How to compute the rotational matrix

Post by totti0820 » Thu Aug 23, 2012 1:24 am


I m using the V120Trio with tracking tool library 2.3.2 for our project and now having some issues, I hope that I could get help here:)

1. It seems that the TT_TrackableLocation function gives me the trackable position which is in left hand coordinate system (Z<0), does this affect further computation (eg, translation)?

2. TT_TrackableLocation function would give me the yaw-pitch-roll parameter, how could I convert these parameter to rotational matrix? I tried to use Rz-Ry-Rx convention but seems doesn't work.

3. TT_TrackableLocation function would also return the quaternion, how could I convert it to rotation matrix? I tried to convert but doesn't work

Thank you very much, Any help would be greatly appreciated.
