I've got 2 questions

1. " hd.get(hd.FORCE) " What kind of value is this vector from?

2. Is it possible to get (and set) the exactly newton values of a haptic divice? (phantom desktop)

I do know that there is a way by using directly the C++ GHOST SDK library.
But I would like to do it in python.

If there is no way, is it possible to implement such a library in worldViz. Maybe by a self made dll, or something like that?

Vizard reports what the Phantom is sending so you'll have to refer to their documentation to find out what units are used for the force.

Sorry, I don't have an answer for your second question. I'll check with the development team and get back to you.

Thanks for quick reply, Jeff.

I will take a look at it. I am not in a hurry. At the end of this month I need to find a solution for the problem with the second question. It would be fine if you can help me

Our Demos download page contains examples scripts for the Sensable device. Included is a script that shows how to apply a constant force effect on the device. However, the documentation does not mention whether the specified units are in newtons or not.
