General-Purpose Computation Using Graphics Hardware
|
IntroductionGPGPU stands for General-Purpose computation on GPUs. With the increasing programmability of commodity graphics processing units (GPUs), these chips are capable of performing more than the specific graphics computations for which they were designed. They are now capable coprocessors, and their high speed makes them useful for a variety of applications. The goal of this page is to catalog the current and historical use of GPUs for general-purpose computation.

Faogen 2.0: Ambient occlusion calculation on the GPU Faogen ia a Fast Ambient Occlusion Generator. It uses a GPU to accelerate computation of ambient occlusion and bent normals both as per-vertex data and in texture images. Faogen 2.0 provides updated ambient aperture and bent normal shaders customizable by editing two simple GLSL functions. Other features include improved precision on large scale models, adjustable background for AO texture images, lighting animation control and bugfixes. (Faogen)
Posted: 04 Aug 2008 [GPGPU /Advanced Rendering] # Semi-uniform Adaptive Patch Tessellation This paper by Dyken, Reimers, and Seland of University of Oslo and SINTEF ICT presents an adaptive tessellation scheme for parametric patches producing consistent and watertight tessellations. The scheme uses only a few base tessellations and is particularly well suited for use
with instancing. In addition, a novel GPGPU bucket sort approach based on HistoPyramid is presented. The paper gives implementational details
and performance benchmarks. (Semi-uniform Adaptive Patch Tessellation. C. Dyken, M. Reimers, and J. Seland. Computer Graphics Forum, to appear.)
