Hi!
Hi,
I was told on fedora-devel-list about nouveau project and I would
like to help somehow ;) Although I don't have good programming skills,
renouveau tool is quite easy to use so I could try to guess how some
OpenGL commands work (examples in doc directory are really usefull, too).
I've started with glViewport() function. My question is: should I
check all possible input data including negative values?
Negative values are forbidden by the spec, so the behaviour is to issue
an error instead of sending commands. The common codebase in mesa does
that already, so we don't need to figure that out.
I tried that and it's more complicated than examples in doc/state ;-]
Please take a look at file state_NV17 from
http://fedora.pl/~gajownik/nouveau/ (it's not finished yet).
Is that normal that first glViewport() invocation is run three times
(or at least it looks like this - please see glViewport_1 file) and
subsequent ones only once? I also noticed that if I pass negative
width the second invocation of glViewport() is not run (file
glViewport_2). renouveau does not see it or it's really not executed?
It's not executed, since it's invalid.
I would also like to thank you for trying to make Open Source 3D
driver for nVidia cards! I've been waiting so long for it...
BTW Can't you move your CVS server somewhere else? Anonymous access on
sf.net does not work (actually, it works but files are outdated). I
use daily packages but it's not the same :/
Well, the advantage of sf.net is that I can give CVS access to lots of
people.
Btw, you should really give me your sf.net id so that I can add you to
the project. That way you could commit your stuff as well (and you
wouldn't have to use anonymous acces any more :)
