HDRI Clock
|
Hi,
This snapshot shows a close up of a digital clock.
The full article about this project can be found here.
And a video HD here
Technical features are :
- Spherical Harmonics Lighting
- Complex HDRI post processing ( glare and automatic exp... |

HDRI cloud GPU rendered
|
This screenshot shows a GPU rendered cloud.
It means that all the computing was entirely done on a Geforce 7800GTX.
With this quality it’s not in real time but it’s far more responsive than a traditional raytracer (it’s about seconds and not s... |

Esenthel Engine - DirectX 11 Tesselation
|
it's seems pretty cool but i'm disappointed with this kind of tesselation. Because your rendered model look exactly the same as the low tesselated one.
The first interesst of the tesselation for me is to smooth the sharp edge of a model ( like... |

wolf : you're right there's no anti aliasing on the video ( who was grabbed in low resolution ). I used a extern video capture program and yes the video quality isn't that great. I 'll do better next time :)
For the Spherical Harmonis I used... |

Vexator : I do a lot more :) So the Average luminance computing isn't really expensive. I doesn't profiled the whole process but you can except a least 30 fps on a Geforce 7800 with this scene in 1024x768. |

Vexator : I recursivly Downsample the Buffer until I reach the 1x1 size.
There's a great paper who explaine that : "Photographic Tone reproduction for digital Image" and also I remember of an example in the DX SDK. |

trenki : This mean that we compute the Antialiasing by hand for the Float Rendertarget. Mainly because the GeForce 7800 doesn't support Antialiasing for this kind of buffer.

HDRI cloud GPU rendered
|
Rasterman : Hum not but it will not change anything. The rendering doesn't take advantge of the 8800GTX features like the direct Rendering into a 3D volume.
On such card it's possible to have this kind of rendering in real time ( have a look on... |

HDRI cloud GPU rendered
|
apat : in theory it's very simple, I convert the Mesh into a Voxel ( it's like a Texture but in 3D ). Then I use different kind of Noise on the Voxel texture to finally render it with in raytrace ( and I had some Noise on that stage too... |

rcpedersen : I was inspired by the paper of Mark J. Harris and Anselmo Lastra “Real-time Cloud Rendering. But also by the paper of Robin Green : “Spherical Harmonic Lighting”, the excellent website of Ken Perlin and some other stuff about the lig... |
