3D Graphics description

3D computer graphics is a graphic that uses a three-dimensional representation of geometric data that can be processed with the help of a computer program.

3-d graphics systems give the possibility to create realistic

images. For this purpose I have to rešat the following three important problems:

-How to present the third dimension?

-How to separate from the image invisible to the observer, curves and lines

surfaces?

-How to create realistic pictures with the use of colors and

the intensity of the shadows?

The geometrical model contains descriptions of 3-d objects by

use different schemes for geometric representation of a three-dimensional physical objects.

The description contained in the geometric model is presented in the form of

image by using various techniques, depicting called display technique.

This is a free application of 3D wallpapers made with the techniques described above.

I hope you like them.
