This year I ported the 3D Object Converter for AmigaOS 3.x / 4.x under MorphOS and AROS i386:

It is a powerful 3D polygon model translation and interactive viewing shareware tool that allows arbitrary 3D model data to be imported from external sources, exported to various industry standard 3D file formats.

The program supports 943 file formats.

System requirements:
- TCP/IP Stack (Internet connection for the web updater)
