The best way to practice with this software is to modify the code of the different examples the package comes with (they are placed in /var/www/html/3dhop-3.0/examples).
For people that wants to help ArcheOS development and test this package, I upload it here. Soon we will prepare also 32-bit packages.
I hope this package will be useful! Merry Christmas and Happy new year!
Marco Callieri (Visual Computing Lab - CNR-ISTI) notified me that Nexus and 3DHOP are under development right in these days, so there will be probably a new version in a short time. As soon as there will be changes, I will update the packages with the new functionalities.
