Hardware and Software Requirements: OpenGL
Microsoft Windows 7 and 10 contain special drivers for fast drawing three-dimensional graphics. This interface is called OpenGL and is a standard for 3D data representation.
OpenGL is itself a programming language which describes objects in the three- dimensional space with their graphic primitives (point, line, triangle). More complex bodies can be realized from those primitives.
AMan uses OpenGL. So the computer must have installed OpenGL to be able to show the 3D patterns. If problems with the 3D display occur, all (hardware) accelerations of the graphics adapter should be disabled in the system control section (display adapter settings).
