I have recorded such a motion with a ball, but processed with my own plugin - http://www.youtube.com/watch?v=Wwpo4B8Ijx0

Plugin for finding maximum capture area

Hi, I have developed a plugin for MotionBuilder "VolumeCalculator" that will help to set up cameras and find better capture area.
For more information, visit the plugin page neill3d

Hope, it is helpful.

Re: Why no manual on software?

Hi Jim,

Manual will help a lot when learning Arena I guess. For example, I don't understand how to use new editing tool - point assignment (last button in editing toolbar). Could you explane please how to use it ?

Re: Different RB orientation in TT and SampleClient3d

<t>Hi Mike, I have solved a problem. <br/> <br/> I have rewritten my client to use NPTrackingTools SDK instead of NatNet. There are euler and quaternion angles both output from the trackable. Euler angles doesn't help me, as I understand because of bad singularity. After that I have tryed Eul_FromQu...

Re: Different RB orientation in TT and SampleClient3d

<t>I have a little step into a problem, I guess difference appears from Euler angles singularation, but in conversion code there are some lines for that<br/> <br/> double test = qx*qy + qz*qw;<br/> if (test > 0.499) // singularity at north pole<br/> { <br/> heading = 2.0 * atan2(qx,qw);<br/> attitud...

Different RB orientation in TT and SampleClient3d

<r>Hi,<br/> <br/> I have worked with NatNet and tryed to operate with Trackable 6DOF values. From NatNet I have received position in mm and rotation in quaternion. I convert quat to euler by means of GetEulers function from SampleClient3d. But... my values of a euler angle is differ a little from th...
