Absolutely gorgeous! :D

A while back it occurred to me that its easy to combine distance-estimated (DE) fractal rendering with conventional 3D models.

Imagine how cool it would be flying around this kind of alien-city-scape in real-time in your browser, shooting at monsters!

I found that right now, only simple tunnels render at good-enough speed to be combined with classic 3D models and DE-based collision detection. My Ludum Dare game entry based on it:

The future will bring fast-enough fractal rendering! :D

EDIT to add: well worth looking at: http://www.shadertoy.com and http://www.fractalforums.com/images-showcase-(rate-my-fracta...

that's an awesome piece of work

For a game you could precalc the collision boxes as polygons or whatever your models use.

An instance of Fractal Lab you can play with:

When I saw these, the alien city from "Rendezvous with Rama" immediately came into my head.

These are really beautiful. Has anyone here ever delved into creating fractals with the various tools that are out there?

I don't have a strong math background, but I've always thought these things are wonderful. I'd be interested in creating my own, but I don't really know where to start (I don't want to learn the math, or write a renderer; I don't have the time).

Beautiful. Ah, the cities we wish we would have :).

I wonder though what's the state of the art for generating real-looking Western cities - i.e. the unplanned mess we live in. Some fractal base and then random outgrowths maybe?

Well, there's this: http://www.shamusyoung.com/twentysidedtale/?p=3301

And there's another project that I can't seem to find right now, lost in my bookmarks or RSS feeds.

Oh this is beautiful, nice work. Many (wow 12 already) years ago I did something related with iterated function systems and custom code. It was extremely tedious however, and used POV-Ray as renderer:

Again, lovely work.

This video from Mandelbulb Maniacs popped up on my facebook today.

I wonder if this is how we will eventually create cities using nanobots. Give them a finely tuned fractal formula, and let them go.

Who says grey goo has to be goo?

But after a nanobot fails, it just become dust that casually slides through your cell walls.

The link has a trailing slash on for me, which results in a 403, removing the trailing slash works.

Gorgeous work.

Cool. Has kind of an H.R. Geiger vibe to it.
