Virtual world rotation between two 3-D vectors
Simulink 3D Animation / Utilities
The Rotation Between 2 Vectors takes the input of two 3-by-1 vectors and returns a virtual world rotation (specified as a 4-element vector defining the axis and angle) that is needed to transform the first input vector to the second input vector.
