M$ shows G800... in DX9 demos...

Umh..that video is pretty bad, but it doesn't show any acceptable framerate

FC's rotozoomer was the worst part of that demo, a low precision unmipmapped point filtered mess

ciao,
Marco

 

nAo: well, the year was also 1992 so what else you expect? 386 was a glorious thing and some rich ppl might have mighty 486 machine, but 286 wasn't rare either.

(btw, 2nd reality runs pretty well on 286 10Mhz with 287 on machine with MCA bus.)

nAo: and watch that demo!! it really something pretty cool.

 

Re: It was done in Hardware

Hi Rags,

Whoop, didn't realise there was a soundtrack with the movie (office PC . . .). I stand corrected.

OK, anybody in for a G800 speculation session?

It's nothing too exciting, goes something like this:

FA? - Toggle Text Display
L?? - Dynamic Tessellation (on)
C? - Tessellation Factor (320:1) (not sure about these numbers)
?? - Displacement Scale (1.30:1) (not sure about these numbers either)
YA? - Displacement Interpolation Type (linear)
TA? - Sun Angle 135,000000 degrees
Z/X - Sun Light Factor 1.000
C/V - Sky Light Factor 1,000
1/2 - Toggle Terrain & Sky Radiance Texture (on)
3/4 - Toggle Detail Color & Detail Horizon Map Texture (off) (could be "on" as well...)
5/6 - Toggle Normal Map & Horizon Map Texture (on)
7/8 - Toggle Clouds Texture (on)
W?S - Fill Mode (solid)
R?? - Fog (enabled)

 

I really don't see what should be so hard in having Disp map on SW,
I use it all the time... it just calculate the new position of the vextex once.
I even use to run an .avi file for disp map, 256*256, on a 40*40 patch, no
problem.

 

Listen to the video again:
"version pixel shader ... and displacing mapping ... and the Matrox displacing mapping hardware"

Well, was it done using some Matrox hardware partially or totally?

The key is the "version pixel shader". What is the current Matrox hardware supporting pixel shader? None right?

edited: Looks like it was a 1024x768 pixel shader with displacing mapping presentation. The totally done by Matrox hardware looks more plausible 8)

 

From www.matroxusers.com

Matrox had used the software emulation before with a unanounced card.
Two things:
- It was too slow, then probably it is not the same software emulation.
- They used an announced card, maybe they are using another announced card this time too 8)

Is it may layman´s eyes or the pics look antialiased and with some nice lighting effect?

Parhelia will have displacement mapping demo on CD.
From MURC:

 

Edit: pic removed, since it's irrelevant now.

 

This japanese articles states:
In GDC 2002, MS demonstrated displacement mapping demo with Software Emulation.
Not Matrox Hardware.

 

It probably was Parhelia with westwood demo. See this video: http://www.bp6.com/~davo/west_stud_terr.avi
Looks the same.
