In the 3D world, Mandelbulb 3D

I surely am not expert in this field, there are some fantastic artists that can be found at Mandelbulb.com, it is a great site for anyone wishing to read about the creation of fractals and there are even some great tutorials listed on the site.


Some of my works over this weekend has been how to figure out to 'make' a scene using an IFS formula and then a 3Da or 4Da formula to make it work.

This one above was sort of a happy accident.
To me it appears as coral under the sea.  I even love the grains of sand on the bottom!

Then I experimented with the hexigridIFS & DodecahedronIFS from the 3Da column and got this.

Well after that surprise I turned it on its side and tried another IFS formula called
ColumnsIFS ... I remained steady with the DodecahedronIFS and added reflections to see what might happen.

Again I was very satisfied!


I imagined that this would look like some nasty leftovers that one could find in their refrigerator!

So this morning I decided to try another idea.  I used hexigridifs, Menger4 so I could use the 4D rotations, _AbsX ~ not really sure that was a big help, and then decided to see if I could 'make' a room' and use volumetric light to light it up.

The Secret Room:


And by golly, I did!  I used a rock photo for the color map and placed the light with positional light.

To understand this idea of 'creating' a floor and walls, I've decided to add more formulas to see what I could get.

The trick is the lighting and Hal Tenny has a great tutorial on the use of Volumetric Lighting here:
Lighting Tutorial by Hal Tenny.

Learning to use this kind of lighting is not for the faint hearted.  I've really had a tough time doing it properly.

But using the IFS forumlas with DEcombinate have shown me how to go further into creating some interesting artwork.


Here is the parameters for the Secret Room, if you use them please experiment and change things up.
