An abstract graphical data type (AGDT) is an extension of an abstract data type for computer graphics. AGDTs provide the advantages of the ADTs with facilities to build graphical objects in a structured way. Formally, an AGDT may be defined as a "class of graphical objects whose logical behavior is defined by a set of graphical characteristics and a set of graphical operations". AGDTs were introduced in 1979 by Nadia Magnenat Thalmann and Daniel Thalmann. The most important tool in this graphical extension is the 3-D graphical type—the figure type. The syntax is described in Figure 2. The word "figure" is a keyword. The formal parameter section, the declaration, and the body are similar to the corresponding elements in a procedure. To define a figure type, one must 1. * find the characteristics of the figure, which become the parameters; 2. * find the algorithm that allows the user to build the figure with the help of the parameters. To build the figures, typical graphical statements should be used like: moveabs, moverel, lineabs, and linerel to draw vectors, and include to define an existing figure as part of a new one. For example, a pyramid with four vertices can be defined as type PYRAMID = figure (A, B, C, D: VECTOR);beginmoveabs A; lineabs B, C, A, D, C;moveabs B; lineabs Dend; A tree can be defined by 3-D graphical types as type TREE = figure (var BRANCHES: TEXT; NBRANCHES: INTEGER;POSITION: VECTOR; HEIGHT, LENGTH:REAL); where BRANCHES is a file of kinds of branches, NBRANCHES is the number of branches, POSITION is the position of the trunk, HEIGHT is the height of the trunk, and LENGTH is thelength of the branches. A forest of trees can be defined as var FOREST: array [1..NBTREES] of TREE Abstract graphical types have been implemented as an extension of the PASCAL programming language called MIRA-3D. (Wikipedia).

The two types of binary operations discussed in this video are commutative and associative. We saw them in the previous video and here we define them specifically so that we can build on our repertoire to use in proofs. Remember, it is by filling up our toolbox with these definitions that
