Any Quaternion VI's in LabVIEW?

[YSKIMO57]

Hello,

My application forms 3-D transformation matrix which includes rotations.

I want to convert roll-pitch-yaw angles into Quaternion, and vice versa.

Is there any Quaternion conversion VI's in LabVIEW ?

I tried, but couldn't find one in the search in the Help window.

Looking forward a good advice..

Best,

YK.

Hello,

I have the same problem. I have found some help on internet. Apparently it is implemented in this dll : microsoft.windowsmobile.directx.dll. But I could not find the dll on my computer. But it look likes very fine with some nice help on msdn forum. If someone could upload the dll it will be very nice of him. If you understand java there is a link below for explanation of use : http://www.euclideanspace.com/maths/geometry/rotations/conversions/quaternionToAngle/index.htm.
