Class ARBMatrixPalette

java.lang.Object

org.lwjgl.opengl.ARBMatrixPalette

public class ARBMatrixPalette
extends java.lang.Object

Native bindings to the ARB_matrix_palette extension.

This extension extends the abilities of ARBVertexBlend to include a palette of modelview matrices. The n vertex units use a palette of m modelview matrices. (Where n and m are constrained to implementation defined maxima.) Each vertex has a set of n indices into the palette, and a corresponding set of n weights. Matrix indices can be changed for each vertex (between Begin and End).

When this extension is utilized, the enabled units transform each vertex by the modelview matrices specified by the vertices' respective indices. These results are subsequently scaled by the weights of the respective units and then summed to create the eyespace vertex.

A similar procedure is followed for normals. Normals, however, are transformed by the inverse transpose of the modelview matrix.
