注意：这是一个不可创建的类型。无法在 QML 中实例化。
详细描述
自定义纹理数据允许使用应用程序生成的纹理数据，这些数据也可能动态变化。要使用自定义纹理数据，请将Texture 的textureData 属性设置为引用一个TextureData对象。
在 C++ 中，通过创建QQuick3DTextureData 实例（通常是其子类）来实现自定义纹理数据。QQuick3DTextureData 类型以 TextureData 的名称注册到 QML 中。一旦子类在 QML 中注册，Texture 对象即可开始引用它。
此 API 的使用场景示例包括：当需要在运行时程序化地生成纹理，而非从文件中加载静态图像时。
import MyCustomTexture 1.0
Model {
source: "#Cube"
materials: [
DefaultMaterial {
diffuseMap: diffuseMapCustomTexture
}
]
}
Texture {
id: diffuseMapCustomTexture
textureData: MyCustomTextureData {
}
