What types of graphics do you know?

In the “computer graphics” section, we study how to create new and process existing graphic files using special hardware. A large number of program classes are designed to work with such data.

The following types of graphics are distinguished:

- vector;

- raster;

- fractal;

- three-dimensional;

- symbolic.

The latter has not been used for a long time, so in this article we will focus on only four types.

Specific types of graphics determine the specifics of working with them. So, for example, working with raster graphics implies, rather, its processing rather than creation. And with vector, on the contrary, more creation than processing.

Let us consider in more detail each type of graphics.

The main element is the line. A straight line or a curve is absolutely unimportant. With the help of lines all objects of vector graphics are formed. Simple objects form complex. It turns out that all the lines are interconnected.

The properties of lines include such indicators:

- the form;

- thickness;

- Colour;

- character.

If the line is closed, then it has the property of filling. An open line has two vertices - nodes, which, in turn, have their own properties.

Here, unlike the previous view, the main element is the point. For a screen image, a pixel. It has color and placement properties.

Disadvantages of bitmap images :

- take up a lot of space in the computer's memory;

- it is impossible to enlarge the picture for a better view of the elements.

An image in a fractal graphic represents several interconnected identical elements. Special algorithms or formulas help to build such drawings. Image modification is possible when replacing numbers in algorithms or parameters in formulas.

4. Three-dimensional

Studying the types of graphics, you should definitely pay attention to the following concepts:

All types of graphics have their advantages and disadvantages. But, despite this, for each of them today has its own scope. For raster graphics, this is restoration of photographs, for example, and for vector graphics, the creation of advertising banners. Perhaps in the near future the world will become aware of a new type of computer graphics. Who knows?
