fractal? tunnel how to(dreamchild, lair, etc)

category: general [glöplog]
 
Can somebody explain to me(or give me a link)how to create those random tunnels with multiple branches we saw in Dreamchild(by ASD) and Lair (Conspiracy).
Thanks

google: marching cubes
yes, essentially you make a field , then put some 'chylinders' in there, and triangulate with marching cubes. In dreamchild I use a 2d marching cubes and a couple of 'blobs' to generate the cylinders, a slice a frame. Difficult to make it framerate independent but there is a way.

Good thing I'm already familiar with isosurfaces.
Thank you.

duffman: think 2d, 'extruded'

I'm actualy learning some of this at mathematical analisys... it's so hard to draw 3d functions on a 2d paper.

well then draw 3D functions on a stack of paper.

think of 2d metaballs going forward in cheese and cutting a tunnel.

This really sounds like Scene pouetry to me. ;)

vagina!
Pouetry - that's a nice word. Congratulations! I'll memorize it.

Actually "chylinder" is also a cool word: In medicine, "chylus" is another term for the lympathic fluid.

ah, medical wordplays! my favourites!!!

That's not just pouetry. As far as I remember, BoyC draws 2d metaballs with motion blur instead of generating the 3d surface via marching cubes. But the source code of his implementation is public, so you can check it yourself.
