inspired by the incredible demo from 2001: [link]
it was quite a challenge to render this thing, in several ways:
1. the deep fractal iteration is pretty difficult to handle numerically, and getting a normal to this thing's surface (which it technically, in the limit, doesn't have) is pretty ugly.
2. it was rendered with 3 different builds of my renderer (big thanks to *Aexion for help with the rendering!), which means keeping track of lots of system variables and state files in various states of completion...
3. the builds i used to render didn't have proper state-combining functionality, so i integrated that into my latest code which was rendering a different scene by that time.
4. the temptation to stop rendering this and bake some of the newer stuff was immense!
edit: improved image quality, and it's now png
~feckt wanted to render something like this, so i hacked together a little application for him in like 5 minutes that will produce an .obj file of the sierpinski tetrahedron. it takes a commandline parameter for the recursion depth, the default is 4; interested parties can download that here: [link]

I would like to try it out : -)
can you gimme a sketch of the composition? the object is basically an icosahedron, it's just very distorted here because of a wide field of view.
This one piece, it keeps haunting me. Pulling me back. Argh.
yes, it's quite similar: instead of the centre missing from a square (and repeated on the remaining parts), it's the same process starting with a triangle.
But tiling the plane with pentagons is a different thing altogether. The largest object seems to be a 5 sided pyramid. But it doesn't look like the smaller pyramids meet each other along a line lieing in the pentagon base face.
The top triangle face looks like an isosceles triangle similar to the original but the bottom two seem like shorter scalene triangles.
Wish I could move this thing about in 3 dimensions so I could get an idea of what's going on.
you = awesome (:
Did you use a fractal program or a 3d one ?
yes, i try to make the most of my available resources
the plastic look worked out kinda ok here (glad you like it!), but i want to investigate other - more interesting - reflectance models (esp. metals) after my exams
