Damn, Ono, that is cool smoke!

You're an evil genius... without the "evil" part.

that's FANTASTIC!!!!

im wonter what else we can see from you Ono.....

Wooow!

I mean really, WOW!

Is there any chance of seeing smoke in animation?

Post by **OnoSendai** » Wed Jun 13, 2007 4:15 am

Well, you would need a program that could generate a smoke animation dataset...

Sweet!

Now we can nuke Maxwell and stuff

Could particles be translated into (smoke) dataset?

Arne:
that could work well.
I'm still thinking about how to handle the volume data formats etc...
Any more suggestions are welcome!

if each particle was treated as a spherical volume, with a user defined radius (so basically a 3d halo) with the option of modifying the density of the smoke with a sort of procedural texture, like you used in the clouds?

naturally, i have no idea of how to do that.

would be cool, if it can use fluid sim-particles, correctly:
foam, splash and such are no problem, any more, then

It would be relatively simple to read in a list of particles, and 'splat' them into a volume map, using some kind of 3d filter for each particle (e.g. gaussian, step function, etc..)
Then the volume map could be used for rendering.
Alternatively the particles could be stored in their own data structure, which might be better for sparser sets, but that would be a bit trickier to code.

you're the master! Nothing is tricky for you (except BiDir, sometimes...)

Wowee

Those tests look super!

What about using something like metaballs instead of particles?

Kram1032 · Post by **Kram1032** » Wed Jun 13, 2007 6:59 am

or both?

Very very very cool!

...O.K., that was waaaaay understating what I think about this.

FUCKING AWESOME!!!
