This complete project shows how to make 3D projection on a 2D surface.
It contains a 3D-projection function and example plots of a 3D trajectory and a 3D cube with a tetahedrom
on top of it (wire frame).

It graphically shows all the parameters that control the 3D projection:
the 3D-World System
the Projection System,
the Projection Plane,
the Projection Distance and
the View Direction .

You can control the observer position (through Azimuth, Elevation and Distance) and also the View Direction
(through View Azimuth, View Elevation and View Roll).

You must like math to get a complete understanding of what is going on.
Anyway, It is a good basis to begin coding your own 3D plot functions.
