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
