public final class ARBTextureGather
extends java.lang.Object
This extension provides a new set of texture functions (textureGather) to the shading language that determine 2x2 footprint that are used for linear filtering in a texture lookup, and return a vector consisting of the first component from each of the four texels in the footprint.
Promoted to core in OpenGL 4.0.
