Archeology: along with the advent of the computer, the archeologist has obtained a new tool, computer animation. An object-model can be made comparatively quick and without any wear and tear to the artifact itself by using a 3-D digitizer. All the scenery is modeled and place together in a particular scene. Now, the archeologist has a total model of the site in the computer. A lot of things can be done to this model. The exact location of artifacts is stored in the computer and can be visualized without visiting the excavation site again.
1. By using Digital Differential Analyzer algorithm draw line segments from point (1,1) to (9,7). Ans. We see that the usual equation of the line is specified by: y = mx+c

A 2D geometric shape is rotated about a point with coordinates (1,2) by 90° in a clockwise direction. Then, the shape is scaled about the same point in the x-coordinate by 2 tim
