DESCRIPTION OF OBJECT MODELING METHODS IN AutoCAD ENVIRONMENT

Abstract

The main objective of the work is to develop a program for the construction of computer graphic models of real objects in three-dimensional space, as well as of relief perspectives of compositions in interactive mode formed by means of various objects.

For the development of the program, the following baseline data can be used:

1. the geometric description of a real object or a composition formed from several objects (i.e. shape, dimensions and mutual position of the objects);
2. as a starting point, a three-dimensional graphical model of a real object or a composition of several objects in any computer graphics system.

The choice of the first version of the baseline data is not recommended because there will be a need to repeat the development of already existing programs intended for the three- dimensional graphic modeling of objects. Therefore, we choose the second version of the baseline data. In case of selecting this option, the construction of the relief perspective graphic model of the object can be carried out by modifying the already built three- dimensional graphical model of the object. This approach is justified if the fairly high level of development of modern computer graphics and such a wide market of various computer software means intended for the automation of graphic modeling and graphic information processing are taken into account.
