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.

OpenVIDIA Computer Vision on GPUs Project The OpenVIDIA project is a GPL'd Free/Open Source project which implements computer vision algorithms on the GPU using OpenGL and Cg. These papers describe the GPU implementation of a projective image registration algorithm in OpenVIDIA. The current release includes a hand-tracking program used for a gesture recognition interfaces, some simple programming examples, and firewire video input support. OpenVIDIA explores the use of GPU hardware accelerated computer vision in the context of creating Computer Mediated Reality.

Posted: 17 May 2004 [GPGPU /Image And Volume Processing/Computer Vision] # Typhoon Labs OpenGL Shader Designer 1.3 Typhoon Labs has released version 1.3 of the OpenGL Shader Designer, an integrated development environment for GPU fragment and vertex shaders in GLSL (the OpenGL shading language). Key features include plugins for vertex attributes (tangents, binormals, etc.), textures (noise, volumes, etc.), real-time preview with multiple light sources, full syntax highlighting and "intellisense" for GLSL, and much more!
