Dear colleagues,

I recently have updated some pages in the Theoretical Foundation section of
the Kwon3D Motion Analysis Web (http://kwon3d.com) and here are the details
for your info:

1. Moved pages:

* Orientation Angles: from Axis Transformation (Vol I) to Joint
Kinematics (Vol II)
* Helical (Screw) Axis: from Axis Transformation (Vol I) to Joint
Kinematics (Vol II)
The URL of this page has been changed. Please update your link.

I am teaching the Advanced Kinematics and Kinetics course this
semester and realized that this is a better grouping of the topics.

2. New page:

* Vol II > Joint Kinematics > Joint Center: Functional Method

3. Page updates

* Vol II > Camera Calibration > DLT Method
The equations were all updated.
* Vol II > Camera Calibration > Least Square Method
The equations were all updated.
* Vol II > Joint Kinematics > Joint Center: Functional Method
The Newton's method was expanded to multiple markers.
A simple linear method suggested by Dr. Yong-San Yoon was added.
(Four algorithms have been tested (HU Gamage & Lasenby, Newton's
method, Downhill Simplex, and Simple linear method) so far and they all work
well.)
* Vol II > Joint Kinematics > Helical (Screw) Axis
The equations were generally simplified and updated.
The issue in computing unique helical axis position was addressed.
The relationship between the helical rotation matrix and the
transformation matrices of the moving reference frames was added.

The website for the Advanced Kinematics and Kinetics course that I teach
this semester here at TWU can be found at
http://venus.twu.edu/~f_2kwon/6113/01/. The slides are on the web.

I appreciate all the input provided in developing these pages.

Cheers,

Young-Hoo
