An Efficient Denoising Algorithm for Global Illumination
(ACM, 2017)
We propose a hybrid ray-tracing/rasterization strategy for real- time rendering enabled by a fast new denoising method. We factor global illumination into direct light at rasterized primary surfaces and two indirect lighting ...
Non-Linearly Quantized Moment Shadow Maps
(ACM, 2017)
Moment shadow maps enable direct filtering to accomplish proper antialiasing of dynamic hard shadows. For each texel, the moment shadow map stores four powers of the depth in either 64 or 128 bits. After filtering, this ...
A Hardware-Friendly Bilateral Solver Accelerator for Real-Time Virtual Reality Video
(ACM, 2017)
Rendering 3D-360° VR video from a camera rig is computationintensive and typically performed o ine. In this paper, we target the most time-consuming step of the VR video creation process, high-quality ow estimation with ...
Spatiotemporal Variance-Guided Filtering: Real-Time Reconstruction for Path Traced Global Illumination
(ACM, 2017)
We introduce a reconstruction algorithm that generates a tempo- rally stable sequence of images from one path-per-pixel global illumination. To handle such noisy input, we use temporal accu- mulation to increase the e ...
