Procedural sea shell

[Maximus]

Hey guys, i was wondering how hard would it be to have some sea shell generator with ice?
Askin to ICE gurus here since i'm not this kind of expert..

i was browsing some tutorials on how this could be modeled, then i tought about ICE

http://forums.luxology.com/discussion/t ... uds&page=3

also found this very intersting video, in which the author made a procedural seashell generator in houdini, really cool



also found a script for Softimage from some time ago from Ed Harris website

http://www.edharriss.com/XSIscripts/scr ... deling.htm

But that is quite heavy and it just produces a spline wich is hard then to convert to geometry.

Any ideas?

maybe ask Daniel Brassard, i guess he is the Procedural-Nurbs-Surfaces-Man in this forum...

here's one more. Apperantly there is a '92 Siggraph paper on procedural seashell generation' out there.

Hi Maximus,

Not that hard, the ICE parametric sandbox can do it, you just have to translate the formulas into the nodes needed for the sea shell.

The sea shell topology coming with the topo pack1 does the same as the luxology website (so ICE solution it is ...). Check Torus Helical Shell and Super Torus Helical Shell.

The parametric formula plugin can also do it, I have provided the formula as a preset.

One formula can be seen here:

running some test and having fun! Thanks for those compounds again Daniel.

Workin on shading and fixing some texturing!

Nice!

Dan

[Maximus]

fixed the texturing and added some coating and iridescence! gonna play with other formulas

[fabricio.chamon]

woah, nice renders Maximus!!

[Chris_TC]

I prefer the first render, it's phenomenal!

I prefer the first render, it's phenomenal!

+ 1

I totally agree!! Very masterpiece!
Bravo Max!

what renderer?

rendertime?

[Maximus]

Its mental ray, shader is mia material + coating.
Rendertime is around 20 minutes per image, the first one has bokeh lens with dof too. Unified sampling. Render time is pretty good for the quality and the image dimension.
Considering the coating compound is very very slow.

I prefer the first one too, i was just playing with the iridescence of the coating to get some other look, but i found first one to be better-

Thanks everyone for feedback
