Title: Rotate PF function?
Post by: cyphyr on October 11, 2010, 05:05:37 AM

I'm sure I saw a thread about this but I cant find it. It was using a fairly simple (5 nodes?) function network to rotate a Power Fractle about its y axis. I've seen a number of threads looking for the same or similar thing but the usual answer is "hmm, you couldn't do that without functions". Can anybody remember this thread and point me to it?
:)
Cheers
Richard

I don't know how to rotate a PF, I don't think it's possible (happy to stand corrected) , but I know how to rotate a perlin 3D noise. Copy and paste the below into TG2, and play with the rotate vector node.

Cheers,
Frank

Most excellent, this will do the job VERY nicely :)
Thankyou

You can rotate almost any shader by plugging it into the shader array node, including a fractal. Set the shader array to create only one instance of the input shader and use the rotation control to rotate the input shader around Y.

This is what I needed the rotation function for.
Works a treat. I couldn't get your method to work Dandleo on a planetary scale.
Cheers guys
Richard
Ps works animated too :)
