Decoding heading for a rigid body
Posted: Mon Dec 19, 2016 1:42 pm
I have created a rigid body with a center marker but i am having issues decoding its heading. Some values seem correct and others are flipped or offset by 90 degrees. Attached below is a graph of the estimated values and actual values seen.

It looks like you are experiencing Gimbal Lock. This is a common occurrence when trying to represent objects with 6 degrees of freedom in Euler rotations.
Because of occurrences like this, it is often better to utilize Quaternion rotations, which are Motive's internal default.
