Hey there folks. I'm familiar with Apophysis and have started using Mandelbulb 3d. I'm looking for pointers on an effect similar to this:

<a href="http://www.youtube.com/v/ySf48XqBPBs&rel=1&fs=1&hd=1" target="_blank">http://www.youtube.com/v/ySf48XqBPBs&rel=1&fs=1&hd=1</a>

That is, any sort of tunnel/tube shape, not necessarily identical to the video but the same idea. Any tips towards a formula or approach would help greatly.

Hi and Welcome to the forums! There are so many combinations that have tunnels, that I don't know where to start. Just experiment and you'll find one soon. Here's a quick one with a Mandelbox and Fold Int Pwr. Fiddle with the Julia parameters if you need wider or smaller tunnels.

You can even change variables when you "cruise" through a tunnel and make it smaller while you travel

I suppose I can't just copypaste that code hmm... I'll need to watch a few more tuts to get the hang of this.

Still, thanks for the response and it's lovely that you've provided me with code to play around with.

Copy the formula and click the txt button in the open tab in M3D.
