Computer graphics
graphic displays;
color printers have been improved and software.
TYPES OF GRAPHICS AND GRAPHIC EDITORS
Stock vector
Types of graphics
Raster
Applications of computer graphics:
1. Science Graphics
Purpose visualization (visual image) of objects of scientific research, graphic processing of calculation results.
2. Business graphics
Intended for creating illustrations often used in the work of institutions: targets, statistical summaries.
3. Design Graphics
Used by in the work of design engineers, inventors of new technology. SYSTEM AUTOMATION DESIGN (CAD)
4. Illustrative graphics
Allows a person to create arbitrary drawings. It has no production orientation. The simplest means of illustrative graphics are called graphic editors: Paint, Corel Draw.
5. Art and advertising graphics
Graphics by which commercials, computer games, cartoons, video tutorials, etc. are created. Geometrical calculations are used to create realistic images
Computer animation - this is getting moving images on the display.
Multimedia –This is a combination of high-quality images on a computer screen with sound.
Computer graphics
Comparison criterion | Raster graphics | Vector graphics |
Image Presentation Method | The image is built from a set of pixels. | The image is built using a sequence of graphic commands. |
Display of real-time objects | Drawings very accurately and in detail display real images. | The drawings, although they may be of high quality, do not reach the photographic |
Image Editing Quality | Scaling and rotation cause distortion. | Images are easily converted without loss of quality. |
Editing overlay details | Either absent or limited (Photoshop layers) | It is done elementary, because every detail is a separate object |
File size | As a rule, large, because information about each pixel is stored | As a rule, not very big, because a drawing “program” is stored |
Image building time | Minimum | With a large number of parts can be significant |
Hardware independence | The image has a fixed number of pixels. | The image is not associated with a specific number of pixels. |
Switch to alternate graphics | Transformation into a vector form is a very complicated and often unsolvable task. | To switch to raster graphics, all graphic commands are sufficient. |
