Library for remove hidden meshes?

[saroxonline76]

Dear All,

I am working on a radar simulator. I want simulate the beam which come
back after a reflection on an obstacle.

The obstacle is a meshed 3d model.

I have to remove the meshes that are not hit by the radar beam.
For this reason I'm looking for a library able to remove meshes hidden
by other meshes after defining source of light (antenna position).

Thanks,
Rosario

I'm sorry.

I thought that since I am looking C library this was the right group.

Thank you the same,
Rosario

I don't think you'll find a library that does this specifically. But
have a look for raytracing code. I wrote a raytracer in C++ that
calculates reflectance and shadowing of one object onto another, and
supports triangle meshes as one of the basic object types. It could
probably be adapted to what you want.
