thanx for the example. i will take a look (i am just not in front of my computer)

thanx for the replys…

it should be perspective projection…

at the moment with the ray sop and and the normalized camera position as a vector i get ortho projection, so i have to take the fov (or focal length?) in to account to get perspective projection…
or shoot a projection ray per mesh point from the cam position…like a raytracer with a virtual screen…

(in xsi ice i would do this with the raytrace node, feeding mesh points, a direction vector and the test geo, but it would shoot rays for every point of the geo)

any hints where to start?

@jsmack would this projection direction (cam pos minus mesh points) be done in a for loop with a ray sop inside?
