Method Details
- genLTCMatrix
  
  public static int genLTCMatrix(boolean useTextureStorage)
  
  OpenGL 3.0+
  The isotropic LTC matrix 2D texture, 64*64 vec4 layout.
  Build for the roughness, sqrt(1.0f - NdotV) parameterization.
  
  Returns:
  
  InvMatrix(m[0].x, m[0].z, m[2].x, m[2].z);
- genLTCMagnitudeSplit
  
  public static int[] genLTCMagnitudeSplit(boolean useTextureStorage)
  
  OpenGL 3.0+
  The isotropic LTC magnitude 2D texture, 64*64 vec2&float layout.
  
  Returns:
  
  int[] = {Integral(GGX norm, fresnel), Clipping(sphere for horizon-clipping)};
- genLTCMagnitude
  
  public static int genLTCMagnitude(boolean useTextureStorage)
  
  OpenGL 3.0+
  The isotropic LTC magnitude 2D texture, 64*64 vec3 layout.
  
  Returns:
  
  Magnitude(GGX norm, fresnel, sphere for horizon-clipping);
