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

// GLSL declaration
uniform mat3 czm_inverseNormal;

// Example
vec3 normalMC = czm_inverseNormal * normalEC;
