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.
Constructor & Destructor Documentation
◆ OpenGl_Flipper()
