Cloud engine

[Dark_Arkon]

The Vray Sun and sky is great, but now, is it possible to have clouds?

Thanks.

Not physical, but there are a number of different ways of achieving it here:

It works very well though, and I cant imagine physical clouds being the easiest thing to code in.

something to make clouds that are very 'volumous', if there's such a word, and interacts with sun/sky

[tom schuelke]

yes thats sometihing i wished too..

something as intuitiv and realistic as vue6 athmosperic skys, but also working with vray without difficult integrationsteps..

A built in cloud generator that interacts with the VRay sun/sky would be a nice addition to the VRay sky.

I think with the capabilities in the 3S, Fast 3S, and 2 sided shaders, a volumetric shader wouldn't be too far of a stretch. Actually, I have gotten pretty close simply using falloff maps and cloud shaped meshes.

i think to write a decent cloud engine (not procedural based like all of the existing ones) but actually voxel based clounds, its as much work as to write vray or any renderer for that matter from the ground up to what we have today. Asking for cloud engine, is really an unrealistic request.

Quoted for agreement....I'd rather have Vlado work on more actually renderer-related features :P

what like aura?

[Da_elf]

aura. what a magical word. just uttering it makes ears around the world perk up

[dbuchhofer]

i'd always sort of wanted to implement something like this http://www.gamasutra.com/features/20.../wang_01.shtml but never really found the time to play with it more info at http://niniane.org/clouds/

theres also source at GDmag, and a video on her website at http://niniane.org/clouds/CloudsInGames_NinianeWang.mpg

combined with some of the fun stuff in the other cloud/sky thread i think it could be interesting.

And all of this is running realtime in 2003.. sooo.. hey and on her site theres also links to the gmax script, and some sample cloud files to play with.

haha you funny guy

no, voxel based is not aura or fume. Its much more then that. For intance, proprietery software called storm; chris nichols would have more info on that, but it did allow them to simulate nice clouds and other smoke like effects. Cache files are enourmous though.

[percydaman]

my point was that I agreed with you, that as much as I'd like to see this sort of thing, look at the development time of aura, which in an abstract sort of way is similiar to what is being asked for.

[vlado]

Doesn't Dreamscape do this sort of thing already, specifically for clouds?

Hi,

I know it doesn't help posting about internal tools others have, but it seems pixomondo wrote some nice cloud tools for their red baron VFX. Check it out here:
