This paper discusses an ancient system used for creating 3D movies. The
paper discusses the whole production cycle used to create a movie
for a hand. The paper explains how they modeled the hand, how the
animation was created, and a quick introduction to their MOP (Motion
Picture Language) The paper also goes to some details about how objects are 
internally represented, which includes some optimizations to make the file 
smaller by avoiding repeated vertices.

Clearly at the time of writing this paper, the idea of an interactive 3D
modeler was still some sort of science fiction. Everything was done in the
programming language MOP. And apparently, even 3D models were created by
entering vertex positions directly to the language.
As a result, they were never able to create anything larger than 1
minute, because of the teremendous overhead.

At this time, texture mapping was not invented yet, so their block diagram
doesn't address it, and it is not really mentioned in the paper at all.

In summary, the paper is really fun to read, but every single word in it
is now obsolete. So, I assume it is in the reading list as a fun read.
