[brlcad-devel] Fwd: request for some help

[Vasco Alexandre da Silva Costa]

Hello Shailesh,
Your patch needed to be manually merged, because it had merge conflicts
with the latest version at SVN HEAD.

Other than that you can't use just any value for ID_HRT. You need to use
the value declared in "include/rt/defines.h". That produces visible output.

But there are still problems with the intersections. Depending on the view
direction the output can be completely out of whack. It is probably some
issue either with the orientation matrix/computations or with the equation
solver.

Regards,

I am attaching my patch containing the latest changes.

Also, please tell me is there a log file generated with the rt log, as I am
not being able to copy my log to ask it on the mailing list.

PS: The OpenCL equation solver hasn't been tested with polynomials over 4th
degree. So I wouldn't be surprised if there is a bug there.

Hello Sir,
I changed the ID_HRT value to the one defined in "include/rt/defines.h" but
I am still not able to get any output.
For the other errors, I am still figuring out how to use GDB.

Regards
