If you want to output what is going on in your sketch to Maya you will have to look into MEL Script. You'll make whatever you want in Processing, create an output file that is writing down what is happening in MEL Script, and then upload the MEL Script to Maya.

Hi asimes,

Thank you for your reply.

Maybe you have some references how to do that?

Moved from Programming Questions. Again, please, read and follow the Processing forum guidelines. Thanks.

The suggestion is (as far as I know) a hack I made up. What I did was learn the bare minimum of MEL required first. A google search pulled this up:  http://www.webdesign.org/3d-graphics/tutorials/introduction-to-mel-scripting.3389.html

There are many options, search the forum and libraries section.

There are different sunflow options, a pov-ray route and a hemesh-to-embree solution.

If you are still working in toxiclibs, know that this library has an STL export option as well.

As far as I know, in processing 2.0 you cannot export to STL format.

But, yes now I work with toxi and verletphysic.

I exported .DXF files every frame, the file number is equal to the frame number.

So now I have a bunch of files, is it possible to make animation from them. What program can it handle?
Amnon.owed maybe you have a direct link to some kind of 3D program?

For Toxiclibs STL export see: http://toxiclibs.org/docs/core/toxi/geom/mesh/STLWriter.html

I have never worked with DXF so I can't help you with that.
