Several versions of Onlabs have been developed between 2012 and 2019:
Onlabs version 0.0 under SWI-Prolog was a text-based kernel useful for testing our models.
Onlabs versions 0.1-0.3 were developed under Hive3D, a high-end 3D games engine by Eyelead Software, a computer game company based in Greece.
All Onlabs versions are computer-based except for version 0.3, which is web-based (yet experimental). One may try Onlabs version 0.3 by clicking here.
Since 2016, we have been working in Unity.
