Hello,

I am studying calibration methods for 3D measurement systems using shadow
fringe projection. I developed a virtual 3D scanner with PovRay. Using
translucent structuration and a lamp far away from it, my program allows to
generate shadow grids projected on an object to map. I want now to improve
my projection system in a more realistic manner, using a lens between grid
and object to simulate the distortion of the grid through the optical
projection system. I think that it's perhaps not easy but i think that it
could be possible. Any help or advice is welcome.

Thank you in advance and best regards,
