I have been working through the Red Book examples, and I have been
trying to get anti-aliasing working in the same fashion as shown in
Example 6.5 (aapoly.c).
In short, here are the four functions they call to enable anti-aliasing:
glBlendFunc (GL_SRC_ALPHA_SATURATE, GL_ONE);
glClearColor (0.0, 0.0, 0.0, 0.0);
Using the same technique in my program, everything works fine on screen,
but when I use OSMesa, there is no anti-aliasing, and you can see all
the triangles that compose the objects drawn on top of the shading.
Also everything is really jagged as well.
Has anybody used polygon anti-aliasing with success and are there examples?
Would the problem be my hardware for some reason (I use software
rendering with a radeon x300 on Linux 2.6.16 with Mesa 6.5 (no fglrx))?
Any clues? :-)
