Real-Time Diffuse Global Illumination Using Radiance Hints
(ACM, 2011)
GPU-based interactive global illumination techniques are receiving an increasing interest from both the research and the industrial community as real-time graphics applications strive for vi-sually rich and realistic dynamic ...
Active Thread Compaction for GPU Path Tracing
(ACM, 2011)
Modern GPUs like NVidia s Fermi internally operate in a SIMD manner by ganging multiple (32) scalar threads together into SIMD warps; if a warp s threads diverge, the warp serially executes both branches, temporarily ...
SSLPV: Subsurface Light Propagation Volumes
(ACM, 2011)
This paper presents the Subsurface Light Propagation Volume (SSLPV) method for real-time approximation of subsurface scattering effects in dynamic scenes with changing mesh opology and lighting. SSLPV extends the Light ...
Improving SIMD Efficiency for Parallel Monte Carlo Light Transport on the GPU
(ACM, 2011)
Monte Carlo Light Transport algorithms such as Path Tracing (PT), Bi-Directional Path Tracing (BDPT) and Metropolis Light Transport (MLT) make use of random walks to sample light transport paths. When parallelizing these ...
Voxelized Shadow Volumes
(ACM, 2011)
Efficient shadowing algorithms have been sought for decades, but most shadow research focuses on quickly identifying shadows on surfaces. This paper introduces a novel algorithm to efficiently sample light visibility at ...
Hierarchical Stochastic Motion Blur Rasterization
(ACM, 2011)
We present a hierarchical traversal algorithm for stochastic rasterization of motion blur, which efficiently reduces the number of inside tests needed to resolve spatio-temporal visibility. Our method is based on novel ...
Depth Buffer Compression for Stochastic Motion Blur Rasterization
(ACM, 2011)
Previous depth buffer compression schemes are tuned for compressing depths values generated when rasterizing static triangles. They provide generous bandwidth usage savings, and are of great importance to graphics processors. ...
