Thanks for confirming the "hack" :-). I thought I was going crayz.

I never worked with mesh cameras (as you may have noticed). I'm capable to
easily create a surface in CAD that is based on the Wikipedia math formulas. I
end up with a special "lens" geometry, that is always perpendicular to the
resulting beam (For perspective projection that would be a perfect sphere).
Unfortunately, I feel like this is not helping at all, becasue I need a mesh
generated in the way that there is a triangle per pixel, right? I can't simply
export and convert my CAD "lens" and use it. Please confirm.

PS: Jaime, thanks by the way for your very interesting website. Im sure I will
return to it many times in the years to come.
