How to import STL files to Unity3D?

[MartinBischoff]

Currently UrdfImporter only supports the import of .dea (Collada) files.

URDF also supports STL, whereas Unity3D does not (without plugins).

How shall we realize the STL import in UrdfImporter? I see the following options:

• implement an own STL Importer
• include existing open source STL importer (e.g. https://github.com/karl-/pb_Stl)
• refer to an exisitng importer assets from Unity3D Asset Store (e.g. https://www.assetstore.unity3d.com/en/#!/content/3397). I haven't found a free one there yet.
• give users the advice to convert all stl meshes to dae before importing (http://lmgtfy.com/?q=stl+dae+converter)

We relalized STL import in commit https://github.com/siemens/ros-sharp/commit/5c613ed0706dcfb4a453234282be4a9068349064 We used option 1 taking open source STL importers as areference.
