This is for visualizing the Euler Angles and better understanding of it

File Information
Description

You can input the angles and the axis about which the co-ordiante has to be rotated to visualize the rotation and orientation.

you will have full control of what elements to be shown in screen, like path,plane of rotation,initial co-ordinate frame,etc

Description in short: : An Educating tool.

Files:
Understanding_Euler_Angles.m -- Main program

arrow3d.m -- Function to generate the 3d arrow

Rotations.m -- Computes the orientation of the reference frames and plots it.

Revolve.m -- Function to produce axisymmetric surfaces

Extrude.m -- Function to produce surface s by extruding a 2-d shape.

Cylinder.m -- Function to create a cylinder with closed facesof required radius.

Cone.m -- Function to generate cone.

If the repeated rotations are not allowed, such as common ZXZ (313), this tool is only half way done. It doesn't deserve any 5 stars ranking! Any technical difficulty ??

Very good tool for Eular Angles illustration with comments. Adding a readme.txt in the set would be appreciated.

Thanks you !

I am kind of new to this.and was wondering if you could provide some steps as how to run the programs. coz wen i run the Euler_Angles/Understanding_Euler_Angles.m file it gives an error and does not pop up any GUI.
Thank you

Good illustration to understand Euler angles

Thank you very much, I can understand the rotatation convention now. In class I couldn't "see" the rotations because of the 2-D ambiguity of the 3-D axis diagram.

Nice visualization. However, I am not sure why you do not allow repeated rotations. In moving axes of rotations (sometimes called "general convention") it is common to rotate about z, then x, then z again.

Very well done, very nice gui and demonstration or Euler rotation.

That is a terrific effort and it is working fine on my comp

This code seems to generate errors in matlab for me (using Matlab R14SP1 and the required screen resolution.) The first time I tried it, page after page of errors appeared, then Matlab crashed. The second time, after restarting matlab, it still generated those errors, but did not crash. It clears the command window however, so I lose the errors to identify the failure.

Beyond those major errors, Understanding_Euler_Angles could use more comments about what it does. For example, a ReadMe file would be very useful.

nice educational tool
