I am looking for a java library to create 3d-geometries and then convert that to .stl files so I can 3d print my object using a 3d printer.
I can imagine using a 3d-grap
Another option is: abfab3d.com This is opensourced code from Shapeways. Its is more complex and uses voxels as a base, but can convert to mesh aswell. The code is at github: abfab3d @ github
I have not tried it, but will as the openscad route is slow and difficult to integrate in a webserver, so I will try it once I have time.
There is a java library which works as a wrapper around OpenScad. The java wrapper is called JavaScad. Can be found here JavaScad. It works fine and I actually contributed to the library already.
