Radeon HD 2900 Global Illumination

[obdeniye]

Dear mousou01,

It is my understanding that this is some sort of trick using spherical harmonics.

Additionally, this algorithm does not work if any object in the scene moves, because then the volumetric grid has to be re-computed in terms of occlusion. Is that true?

[vertibirdsoldier]

globe illumination FTW!!

[d3tach3d]

great demos but they never try to apply it to a mass scale. it can't handle it yet.

[KRIGSSV1N]

it can

[doverman2]

ohh so this is just rasterization or radiosity

[nolyspe]

P.S.: its pure rasterization.

[nolyspe]

It has nothing to do with raytracing. It's based on an irradiance probes (spherical harmonics representation) volumetric grid which is updated in real-time. When rendering a vertex, the grid is used to compute their ambient color. The reference algorithm is Nijasure / Pattanaik 2003. Only that DX10 is used for geomtric shaders which improves performance when rendering the cube maps for each probe.

[asukahan]

This only can be running under DirectX 10.1.

[tiggxtreme]

This demo can only be running under DX 10.1, but radiosity and even true raytracing has been shown possible even in DX7.

[GranulatedThingy]

excellent

[neai]

the framerate's so low it's useless

[Exestenz]

theyre running an image capture program too.

[Nuker1337]

OMFG this cant be real! this looks like real rytracing with accurateb ambient lighting! the future of gaming (th end of the rasterizer) is here! im gonna dl this ASAP b/c i have this very graphics card.

[doverman2]

ray tracing

[JKx]

you get about a max of 50 fps there ..that cant be right with that card.

[NutsandGuts]

this is raytraced global illumination, if you don't know what it is then don't post anything.

[JKx]

well ofc i know what it is ...its a lighting mix shader tester.. which my "x800 pro Agp" does about max of 70 fps out of this..so if he has a 2900 hdd i think there a problem.

[NutsandGuts]

anyway there's no way for you to test this coz it's dx10 and x800 pro agp haven't got it. so you got confused.

[JKx]

your wrong ... i have windows vista and i DO have direct X 10 .

[NutsandGuts]

YOU are wrong, even if you have windows vista and dx10 your card WILL NOT work in dx10 because it DOESN'T support it.

[JKx]

Oh stfu... you little faggot. I have ran this program I Have dx10 Dont tell me IM wrong when ive RAN it and HAVE DX10 on this fuckin computer you want me to make a fucking video with fraps?

[NutsandGuts]

FIRST don't cuss, SECOND you may have ran this program but it's not working in dx10 you n00b the first ati dx10 card is the HD 2900, i have dx9 in my old pentium 2 computer and my graphic card can barely run video dx7 games but CANNOT run dx8 nor dx9 remember we are talking about the capabilities of video, not about software.

[LeoDJ1992]

i can only run dx9 games in my new computer

[AnthonySelectaII]

Wrong, the 1st is HD2400Pro (I've the AGP version)

[NutsandGuts]

The first ATI card to support DirectX10 was the Radeon HD 2900XT, launched on may 14, 2007, YOU are wrong.

[AnthonySelectaII]

I have a HD2400, do you want to see the box and specs described inside? Search around web THEN speak

[NutsandGuts]

The first ATI card to support DirectX10 was the Radeon HD 2900XT, launched on may 14, 2007, the HD2400 was launched on june 18, 2007, again, YOU are wrong.

[AnthonySelectaII]

Sorry doc, 1 month of difference, than be calm and get a life, or look for hiring in Ati!

[gnuojoung]

Sorry man. You might have DX10 and Vista installed, but your card does not support DX10.

[Nuker1337]

not a fking shader, a photorealistic lighting technique! looks like thiss gfx is alot faster than a CPU at rendering these kind of things.

[mousou01]

Here is the demonstration.

ATI developers site

Perhaps this will not work in AMD R600,RV630,RV610 if there is not it.

I am lacking in a GS performance with the G80 system.

[SlavetoOblivion]

if that in upper left is ur fps ur rig must be shit.... ive got a 1gb 2900xt and it pwns everything

[Cazaq]

where can i get this?Dose it run on any DX10 card? (i see it's in vista)
