Perhaps someone could help me with this.
I am trying to implement my own Performer application
program, and am in the process of implementing antialiasing.
In the performer manuals it implies I should set anti-aliasing on
for each geostate, and then a global switch exists, set by pfAntialias
to toggle anti-aliasing on and off. When i look at perfly however
it appears to go into the gl to turn on antialiasing, in
particular, using the code fragment
stensize(0);
acsize(0);
zbsize(0);
mssize(Multisample, 32, 1);
multisample(TRUE);
gconfig();
I think that perfly does this because Performer does not allow full access
to the RE multisampling options. Is this the case?
Anyway, I have a VTX graphics system, which, when I try to copy what perfly
has done, gives me strange results, as if the z-buffer has been turned off
,which of course it has, and the multi-sampling z-buffer has not been turned
on. Now perfly works fine, so obviously I am missing something here,
anyone any ideas?
Thanks
