About pose_trajectory_interpolation & Rotation representation

[YanJiaHuan]

What is the consequence if i simply remove this function and use simple point move?
Also, the data i saved, comes from the interpolation's results or the original robot poses?
About rotation representation, the current interpolation code seems to only designed for rotation vector as input? but in your paper, you use axis-angle and rotation_6d, should i change my current representation from euler to rotation vector if i want to use this schedule way point function? Or i should transform all to rotation vector to do the interpolation and transform them back to any format i like? @cheng-chi
