Free GLSL Shaders
The following list includes WebGL shader source code for an amazing shrinking octagon, cool animated spotlight, and a zoom-in shader. Follow links to vertex shaders and fragment shaders. Some links include short tutorials and image texture maps.
What is a Shader?
WebGL shader's process data on hardware, called the graphics processing unit (GPU).
GPU's offer the capability to display 2D and 3D graphics much faster
than software. The hardware of a GPU's designed to process quickly.
WebGL shader's are written in the
C language. View shader source code,
read short tutorials and modify or use code as-is, to learn WebGL shader development.
