Macro to build curved polygons with torus segments
As it takes 1 hr to render with focal blur and 1 area light on my old K-6
400, no radiosity was used on this scene.
Feel free to improve it at your own risk with radiosity/fotons/whatever
features. It would be nice to see.
Source code posted at p.b.s-f.


Comments?

pd.
Requires Francois Dispot's Dof.inc include file or select your render
resolution settings inside camera's statement

... beg apologizes for my english

Very nice! Shall certainly have a try at this!
(Do I see torus joints in foreground example?)

Nice image with interesting shapes !

Here's an example of a shape that can be made if you expand your macro 
to allow for tubes that follow 3D-curves:

Hi,
IMHO, it would not be easier -and powerful- using sphere_sweep with
cubic_spline interpolation?

pd. damn artifacts!
