Dear Performers,

I want to draw an object in 3D space, scaling it so as to make it appear
of a constant size when projected on screen. What scaling matrix should
I apply before drawing (let's suppose that the object has a original
size of 1) so that I get the target size on screen?

Thank you in advance,
Yuri.
