Graphic Primitives

In previous section, we have discussed refreshing display devices and its categories which are Raster and Random Scan display devices. We have also discussed the restrictions of these display devices. In Raster Scan display device, that we have discussed in the previous section, the picture information is accumulated in the frame buffer, the thought of frame buffer conveys as the information for the image to be projected upon the screen is accumulated in the form of 0s and 1s, in respective pixels activate and deactivate on the display and this is the concept itself that contributes to the discreteness inside the picture under display. Consequently, in this section we are aimed at extend our discussion to algorithms that are responsible for real display of the geometries as line and circle upon display devices, hence there is reduces in discreteness and thus, more realistic completed image is the outcome.
