cannot fit into GPU device memory. A key insight of our method is how to...
