详细说明

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，请设置Texture 的textureData 属性以引用 TextureData 对象。

自定义纹理数据在 C++ 中是通过创建QQuick3DTextureData 实例（通常是子类）来实现的。QQuick3DTextureData 类型以 TextureData 的名称注册到 QML 中。一旦子类注册到 QML，Texture 对象就可以开始引用它。

使用此 API 的一个例子是，需要在运行时程序化地生成纹理，而不是从文件加载静态图像。

import MyCustomTexture 1.0

Model {
    source: "#Cube"
    materials: [
        DefaultMaterial {
            diffuseMap: diffuseMapCustomTexture
        }
    ]
}

Texture {
    id: diffuseMapCustomTexture
    textureData: MyCustomTextureData {

    }
}
