Right, so:
"RaySAR can be run on Windows / Linux and is based on an adapted version of the
open-source ray tracer POV-Ray."

Presumably Dr. Auer isn't going to just send you off to perform some ill-defined
task with a piece of software that he (likely) knows you know nothing about.
(Although having been through several (technically 5) universities, it wouldn't
be something I'd dismiss out-of-hand ;) )

"...but i need opposite"

I'd say that what you need to do is rigorously define the task and what the
input and output need to be.  Clearly, RADAR is very much like light in that it
can travel in straight lines and bounce - so with POV-Ray, you are going to use
a lightsource and objects, and presumably a reflective surface to mimic RADAR
signals.

Draw a labeled diagram to illustrate what you need to do.

IIRC, you can use Poseray software to convert your .obj to a mesh2 object.
You might want to find a much smaller .obj file to set up a sample scene and
work out all of the details, before running it on a huge file.


(I for one, would love to have some folks from your group contribute some
practical photogrammetry resources to our community (equations, code), since I
and a few others have a long standing interest in the subject.)

We'd love to help further develop POV-Ray as a useful photogrammetry-related
software package and extend its present sphere of use!
