Detailed Description

Defines how an UV channel is transformed.

This is just a helper structure for the #AI_MATKEY_UVTRANSFORM 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 Data Documentation

float aiUVTransform::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.

C_STRUCT aiVector2D aiUVTransform::mScaling

Scaling on the u and v axes.

The default value is (1|1).

C_STRUCT aiVector2D aiUVTransform::mTranslation

Translation on the u and v axes.

The default value is (0|0).
