VoxelPipe: A Programmable Pipeline for 3D Voxelization
(ACM, 2011)
We present a highly exible and e cient software pipeline for programmable triangle voxelization. The pipeline, entirely written in CUDA, supports both fully conservative and thinvoxelizations, multiple boolean, oating ...
Simpler and Faster HLBVH with Work Queues
(ACM, 2011)
A recently developed algorithm called Hierachical Linear Bounding Volume Hierarchies (HLBVH) has demonstrated the feasibility of reconstructing the spatial index needed forray tracing in real-time, even in the presence of ...
The Alchemy Screen-Space Ambient Obscurance Algorithm
(ACM, 2011)
Ambient obscurance (AO) produces perceptually important illumination effects such as darkened corners, cracks, and wrinkles; proximity darkening; and contact shadows. We present the AO algorithm from the Alchemy engine ...
