[dundee] Re: Programming in OpenGL

[Nistur]

It's ok, like I said, I realised it wasn't that and that I was doing 
something stupid further up with regards to trying to use an 
uninitialised struct* I had a look at memset and it *was* the one I 
wanted, I was just having one of my... slow moments when nothing seemed 
to make sense.
On a different note, Lee, if you still want the OpenGL stuff I've done 
now (and it's working!) then I can set you up on our CVS on the router 
(although of course, you could do that too... :S) so you can grab what 
I've got. As it is, it's just the code from the NeHe tutorials 
(http://nehe.gamedev.net) modified slightly so it more closely resembles 
what we have as a windows test project. For reference stuff, there's the 
NeHe tutorials themselves, or if you go to the CGT learning resources 
for year 2, the OpenGL Windows stuff starts with semester 1, Tutorial 6 
and go on from that, like I said, what's there should be mirrored more 
or less by the stuff I have. There is also a copy of a reference PDF up 
there too that Matt put up that might be useful in Semester1(if you 
haven't already got it) The only problem is that currently the only 
model loader is a Milkshape model loader. I don't know if this will be a 
problem for what you wanted it for. There are other documented formats 
and model loaders, on the NeHe site I think too...

Finally, when are you free so you can fuck up our router some more? :)
