3D Math Question

Blitz3D Forums/Blitz3D Programming/3D Math Question

A question to the 3D Gurus out there:

When I give you the camera rotation and position, a pixels 2D screen-coordinate and the distance from the camera to the picked surface that lies under that pixel, is it possible to calculate the 3D Coordinate of that position where the surface was picked? (of course without to use Linepicks)
