In s_aaline.c, see: #define NAME(x) aa_rgba_##x #define DO_Z #include "s_aalinetemp.h" #define NAME(x) aa_general_rgba_##x #define DO_Z #define DO_ATTRIBS #include "s_aalinetemp.h" the NAME macro is used by the template code in the .h file to name the functions. > When and where the functions in s_aalinetemp.h and s_aaline.c are > called/used? Called via swrast->Line(). You could run an AA line test program in gdb, set a breakpoint on aa_rgba_line() and look at the stack trace. > Are the draw_line, draw_triangle, draw_point functions in OSMesa some > how connected with src/mesa/main/line.c or point.c? Not really. The later files just set state related to those prims. > Is it possible to take out some required functions for example > aa_rgba_line(), gl_context, etc. and compile it on my system so that I > can draw a line into the framebuffer?

I don't think that's feasible. -Brian _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
