Detailed Description

Being rendered, the elements modifies current model-view matrix such that the axes of the specified reference system (in model space) become oriented in the following way:

• X - heads to the right side of view.
• Y - heads to the up side of view.
• N(Z) - heads towards the screen. Originally, this element serves for need of flipping the 3D text of dimension presentations.
