```
public class AIUVTransform
extends Struct
implements NativeResource
```
Defines how an UV channel is transformed.
This is just a helper structure for the Assimp._AI_MATKEY_UVTRANSFORM_BASE key. See its documentation for more details.

Typically you'll want to build a matrix of this information. However, we keep separate scaling/translation/rotation values to make it easier to process and optimize UV transformations internally.

Member documentation
- mTranslation – Translation on the u and v axes. The default value is (0|0).
- mScaling – Scaling on the u and v axes. The default value is (1|1).
- mRotation – Rotation - in counter-clockwise direction. The rotation angle is specified in radians. The rotation center is 0.5f|0.5f. The default value 0.f.
