Screen-Space Far-Field Ambient Obscurance
(ACM, 2013)
Ambient obscurance (AO) is an effective approximation of global illumination, and its screen-space (SSAO) versions that operate on depth buffers only are widely used in real-time applications. We present an SSAO method ...
Imperfect Voxelized Shadow Volumes
(ACM, 2013)
Voxelized shadow volumes [Wyman 2011] provide a discretized view-dependent representation of shadow volumes, but are limited to point or directional lights. We extend them to allow dynamic volumetric visibility from area ...
Real-time Local Displacement using Dynamic GPU Memory Management
(ACM, 2013)
We propose a novel method for local displacement events in large scenes, such as scratches, footsteps, or sculpting operations. Deformations are stored as displacements for vertices generated by hardware tessellation. ...
