Hi all,

I would like to profile the rendering code of POV-Ray, and have re-built
the source under Visual C++ 6.0 OK. The problem I have is that when I
run the profiler, it only reports on functions within pvengine.obj. I
have tried running the profiler with "/EXCALL /INC povray.obj /INC
render.obj /INC BBOX.obj /INC PVENGINE.obj" as the argument, which
should select just these files for profiling. Again, in the report only
functions in pvengine.obj are reported. If I don't include the
pvengine.obj file, then the report is only a couple of lines long (other
than the header). I'd like to see how the function calls vary with
objects in the scene (my interest is in accelerating the software).

Does anyone have any experience of profiling POV-Ray with Visual C++?
Any help would be appreciated.

Thanks,

Steve

I had to compile and profile a command-line version to get it to work
properly.  I was not able to get profiling to work with the GUI version.

I suspect it's a threading thing.  Perhaps a better profiler would work.

These are my opinions.  I do NOT speak for the POV-Team.
