Recursive subdivision

hello all
is it possible to recursively subdivide a surface depending on the curvature at specific parameter space on the surface?
can this be achieved without .net or c#
thanks for your replies

regards

Hi mate

sure this is possible without scripting. See there the original file came from Luis Fraguada, I used it for some experiments within facade and massing distribution studies.

stay cool, pat

Sort of...try MeshBrep with the custom mesh settings...if the surface varies a lot then the areas where more definition is needed then gets refined with further subdivision...you cn decomponse that mesh and take the face vertex index to recostruct nurbs surfaces from the mesh faces... So while it does go into further levels of subdiv, its only based on the surface geometry...though, the surface geometry could be based on other factors...

Otherwise you would need to script the recursion based on some conditions...

There is also the way that pat...ehem 'a-engine' described...subdivide a surface and then test the subsurfaces for some condition, if the condition is met, then subdivide it further. This is more 'manual' but if you only have 2-5 levels of recursion, its not so bad. Anyways, for things that will be built at our scale, too much recursion does not make much sense (this depends on many things I suppose).

thanks for the reply guys i was thinking it could be done that way you described@Pat
this one seems a bit more complex but i will try it out and see@Luis

cheers!
