}示例2: RotateAround
/*
* Rotate around a specific point and orientation vector.
*
* The point is specified by [px], [py], and [pz].
*
* The orientation vector is specified by [ax], [ay], and [az].
*
* The parameter [local] determines whether local or world space is used.
* If world space is used, it takes into account the aggregated transform
* of the scene object's ancestors.

}示例3: Translate

* determines if the transformation is relative to world coordinates or the transform's
* local space, which includes the aggregated transform of the scene object's ancestors.
