サンプル

CanvasTexture defaults flipY to true to invert UV y-coordinates during transformUv, leaves transformUv unaffected by offset and repeat changes until updateMatrix is explicitly invoked despite matrixAutoUpdate being true, serializes metadata type as Texture, and dynamically queries width and height from its canvas source.

よくある思い込み

transformUv automatically synchronizes with texture offset and repeat when matrixAutoUpdate is enabled, and CanvasTexture serializes with metadata type CanvasTexture.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• CanvasTexture transforms UV coordinates with flipY inversion but leaves transformUv unaffected by offset or repeat changes until updateMatrix is called manually, even when matrixAutoUpdate is true.
• CanvasTexture constructor applies default texture wrapping, filtering, RGBA format, and NoColorSpace while dynamically computing width and height from the underlying canvas.
• Calling transformUv on non-UV mappings skips matrix transformation and flipY inversion entirely.
• Serializing CanvasTexture with toJSON outputs metadata type Texture rather than CanvasTexture and captures wrap, filtering, and flipY settings.
• Setting values with setValues copies Vector2 properties and dispatches synchronous events on dispose.
