Re: [Flightgear-devel] Cheaper 3D clouds?

[Wolfram Kuss]

Very interesting link!

I have to say I did nmot like the www.cs.unc.edu clouds very much, the
screenshots looked good, but the demo showed the problems.

Off course it may be the same for this paper, often clouds look better
in single screenshots than in a moving simulator, looking at them from
all sides and distances. BTW, the IMHO best screenshots come from
CFS3, see
http://www.simhq.com/simhq3/sims/interviews/cfs3/
Lets see how this will turn out to when it ships.

To look at the PDF in your link, I installed the japanese character
set for Acrobat Reader 5.0, that solved the problem I had.

The advantage of this algorithm is that the clouds can realistically
change shapes and you can probably make them match the underlying
terrain. Both is important for soaring enthusiasts.

Bye bye,
Wolfram.

[Flightgear-devel] Cheaper 3D clouds?

[Erik Hofman]

Hi,

Another approach to cliud modelling could be found here:

http://nis-lab.is.s.u-tokyo.ac.jp/~nis/abs_cgi.html#pg01

Looking at the images it has about the same looks, but seems to be 
cheaper in CPU/GPU performance:
