RotationViewer()

Simple tool to visualize multiple consecutative 3D rotations via animation

Problem:
Dealing with multiple 3D rotations is usally confusing and difficult to figure out. Specially consicative rotations about intrinsic (relative) and extrinsic (static) refrence coordinates are tricky.

Solution:

I have develepoed a simple Matlab GUI application to visualize those rotations in the form of animation and give rotation matrix corresponding to the final orientation.

How to use: Simply specify the following 3 inputs in the GUI

1. Rotation type:
-> Relative - successive rotations would be carried out about the axes of the newly rotated coordinate system. This kind of rotation are sometimes called intrinsic rotations.
-> Static - successive rotations are carried about the axes of a fixed coordinate system. These rotations are sometimes called extrinsic rotations.

2. Rotation angles: - here you just put rotation angles in degrees separated by space.

3. Rotation Axis: Here the axsi about which rotations are done should be specified as space separated x y or z.

Eg: To rotate 30 deg about x, and then 20 deg about the new y and -45 deg about the new z, you need the following inputs
Rotation Angles: 30 20 -45
Rotation Axis: x y z

NB: The number of rotation angles and rotation axis are not limited except that they should be of equal length.
