3D Rotations

3D Space Coordinate Transformations

File Information
Description	3D Space Coordinate Transformations This folder contains 3 files (m-functions) : - t2x.m Transformation Matrix to Generalized Position Vector. - x2t.m Generalized Position Vector to Transformation Matrix. - m2m.m Mass/Inertia Tensor transformation with coordinate change. In the Generalized Position Vector the orientation can be expressed with: - unit quaternion, - Euler angles xyz (roll, pitch, and yaw), - Euler angles zyz (rotation, precession, and mutation), - unit vector and rotation angle, - Denavitt-Hartemberg parameters. Conversion between the above orientation systems can be easily achieved. The three files work independently on each other, but since they work on the same objects it is somewhat useful to keep them in the same folder. For more detailed information see the help texts of the three functions. Giampy January 2001

24 Jul 2003	Hank Jones	I changed the function names to make them more descriptive, but the coding was well-done and the documentation is clear. Thanks, Giampy!

03 Dec 2004	xhienna ver	hey can you do vector / coordinate transformation too? mmm input ax ay az then show 3d of its cartesian plot and cylindrical and spherical.. really need to know how to do it. its a homework for my class. thanks.:)

06 Feb 2007	Laurent SIMON	Errr... whatever the T matrix I enter, in roll-pitch-yaw mode, the roll is ALWAYS equal to pi/2... ?
