Class GLTextureFilterParameters

java.lang.Object
  codeanticode.glgraphics.GLTextureFilterParameters

public class GLTextureFilterParameters
extends java.lang.Object

This class stores the parameters for a filter. There are 6 predefined parameters: three float numbers and three matrices (2x2, 3x3 and 4x4). This parameters should correspond to uniform parameters defined in the shader code.
