     I have been doing a lot of work with DBW_Render lately (honors thesis), 
     and have acquired DBW 2.0 from the present keeper and author (Bill
     Baldridge).  One of the new shapes that it supports is called a 
     superquadric.  Now, I've attempted to look up info in IEEE CG&A about
     them and found out that the first issue ever to come out had an article
     about these, however, our library does not have this issue.  So, can   
     anyone point out another source for info about these (the full equation
     used for them, and how to do a ray-superquadric intersection (complete
     with normal calculation for a given point))?  Thanks in advance......
