Why we can't bundle the OpenHaptics DLL (hd.dll) with our demo

OpenHaptics is not a free API, neither for the developers nor for the end users, even if they had purchased a device from Sensable Technologies. For this reason, we cannot distribute OpenHaptics DLLs with our demos. If you are a qualified academic institution, you can obtain an academic copy (currently free of charge (2007), courtesy of Sensable Technologies) of the DLLs on the Sensable's website.
