Thanks Dinky, here's another one (and better I think):

That's enough to hypnotize a cuttlefish smiley Now make the brightness vary over the fractal as well. These are very cool Kali!

from where does the brightness come ? from density ? or is it an animated param of yours !?

@eiffie: thanks, and good idea... I'll try to do something later

@CK: It comes from accumulated step count... the rays don't stop when passing through the fractal and as it is a surface with no volume, the results are this thin bright layers, then I use sin function to vary the intensity in time.

This one uses different approach for the volumetric rendering, and also I implemented eiffie's idea smiley

These movies are incredible!  A Beer Cup A Beer Cup A Beer Cup
Are they dynamic fractals? It looks like the small parts oscillate more quickly, but maybe you clamp the oscillation speed as I would expect more bristling of the surface otherwise.

Thanks, Tom. This are not dynamic fractals, but will post some fractally animated ones later.

Awesome.  I really need to learn to animate with fragmentarium.

Thanks SJS02 and Benesi.

In Fragmentarium declare this:

Code:
uniform float time;

Then you have to do all based on this time variable. Consider that you have to use the older non-progressive renders (like DE-Raytracer-v0.9.1.frag). For this animations I'm using my own tracer mod, and I use sin and cos function for varying parameters. I still have to work on camera animation, but maybe I'll wait for Syntopia to implement some keyframe system (he said is planning to do it in the future versions).

Thanks Tom!

I just uploaded this to Youtube, but not so good video quality:
