Marker Info

Post by Dante »

Hi,

I have a question about the Markerposition in Optitrack. I don't understand, why the position of the Marker in z direction is not the same like in the NatNet Client.

2 1
o o

.........x
.
.

3 z
o

If i click in Optitrack the Markerinfo, i get the Information that the Marker 1 & Marker 2 has in z direction a positve value, but in NatNet the value of Marker 1 and Marker 2 ist negative. Where is the problem?

Motive and it's user interface is right-handed and the data presented is all in right-handed coordinates. Some of our streamed formats stream out in left-handed coordinates currently but they will all be right-handed in the near future.

A simple rule of thumb for converting between left & right handed:

position: invert Z
quaternion orientation: invert Z and W
