public method SetTRS(pos: Vector3, q: Quaternion, s: Vector3): void;
public void SetTRS(Vector3 pos, Quaternion q, Vector3 s);

Description

Sets this matrix to a translation, rotation and scaling matrix.

The current matrix is modified so that it places objects at position pos, oriented in rotation q and scaled by s.
