22556	... I like this footnote on page 1: "[3] Futuremark's BETA program is an open, fee based cooperation program [...]" ... No wonder nVidia left the BETA program!...	Colin Fahey cpfahey@...	Jun 2, 2003 2:39 am
22557	Hi, I'm currently trying to build some procedural shaders. I'm getting some results, but getting very dissapointed overall. I have a random noise texture...	Matt Campbell mcampbel@...	Jun 2, 2003 6:22 am
22558	Actually, I think you're pretty close on the mark at the end there. I remember back in 3Dfx's days, their driver would do certain optimizations specifically...	Jimb Esser esse0027@...	Jun 2, 2003 6:53 am
22559	Hmmm... I also thought it to be a hoax, but what about the clipping planes? The shaders aren't conclusive because we can't see what the driver actually...	mitea mitea@...	Jun 2, 2003 9:31 pm
22560	Can I make an already compiled application to use Mesa if it was originally made to use OpenGL (in windows, no source)? How? ... Peace and love, Tweety ...	mitea mitea@...	Jun 2, 2003 11:26 pm

22562	Hi all, Just wondering what the deal is with loading and drawing models in OpenGL? I've got some code that loads .ASE files - all very nice, but I presume the ...	MartinGBell@...	Jun 3, 2003 11:34 am
22563	... Yes - the clip plane was clearly a cheat - because if you moved the demo eyepoint off the pre-programmed 'track', the resulting image was incorrect. ...	Stephen J Baker sjbaker@...	Jun 3, 2003 2:54 pm
22564	hmmm, are you saying ya want to speed it up a bit? use "indexed" vertex arrays for storage, and you should notice an improvement when displaying. i optomize...	Don Gunter dgunter@...	Jun 3, 2003 3:45 pm

22566	Well, I'd look to NVidia's website about triangle stripping. Depending on your needs, there are plenty of model file formats out there. Just identify what...	Kevin Bray ebray99@...	Jun 3, 2003 4:27 pm
22567	You also want to stripify your geometry. That way you not only have less to send to the GPU, you can also increase your vertex cache performance as well. ...	Kevin Bray ebray99@...	Jun 3, 2003 5:00 pm
22568	hmmm. So I'll just have to accept vertex redundancy unless I do a lot of work. ... Bah typical! Just found a whole load of DirectX utils (D3DX), including: ...	Martin Bell MartinGBell@...	Jun 3, 2003 9:03 pm
22569	=) Cheer up! Help is at hand! Here is something to stripify your models! Think about it... you can go from 3 verts per tri to 1 vert per tri + 2. ;-) ...	Kevin Bray ebray99@...	Jun 3, 2003 9:37 pm
22570	Heh. The good part of Dx is that it has functions like that. The bad part is they aren't always easy to get to work, and the docs aren't always clear on whats...	Jesse Laeuchli jesse@...	Jun 3, 2003 10:20 pm
22571	darn right! i've gotten pretty far with models... heheh my engines kinda lame so far ... dang shadows an lighting... it's still wayyyyy to slow with that...	Don Gunter dgunter@...	Jun 3, 2003 10:34 pm
22572	Hi Martin, extracting triangle strips is usually not a lot of work. The key ingredient is to deduce the connectivity of the mesh (that is, which triangles...	Christopher Dyken erikd@...	Jun 3, 2003 10:37 pm

22576	Hi all. I can recall that I read somewhere that Phong shading can be faked using texture with a ball on it. But don't know anything more about it. Can you...	Stanislav Blinov kerry@...	Jun 4, 2003 7:51 am
22577	One way to do that is to use cube mapping, look here for an explanation: http://developer.nvidia.com/view.asp?IO=cube_maps But I think that phong-shading can...	Peter Venis petervenis@...	Jun 4, 2003 10:05 am

22581	The SGIX suffix means that the extensions are experimental, i.e. the spec isn't final and can be changed. SGIS extensions are considered to have stable API ...	Lev Povalahev levp@...	Jun 4, 2003 2:41 pm

22584	SGIS and SGIX extensions are all proposed by Silicon Graphics. The 'SGIX' prefix is used to indicate that the extension is experimental, while 'SGIS' indicates...	Jonathan Putsman Jonathan.Putsman@...	Jun 4, 2003 3:50 pm
