deferred rendering/shading/lighting [release, src included]

hmm You could use an edge detection shader with a blur shader and that's rather slow. I believe in directX 10 you can use AA on render targets but I am not sure. 

[Enzi]

Yeah, I think in Dx10 it's working. Damn, I hate vista.

Unfortunately the Edge detection blur looks horrible. So no proper DR in DX9.

S.T.A.L.K.E.R looked pretty good, I believe that was DX9. My issue isn't AA anyway, it's alpha transparency Keeping a forward line is annoying.

[Enzi]

Hm, actually this thread is pretty good for my question. I want to use SSAO but want to keep the Anti Aliasing. So, I have to render the world shader to the screen and not to the render target.

Thing is, my calculation to process the SSAO texture over the world shader failed completely. Does anyone know how I can do this? I mean, AoC did it too.

edit:
Lucky me, I found something on ziggyware that did exactly what I need. Here's the code if one is interested:

// Gets the screen-space texel coord from clip-space position
float2 CalcSSTexCoord (float4 vPositionCS)
{
    float2 vSSTexCoord = vPositionCS.xy / vPositionCS.w;
    vSSTexCoord = vSSTexCoord * 0.5f + 0.5f;   
    vSSTexCoord.y = 1.0f - vSSTexCoord.y;
    vSSTexCoord += 0.5f / g_vRTDimensions;   
    return vSSTexCoord;
}   

g_vRTDimensions are of course the dimensions of the renderTarget. Sorry, if I hijacked the thread with a topic that has nothing to do with the actual DR system.

A side note on AA+RT, there's an OpenGL 1.5 extension (at least on nVidia hardware) that allows antialiasing on framebuffer objects (FBO) and that worked super well for me a year ago : EXT_framebuffer_multisample

When I came back to DX I was surprised that it was impossible to get this effect on DX9-class hardware, this worked on old GeForce FX's in OGL.

WTH? I never got 2k+ fps in any scene.

[ZaPPZion]

yea, that card has got an insane fillrate

Epic. Thanks for testing man.

[ZaPPZion]

No problem, btw it's not my computer wish it was, it's a comp of a friend of mine. He configured it to perfect use for games and 3ds max, since he uses it for his work as well.

[Enzi]

3ds max without a developer graphics card? Does he have problems with that? As far as I know there are some opengl extensions missing that 3dsmax/maya is using and so there can occur some nasty bugs. Maya is running like crap on my 8800gtx and 8800gts at work. Crap in the meaning of, slow and buggy.

[Aurora]

Im using 8800GTX and Maya 2008 here runs mad fast.

No bugs, no crashes, and even with tons of polys i can move around pretty decently.

(7 more days, then my GTX295 comes and i think Maya will run frikkin madness then hehe).

no it's really fast actually. The drivers don't have the optimization that the developer cards have (like the Quadro cards), but it's fast with the default settings. We never tested the OpenGL viewports yet, DirectX 9 is faster and less buggy for what we saw at first glance.
Anyway, we're hijacking the thread, it's about the shader, which is great:D

[AriusEso]

MAX runs like total crap on my 8500 - but then it's always been poo for me no matter what card/system I've had. I switched to Maya a long time ago and haven't looked back( though, I think Autodesk have ruined that sweet ass widget, top-right in the viewport ).
