Kaleidoscope effect by vex?

Recommended Posts

Hi Everyone,

I am a beginner in houdini and mainly focus smoke simulation, I was wondering you can give some lead or where to search for be able to do an effect like this one, for me to effect this effect you build your geo and you make the kaleidoscope effect by vex ? of there is an other way, know hodini there is always an other way :blink:

I don't want like a tuto more some technical name or node who can lead to that direction, 

Thanks you !

Hi, Nick Taylor did this and shared on his patreon:

But it seems that non-patreons do not see it. The same thing is previewed here:

If you buy it, you can dig into his technique. He uses Clip SOP, if I remember correctly. So it is not entirely done in vex. You can bind your own geometry into his technique.

To get reflection symmetry in VEX try setting v@P to abs(v@P). Feeding that into an animated noise function will bring you some caleidoscope-like effects.

vector pos = abs(v@P) + set(@Time * 0.2, @Time, @Time * 0.4);
v@P += v@N * anoise(pos);

Otherwise yes, clip and mirror.

Thanks guys !

I am gonna dig the two lead you gave me and comeback with some test, houdini is an amazing software, but for a c4d artist like me, it's hard to understand all the possibilities that it offer, and the logic behind it
