Community Bonding Period

I have made two patches for OpenCL (OCL) shot code. One patch refactors the existing sph (Sphere) shot code, and the another patch implements ehy (Elliptical Hyperboloid) shot code.

Development Phase

Week 1 : 25-31 May

• Created some example .g files in mged for the primitives to be implemented this week. The Quick Reference Card proved to be quite useful.
• Do the matrix ops for ehy (Elliptical Hyperboloid) in the OpenCL side.
  • https://sourceforge.net/p/brlcad/patches/346/
• Made patch for ell (Generalized Ellipsoid) and arb8 (Arbitrary Polyhedron) OpenCL shots:
  • https://sourceforge.net/p/brlcad/patches/370/
• M1 complete.

• Tried out a bunch of code browsing tools (cscope, LXR, doxygen, etc). The NetBeans IDE seems the most promising.
