|Applies torque (rotation momentum) to the [[getCenterOfMass | center of mass]] of the given object. Torque force is defined as vector [x, y, z] applied in world space. If you need to define torque in model space, convert the torque vector first by [[vectorModelToWorld]] or [[vectorModelToWorldVisual]] command. The torque applied as impulse. Diagram below explain which way the object would rotate.
