示例

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.

常见的想当然

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

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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.
