8.2 Communicative capabilities of computer graphics

The communicative capabilities of the man-made and machine drawings can be classified as types of graphics addressed to specialists and consumers. The essence of the difference between graphics man-made and computer is that the first is made by the hands of designers who practice the philosophy of different graphic schools, with different graphic handwriting and tastes. Computer, or computer graphics, is a product of an automated process, where, despite different systems of computer devices, a universal graphic language is used with a single dictionary of visual symbols, a single system of graphic techniques and technical means. The perception of graphic information man-made and computer can be compared with reading handwritten letters and manuscripts and reading printed text of similar content. Handwritten texts reflect the individual style of writing by various authors. Reading handwritten documents for a poorly prepared person constitutes a certain difficulty. Printed text, even if it is reproduced in different typefaces, is usually perceived without any particular difficulties. The exception is the reading of printed texts in gothic or hieroglyphs. In general, the visual perception of computer graphics materials, as a means of communication between the designer and the customer, is generally understood. Using a computer, one can easily build three-dimensional models of projected objects, whose images can be viewed from any given angles and from any distance of removal. However, with all the advantages, clarity and technical rationality of the language of machine drawings, one should not completely abandon the techniques of man-made sketching, drawing and drawing, since in the process of man-made graphic work, imagination and visual and associative memory are formed and developed when the brain controls the movement of the hand and the hands develop the brain. Therefore, most of the tasks on the project graphics at the undergraduate courses are performed in the technique of man-made sketches, drawings and layouts.
