Q3Shader_GetUVTransform

You can use the Q3Shader_GetUVTransform function to get the current transform in uv parametric space.

TQ3Status Q3Shader_GetUVTransform (
TQ3ShaderObject shader, 
TQ3Matrix3x3 *uvTransform);

shader

A shader.

uvTransform

On exit, a pointer to the current transform in uv parametric space.

DESCRIPTION

The Q3Shader_GetUVTransform function returns, in the uvTransform parameter, the current transform in uv parametric space for the shader specified by the shader parameter.
