OpenGL also contains the compiler and runtime environment for shaders written in the the GLSL shader language. This brings us to the next piece, shaders. A shader is a small program that runs (ideally ...

Those intersections are then sent to a shader program running on the GPU, which determines whether the object is opaque (a "hit" for the ray-tracing algorithm) or transparent (i.e., the ...

It is a pixel shader program documented in this PDF that runs every frame in a scant millisecond or two. Where it sees pixels that create an artificial edge, it smooths them.

The patent is for a method for graphics processing that “includes executing, on a graphics processing unit (GPU), a shader program that performs ray tracing of a 3D environment represented by an ...

Exploiting the power of 3GS required a huge rewrite of your graphic engine and often learning a new language - GLSL. Some of the speed up of 4S can be exploited up by selecting better shaders - if you ...

The latest and biggest 3D games often seem to have a problem with stuttering. Ask around and finger of blame often points to shader compilation. But why, ...
