### Rotation order in Tracking Tools

Posted:

**Tue Nov 10, 2009 3:57 pm**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
