Quaternion problem with VRPN and virtools
Posted: Wed Sep 14, 2011 11:55 pm
Hi!
When trying to receive the position and quaternion information using VRPN and the building blocks Virtools provides, I run into the following problem. The position data is transferred ok, but the quaternion not. When testing with a separate program the data from the VRPN looks ok, but is not ok in Virtools. When trying to use the quaternion, either only 0's or 1 or -1 are given or some strange out of range information is given. I tried to calibrate it in different ways, but no luck. Do I need to convert or modify the quaternion from VRPN somehow so that Virtools understands the information? Any help is appreciated.
