I'm visualising the motion of a rigidbody in 3D space with MATLAB and Simulink using this library which implements 6DOF equations of motion based on applied forces and moments.
I am confused though on the difference between the Euler angles and the angular position. In the picture above, I've integrated the angular rates to get the angular positions. Comparing the display to the Euler angle display I get different sets of angles. Below is what my visualization looks like:
Should I be visualizing the orientation of the block with the Euler angles or the angular position (integrated angular rates) i.e. which values are the true angles of the rigidbody in the body frame?
