Here's my try at adapting MLAA on the GPU
MLAA (MorphoLogical AntiAliasing) is a recent technique developped by Intel, that apply antialiasing on a image by using a shape recognition strategy, after edge detection has been performed o... |

Normal Mapped Screen Space Diffuse Occlusion
|
Hi,
With everyone doing SSAO these days I decided to give it a try too. I developped an extension of the algorithm, that shows how to add high frequency details to the ambient occlusion term. The technique uses 3 color components to store the occl... |

Hello everybody,
This is a project that was done after having read the paper "soft shadow volumes using penumbra wedges", and its optimized version "An optimized Soft Shadow Volume algorithm with realtime performance". It uses Direct3D as the rend... |

Thanks for the numbers !. Well the technique require a quite powerful GPU with good support for branching in the shaders.
The demo just applies to a still image.
It would be better to see it on an animated scene of course :)
you can change th... |

Thanks for the comments!
Remdul : It may help to smoothen normal map aliasing, indeed. I did not test it on an animated scene, but I guess it would. Because the edge detection uses image color only, there are a lot of "false" edges detec... |

Normal Mapped Screen Space Diffuse Occlusion
|
Fiddler : I've got a hit of 25% compared to the version without normal maps. With diffuse bleeding it becomes much slower, however. In this case, 3 RGB buffers need to be blurred, which becomes overkill ...
Tobberian : About the racoon look, maybe... |

Normal Mapped Screen Space Diffuse Occlusion

hi Martin,
Actually, each (random) ray can contribute to all 3 values (most of the time, there may be clamping).
The base vectors are defined by (HLSL) :
static float3 NMFrame[3] =
{
float3(-1.f / sqrt(6.f), 1.f / sqrt(2.f), 1.f / sqrt(3.... |

Normal Mapped Screen Space Diffuse Occlusion

hi Schrompf,
Glad you liked it :)
The effect is done at full screen resolution. The normal map is applied at the end of the blur pass (taking in account sampling for each third of the hemisphere), so a version with initial sampling at half-resolu... |

Soft shadow volumes D3D demo

thanks for the good reviews :)
51mon :
- I think many of the artifacts are caused by precision problems. Moving from a fp24 gpu like the 9800 pro to fp32 gpu like the Geforce FX already reduced artifacts a lot. Those problems particularly arise... |
