Re: Tracking tools - Matlab
I should also note, that it is probably best to rebuild the NPTrackingTools VI library from the DLL (see comments on how to import shared library in previous posts) for each new version of the Tracking Tools software that is released.

Re: Tracking tools - Matlab
<t>Hi Drorm,<br/> <br/> I'd need to know what you've done in more detail. It is necessary to have setup your project in Tracking Tools first (with hardware key). Then close down the Tracking Tools program and open the Labview VI (TT_test.vi). When you run the VI, it should work automatically, if it ...

Re: c3d export into MB
<r>Hi Doug,<br/> <br/> We seem to be having some trouble getting this to work. In fact often things go totally crazy. It seems that if load a timeline file and then export from the first frame, that things seem to go OK. However sometimes when we export (typically when we have played through the tim...

Re: c3d export into MB
<t>I have another question regarding the C3D export.<br/> <br/> We have four trackables which track well. We then export these and load in Visual 3D. From one trial to the next, the marker names (which are numbers) change so that the same marker is called something different each time. The trackable...

Re: Help on rotation using quaternions or YPR
<t>This is how I would do it - <br/> <br/> I think that is typically easiest to use the Direction Cosine Matrix (DCM) for rotation operations. So first you need to convert quaternions to DCM -<br/> <br/> DCM = [(1-2*qy^2 - 2*qz^2) (2*qx*qy(i) - 2*qz*qw) (2*qx*qz + 2*qy*qw)<br/> (2*qx*qy + 2*qz*qw) (...

partial marker sets
Is it possible to collect only some body parts in Arena, eg. the legs or arms only? Or do you have to collect the full body marker set?

Re: Help on rotation using quaternions or YPR
I should clarify that the convention above is a ZYX rotation sequence (rotate about the Z axis first, then about the Y' axis and then about the X' axis)
