czm_tangentToEyeSpaceMatrix
Creates a matrix that transforms vectors from tangent space to eye space.
Parameters:
| Name | Type | Description |
|---|---|---|
normalEC |
vec3 | The normal vector in eye coordinates. |
tangentEC |
vec3 | The tangent vector in eye coordinates. |
binormalEC |
vec3 | The binormal vector in eye coordinates. |
Returns:
mat3
The matrix that transforms from tangent space to eye space.
Example
mat3 tangentToEye = czm_tangentToEyeSpaceMatrix(normalEC, tangentEC, binormalEC); vec3 normal = tangentToEye * texture2D(normalMap, st).xyz;
