Package org.lwjgl.assimp
Class AIUVTransform
- All Implemented Interfaces:
AutoCloseable
,NativeResource
,Pointer
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.

AIUVTransform
Creates aAIUVTransform
instance at the current position of the specifiedByteBuffer
container. Changes to the buffer's content will be visible to the struct instance and vice versa.The created instance holds a strong reference to the container object.
