I have written a program for segmenting fluorescent microscopy images in java. The result are triangulated meshes. I would like to export the meshes to a filetype that is compatible with blender.

My main criteria is an open API or file structure that I can use.

How can I save mesh data for multiple meshes into a file that blender can read?

I think Wavefront .obj is what you're looking for: https://en.wikipedia.org/wiki/Wavefront_.obj_file

As far as I know, Blender imports an obj file as one single object, so you may have to separate them later.

obj, fbx, 3ds, bvh, dae, ply, stl all work with blender. In my own experience OBJ works with the smallest amount of issues
