4.0 Introduction to Geometric Data Structures.
In order to get a computer to deal with the physical world it
must have a data representation on which computations involving
space, time, shape, size and the appearance of things can be done. In
this chapter, a particular representation for physical objects,
images and associated entities is explained. The data structures has
been implemented as small blocks of words containing pointers and
data in the fashion usual to graphics and simulation; an introduction
to this technology can be found in Knuth. Although the latest
language of implementation is PDP-10 machine code, earlier versions
were coded in LISP and SAIL with LEAP.
