Instantiating CanvasTexture marks it immediately for update with version 1, while reading needsUpdate yields undefined because needsUpdate is a setter-only property that increments version counters.

흔히 이렇게 알고 있다

CanvasTexture initializes with version 0 like Texture, and reading needsUpdate returns a boolean indicating whether the texture is flagged for update.

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

컨트랙트

• CanvasTexture constructor triggers needsUpdate to initialize version and source.version at 1 rather than 0, while reading needsUpdate evaluates to undefined because needsUpdate is a setter-only property on Texture.
• Setting needsUpdate to true increments both texture.version and source.version by 1, whereas setting it to false leaves versions unchanged.
• Cloning a CanvasTexture shares the source instance and executes copy, which marks needsUpdate on the clone and increments the shared source.version.
