I know this is a little off topic for the parent but this seems where all the DOD people are collating. I'm currently working in a research team at NJIT's CSTR. We're looking to do a lot of raytracing for a project that we are working on. We've talked to one of our friends at JHAPL and they said they use 3 internally, 2 were DOD projects and 1 was PHARLAP. He also claimed that PHARLAP was neither the fastest nor the best and that the only reason he mentioned it was that it's not export controlled and we can get our hands on it. We've started interfacing with PHARLAP and the progrnosis does not look good at all. ~12 seconds/trace, I assume because we're going from python->matlab->fortran then back from fortran->matlab->python. Does anyone here work on those other 2 raytracers? If you do work on one of those I'd love to get an email from you to see if we can get our hands on a copy of it (either from the code.mil project or via some contract for internal use only). If you'd like to know more my boss would love to do a telecon if you work on one of these. We were planning on writing our own which would be a hard endevour so if anything we'd rather just improve someone else's raytracer to include the loss calculations we need.
