Found a little whirly...

[dandelO]

... in a folder I rarely look inside, forgot all about this and I don't think I posted anything about it here. Sorry about the size and crops, just thought it would be good to post before I forget it again. I think I was trying to make a little dust storm, or something.
Going to see where I can go with it now. I have another test running at the moment.

The entire fractal isn't rotating, though, it's only warping. That's a problem...

[dandelO]

I can now rotate Y of a fractal but, it's a stupid method using a shader I don't really like, I think this should be very much easier.

I spent a while looking for an answer to this in old function threads. Is there a good way to rotate fractals? It's been asked many times but everything I've tried to do with functions will only rotate the ground/space on which it sits, never the fractal pattern.
I'd like to know if there's a way to use the convert, rotate vector functions to make a simple control for rotating a PFS colour information.
I'm assuming that it's one of the many problems we always come across when trying to manipulate PFS and it just won't work. Is this the case? I'm really stumped with this one.

For now, I have a working method but I'd like to do it differently, it isn't too intuitive with the way I am using at the moment.

Another small test run here. Sorry it's a bit of a frickin' Waltzin' Matilda dalek, at the moment!

You can now see the Y rotation from the fractal. Now to match some inner warp to the rotation, good fun...

Hee-hee! Not Kansas, here I come!



Looking a wee bit better now.

It looks like a tornado, kind of

[dandelO]

Just playing at the moment. It's something I've just realised about rotating shaders so, I'll get busy with it when I can and tweak it into something more fashionable.

Are you using metaclouds? Fascinating venture, Martin, and I get the urge to keep looking at the twirling clouds, transfixed...

[Volker Harun]

This cutie grows up very fast ,-) Good stuff!
The rotation of the vector ... never thought of using in an animation! ,-)

[Walli]

now let the little tornado leave a trail ;-)

[Henry Blewer]

It sort of reminds me of the cloud creature In Star Trek TOS. The one where they meet Cochran.

Nice thread  
Did you render a big one as an image DandelO ? Curious how the details look frozen !

[j meyer]

Cool! The first one is a cutie.
Tell us more about the rotation,please.

[dandelO]

Cheers, all. It's quite basic and there isn't a blue node in sight. Everything I've tried with functions can't make the fractal rotate on the Y, I'm not sure it's possible, I'd love someone to find the way and tell me it is, though.
No meta-clouds either, just a simple layer and as for leaving a trail, making a progressive legacy is tricky, I tried it when i first played with this thing(first post) months ago, no fun.
No bigger renders, as yet. I'll get back to it later.
The rotation is from a 'shader array' node.

Hi DanielO

Looks great!

Idea: Try to ad a second tornado at the same place, with nearly the same values, but dark colored or the color of the ground and fade it out earlyer (I mean not so hight). I hope You understand.
