Real-time clouds rendering
|
For those who remember, I once posted an IOTD on clouds rendering, saying I was not quite satisfied with the results. Well, here is something I'm more satisfied with ! ;)
Here are some pictures of my new interactive clouds rendering meth... |

Real-time realistic stratiform clouds shading
|
This picture show results from the paper I'm about to present at the Eurographics Workshop on Natural Phenomena, titled Real-time realistic illumination and shading of stratiform clouds.
The goal is to simulate realistic multiple scattering i... |

Do you get an error message?
No, it just exits immediately, wihtout writing anything in the console or displaying anything.

Looks really nice, but it doesn't run on my computer.
If you wanted it to be as fast as possible, why didn't you use the GPU with geometry shaders ? |

Real-time clouds rendering
|
Difficulty of reproducing depends only on me, but I myself depend on my funding, which ends pretty soon ;)
So right now I'm writing my thesis, trying to make the technique as clear as possible...
The ideas I have on speeding up... |

Noise with derivatives
|
That's very interesting. Can you show the same picture with traditional fbm to see what changes does the use of derivatives bring ? |

Real-time clouds rendering
|
I really have no worries about speed. As I said already, this is research. The demo is merely there to prove it can work, it's not production code. If it where to be put in a game, I have tons of ideas to make it several times faster. But this is the... |

Real-time clouds rendering
|
Krokhin >> It's not the same technique as SunDog's one, so we have different weaknesses. In our case, performance depends more on the fillrate (i.e. number of cloud pixels you see on the screen) than on the sky coverage. For... |

Real-time clouds rendering

Thanks for the comments.
Regarding the "too sharp" remarks, there are two answers I can give:
- The first answer is that real cumulus clouds are sharp (see example photograph). Usually, CG clouds are unnaturally too soft and blurry, because it... |

Nice images !
What is the difference between your work and the Translucent Shadow Maps of Dachsbacher & Stamminger ?

Nature in computer graphics

Working in a research team focused on computer graphics for natural objects, I could not pass this article without commenting.
If this is intended to be a survey or state of the art, there is a gaping void in the references. I won't rewrite it,... |
