Watertight Ray Traversal with Reduced Precision
(The Eurographics Association, 2016)
Reduced precision bounding volume hierarchies and ray traversal can significantly improve the efficiency of ray tracing through low-cost dedicated hardware. A key approach to enabling reduced precision computations during ...
Coarse Pixel Shading
(The Eurographics Association, 2014)
We present a novel architecture for flexible control of shading rates in a GPU pipeline, and demonstrate substantially reduced shading costs for various applications. We decouple shading and visibility by restricting and ...
Layered Reconstruction for Defocus and Motion Blur
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Light field reconstruction algorithms can substantially decrease the noise in stochastically rendered images. Recent algorithms for defocus blur alone are both fast and accurate. However, motion blur is a considerably more ...
