czm_inverseNormal
An automatic GLSL uniform representing a 3x3 normal transformation matrix that transforms normal vectors in eye coordinates to model coordinates. This is the opposite of the transform provided by czm_normal.
Example
1 2 3 4 5 | // GLSL declaration uniform mat3 czm_inverseNormal ; // Example vec3 normalMC = czm_inverseNormal * normalEC; |
