Pointstream from Arius3D is already doing this.

Check it out at

What application are you thinking about? I am
sure the people at Arius3D would like to hear
from you.

Subject: Point cloud data from rendering

Hello all,

Does anyone know if it is possible to create point cloud data from a
rendering or renderable image. My thinking is to create a "virual scanner"
add in to a render engine, create good point cloud data of a surface form
and reverse engineer it using Geomagic, Rapidform or the like. It occurs to
me that a render engine must know where the "surface" of model is and as
rendering is more forgiving and more pervasive than solid modeling it would
be of tremendous benefit to be able to generate .stl from a render type of
application. The reverse enginnering applications have plently of utility
for stitching holes and filling the backside of objects that have not been
scanned and this utility could be turned to the patching of areas that were
not rendered.

Am I nuts (again!)
