3D Fractal in After Effects?

I’ve been experimenting with a technique that uses a series of AE expressions that allow me to create sort of a 3D fractal.

It took about a minute to render this at this resolution.

The basic gist:

1. Create a layer with a fractal noise and set the layer to SCREEN

2. Offset the multiple copies of that layer in Z space

3. Offset the evolution for each layer based on the Z position

In other words, make the first layer have an evolution of 0 degrees, the second 5, the third 10, the fourth 15…

By offsetting the fractal evolution slightly, you create instances that appear to be “connected” in Z space, thus allowing the illusion. One drawback is that you can only move around it about 120 degrees or so. Once you get to the side they either disappear or you can tell they are not connected. Certainly this effect is limited and takes a fair amount of time to render, but a fun project. Someone here suggested I do something challenging for a tutorial, perhaps I could get into this one.

Peder over at www.trapcode.com is working on a plugin for After Effects that allows you to create even more amazing 3d effects like this but with much more control, speed and fully 3 Dimensional. I was lucky enough to see a demo of it at NAB 2007. I’m looking forward to it.

EDIT: I made it in AE 7 Professional without any special plug-ins

I'm Sorry Shape Layers! I love you!
I must confess… I was never a big fan of shape layers…  we just didn’t get along.  I was used to using masks but suddenly (around AE CS3) the same mask tool began creating Red vector shapes. At first, they seemed cool enough but after accidentally adding shape layers to my comps, instead of masks, I lashed […]
Visualization Experiment and new Renders
Just playing around with a new After Effects experiment without using any 3rd Party plug-ins! I need to refine some parts of the effect but I really want to make a tutorial for it ASAP! Here are some other projects you may have missed! Using Element 3D bump mapping to create some Gold coins and […]
New Tutorial: Realistic Rain Drop FX!
In this tutorial we’ll use After Effects to create a realistic water effect without any 3rd party plug-ins! Great for adding atmosphere to a rainy scene or title. This effect is fully customization and can be used to create many cool FX! In this tutorial: Create a dripping water displacement map Simulate realistic camera DOF […]
Destruction Experiment!
What is this thing! I’ve basically combined a bunch of stuff into one experiment! I might have been inspired by the amazing planet explosions from The Force Awakens but wanted to see if I could get a cool version inside Element 3D. Few Notes on this experiment; I added smoke elements, shockwaves using CC Sphere, and even […]
