Subject: [810-088-11-SPRING] March 25th Wednesday class...

Hello Maya students,

     The entire class period on Monday was spent on a group exercise where
the 5 groups of 4 students each worked on answering some questions about
Rigging up skeletons.

     Look at the URL from the Friday before spring break:

         http://www.cs.uni.edu/~jacobson/maya/rig/blockMan313.html

     and use Google or the textbook if you bought it to try to look
up and answer:

1. What is the difference between Forward Kinematics and Inverse
   Kinematics? FK and IK are two different approaches to animating a rig,
   to animating a skeletal system.

2. Know the concepts of Hierarchy. Root, parent, child, sibling. All of
   the joints in the skeleton will be part of one hierarchy.

     Define each of the above terms.  Define and discuss the terms
                                         hierarchy, root, parent, child,
                                         sibling.

3. What is pick walking? What does the up arrow key do? What does the down
   arrow key do? What will the left arrow and the right arrow do?

4. How do you attach a piece of geometry to a skeleton you have created?

   There were some other questions asked on the blackboard but I will put
them up later on after I grade the group exercise material this evening.

   Extensive handouts were given out on Monday in class, so you will need to
get those tommorrow in class if you missed.

   We will meet in Lang 213 next MONDAY.  Lang 213 is a computer lab that
has 25 computers.

   There is no quiz tommorrow.

   Mark
