I haven't seen any filters here that can produce results as clean as this...

A simple approach, with perlin noise and some offsets, to get something going.

If you curve it darker, it's kinda similar. Looks more like flames than caustics, though.

I find this quite pleasing...

Pleasing? it's quite amazing.

Not that good, but perhaps it can inspire someone to a better solution

Attempt #1, a little too rough.

I'm able to get that ribbon-like quality, but perlin noise isn't the right shape...

I thought that the caustics generator was freeware - but that was more than 2 or 3 years ago, I might be wrong though. It looks a bit like it comes fr om cell noise, but then the curves are too soft, but I would estimate a blend of 2 techniques. I guess you can't just write an email and ask "Hey guys, how did you implement that in your software..." - well you can, but I guess they won't reply.
Trying something like that in FF using a loop with a refraction component: The height is being fed by a blend of 2 perlin noises wh ere one noise blends into the other and accumulating that. Just an idea, if I have time I will try it out. |

I took some of the suggestions: 2 perlins, looped refraction, and math
 , and put them together. Getting there... |

Is there anyone else that would like to continue with this caustic challenge BUT NOT only for water, to be able to make caustic effects in general, specially for creating abstract organic patterns like the one uberzev have shown here in this threadbut did not say how it was done
This one looks beautiful, clean and well done or any other alternative variations, and maybe more abstract organic textures Anyone wants to try this challenge again? I know that as I have seen there are two ways to do this caustic effect 1 - PERLIN NOISE using Perlin noise as shown in this filter Caustics by blenderman 2 - CELLS COMPONENT using Cells component as shown in this filter Water Caustics by Indigo Ray Maybe there could be possibly another alternative way For example it would be good to know how to make something like the awesome caustics that xirja have done here Although they are beautiful and great, what I do not like is that they have too much lines in the middle and are not clean, even the smooth version. 
Smooth version 
And as these caustics are beautiful BUT not clean, I go back to the first post by uberzev
is true that none of the filters available in FF can produce results as clean as this shown by you and would be good to know if there could be really possible+ as said above Anyone wants to try this challenge again and be able to create nice and clean caustics patterns? |
