and something about 40bit colours

10 bit each RGB 10bit Alpha.

Darn..I can't read chinese :-?
Btw..VS2.0 and PS2.0 has slightly changed according to a previous MS power point presentation.
Temporary registers were scaled down from 16 to 12 in VS and PS both. In PS2.0 texture iterators were dual ported, now are not.
And in VS2.0 model there are 'new' registers, as loop and boolean registers. Obviously them should account for the increased flow control capabilities in this vertex shader revision.

First its Japanese not Chinese

Second, I guess maybe MS is going for the common denominator between the 3/2 possible early DX9 players. The old spec will probabily be what R300 or NV30 end up having, at least part of them.

the mountain thing with clouds/fog is very impressive IHMO.

Sorry :( I know it is Japanese, it was a freudian lapsus.

Yeah..that's the same thought I had

Can U see it? on my video player is a bit too dark to distinguish different features. I put my hope in better videos..

ciao,

Needless to say, I was rather impressed by those video clips. Thanks for the links, Idiot (no offense meant . . . ;) ). Especially video 3 . . . wow. Impressive framerate, at first glance.

Question: how did you come to the G800 conclusion, Idiot? I can't read Japanese, either, so, eh. :)

Hmm. Yes, the shader specs have changed somewhat since the RFC docs that were being distributed. I hope they'll provide the updated specs to the public, soon. Might be interesting.

Again, thanks!

He probably came to the conclusion that it was the G800 since it mentions Matrox all over the place and even has the Matrox logo on two of the videos. Unfortunately, I don't speak Japanese and the Alta Vista translantion is practically unintelligible. It does appear towards the end that someone asks if it was done on specialized hardware and the response seems to be that it was some sort of software emulation. No one around here speaks Japanese ???
 
hmmh...

Idiot: did they mention "G800" anywhere?? because G550 really is what is left from original G800 project. And this new chip was codenamed as "parhelia" while the original G800 was known as "Condor II" and was heavily based on G400 core.
 
I think you can see the "G800" in their article everywhere, even if you are using English version of IE.

......

other than that what platform did they run the "software" emulation on exactly??? The FPS is pretty good, and i won't mind if pure software rendering on my PC can achieve that kind of effect. In those cases I could just wait until the next "great" graphics chipset.....
 
Well in the last video you can hear the guy say , on matrox displacement mapping hardware

they also mention that DirectX 9 will go into beta stage this summer and will have a final release in 2003 ( i was hoping for an earlier release date )

the first video , reminds me of what JC ( no, not jesus christ ) wants to do for doom3 , very impressive for an originaly "low" polygon model

don't tell me it isn't ..


Oh yeah , more of matrox on saturday

Take a look at this report from the register:

Exclusive: Microsoft has reshuffled its roadmaps once again, and begun briefing partners and customers to expect an interim upgrade to Windows XP, dubbed XP "SE", in the first quarter of next year.

This buys more time for the Longhorn team to complete the complex task of implementing a native database file store, which Jon Honeyball first revealed to the world at The Register here, last August. In January we exclusively confirmed that the native, SQL Server-derived database would go in Longhorn, with the Blackcomb release - originally earmarked for the transition - pushed out to 2004.

XP SE will be principally a consolidation release. Candidates for inclusion are the essential .NET client-side plumbing: the common language runtime (CLR), Internet Explorer 7.0 and DirectX 9.0, and a mature Bluetooth stack. Microsoft has blown hot and cold on Bluetooth - mostly cold, actually - but with chipsets at the $5 mark, it's going to be ubiquitious in PDAs and phones by 2003.

Microsoft has more to offer to offer in the consumer department, (and DirectX is essentially a consumer technology), and as we observed this week, the Mira tablet hinges on a multi-user, RDP-enabled XP acting as the server. Windows XP consumer edition doesn't come with XP, so this is one obvious area for improvement.

Both of these things seem to tally, it also goes with earlier comments that MS want to make DX revisions a ‘bigger’ thing.

However, you have to question where this puts hardware that rumoured to be close and of DX9 spec – would they release an ‘over featured’ card with no API, or will MS do another interim DX8 release?

Nope, what Carmack does is very different - the trick is to generate bump maps for Dot3 lighting from a high poly model.
It does not affect geometry at all, so it needs a fairly detailed model for nice silhouettes (2-3000 faces IMHO).
 
don't tell me it's not similar , he'd be better off with displacement mapping , i think he should look into that .... i hate seeing features unused
 
The idea - moving geometry detail into a texture - is similar. However Carmack is most likely avoiding high poly counts in Doom3.

Using displacement would either result in incorrect shadows (when generating shadow volumes using the un-tesselated model) or cause a serious slowdown (for correct displacement mapping, poly counts would increase at least ten times). It's exactly the same reasons that stop him from using Truform AFAIK.

We need it get this info verified as I have a hard time believing a final release in 2003 with R300 coming out this summer. But something fishy is going on here alright...

Indeed. If MS do let DX9 slip into next year hardware vendors and game developers would have to shift focus to OpenGL to support the newest features. It could turn out to be a huge gamble on MS' part when you think about the fact that OpenGL has picked up pace with its own development...

As I said: Something fishy is going on alright... :eek:

yes .. but doesn't MS own opengl... :?

:D

Oh, in case you weren't making a joke:

An independent consortium, the OpenGL Architecture Review Board, guides the OpenGL specification. With broad industry support, OpenGL is the only truly open, vendor-neutral, multiplatform graphics standard.

I just know they bought a big chunk of it , but i don't know more


and , did anyone hear anything about the R300 supporting Displacement mapping ?

more is better
 
MS bought some patents from SGI for a lot of money some time ago, but what they bought never really got published. Lot of people interpreted it as though MS now owns OpenGL, but it would be right out stupid for SGI to sell the rights to it.
