Expand description
Quaternion and axis-angle conversion utilities. Quaternion and axis-angle conversion utilities for MDL orientation data.
Binary MDL stores orientations as quaternions [w, x, y, z].
ASCII MDL uses axis-angle representation x y z angle (angle in radians).
These functions convert between the two representations.
