Texture.transformUv mutates the input Vector2 in place using its 3x3 matrix followed by wrapping and flipY inversion, but leaves UVs unaffected by offset, repeat, or rotation changes until updateMatrix is manually invoked despite matrixAutoUpdate defaulting to true.

흔히 이렇게 알고 있다

Texture.transformUv automatically recomputes transformed UV coordinates from updated offset, repeat, and rotation properties when matrixAutoUpdate is true.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• Texture.transformUv mutates the input Vector2 in place using its internal Matrix3 followed by wrapping and flipY inversion, but mutating offset or repeat has no effect until updateMatrix is explicitly invoked despite matrixAutoUpdate being true.
• Texture.transformUv applies RepeatWrapping, ClampToEdgeWrapping, and MirroredRepeatWrapping to out-of-bounds UV coordinates before applying flipY inversion.
• Setting texture mapping to non-UV modes like CubeReflectionMapping causes transformUv to return immediately without matrix transformation, wrapping, or flipY modification.
• Rotation around a configured center in Texture.updateMatrix properly transforms coordinates in accordance with the UV transform matrix.
