NUMERICAL REPRESENTATION OF OBJECTS – REPRESENTATION OF 3D BODIES

We are familiar with everything necessary to create the image of a point or a line in digital environment, we can represent many points in 2D and in 3D. So that these sets of points projected in a design software can be transformed into somewhat suggestive images of solid objects, it is necessary to know the order in which certain points must be joined together by segments or curves, thus suggesting to the operator constructive surfaces. The information needed to build a body image is stored in a "database", having a very well-defined ordered structure of numbers and characters. The structure of the database strongly influences the speed of work, the required memory of the program, the flexibility of the program, as well as the ease of writing the program. This paper presents some common ways of organizing data to generate different types of simple representations in ascending order of complexity.
