Rotation order in Tracking Tools

Post by mores_p »

Hello,

What is the rotation order (yaw,pitch,roll, returned from TT_TrackableLocation) assumed by the Tracking Tools to calculate final orientation?

Assuming:
- Column vector is used (vector is multiplied to the right of a matrix).
- Y = rotation matrix for yaw (rotation by "yaw" about Y-axis).
- P = rotation matrix for pitch (rotation by "pitch" about X-axis).
- R = rotation matrix for roll (rotation by "roll" about Z-axis).
Question: Is the final orientation matrix Y*R*P? If not, what is the correct order?

Thank you,
Mark

I would also like to get some more information on the rotation sequence. Is there any documentation available?

I have been trying to match raw marker data up with the rotated body data, but can't seem to get the sequence correct (or perhaps my calculations are not correct!).
