Methods
Destroys the WebGL resources held by this object. Destroying an object allows for deterministic
释放 WebGL 资源,而不是依赖垃圾收集器来摧毁此对象.
Once an object is destroyed, it should not be used; calling any function other than
Once an object is destroyed, it should not be used; calling any function other than
isDestroyed will result in a DeveloperError exception. Therefore,
assign the return value (undefined) to the object as done in the example.
Throws:
-
DeveloperError : This object was destroyed, i.e., destroy() was called.
Example:
skyAtmosphere = skyAtmosphere && skyAtmosphere.destroy();See:
如果此对象被销毁, 返回真实; 否则, 错误 .
If this object was destroyed, it should not be used; calling any function other than
If this object was destroyed, it should not be used; calling any function other than
isDestroyed will result in a DeveloperError exception.
Returns:
true if this object was destroyed; otherwise, false.
