Hello,
To those who know OpenSCAD: is it as esay to use Processing to generate 3d models algorithmically and export them as .STL files? which libraries would you recommend for such purpose? Also, I really like OpenSCAD but its rendering is often terribly slow. Is Processing (in Java or JS) more efficient?
Thank you in advance.

Hi @amundsen,
For 3d related and geometry processing libraries, take a look at the libraries section on the Processing website:
> **[Libraries](https://processing.org/libraries/#geometry)**
>
> Extend Processing beyond graphics and images into audio, video, and communication with other devices.
For the rendering performance it depends how many objects you have in the scene and how you are drawing them…

Thanks @josephh. I have checked the libraries but I am first and foremost seeking some opinion, possibly from anyone who has used both Processing and OpenSCAD for 3D modelling.
