Obviously there was something missing in my previous mandelbox experiment… exactly, some means of transportation so you can explore the scenery!
I therefore extended the original version such that “regular” 3D stuff can be mixed with the raymarching based fractal landscape.
also I added a bit of “collision detection” so that the landscape can be moved “out of the way” when your transport gets too close..
so enjoy your ride: https://www.wothke.ch/modum/#/wright-and-bastard/sets/evoke-2016

Notice: Unfortunately Chrome seems to be the only browser that currently properly supports WEBGL_draw_buffers. (Firefox also claims to support the feature but in fact it is completely messing up the respective color attachments..
