Discuss the methods for clipping the primitives
Clipping the primitives can be accomplished in two ways: Scan conversion approach: The visibility of each pixel of an item is examined in this approach, and the pixel is drawn if it is visible. In other words, we clip the item during the scan conversion process. This method is straightforward, however it does large calculations. Analytical technique: In this approach, the visible component of the primitives is determined analytically before scanning the object. This method does not execute the pixel-by-pixel verification. It shortens the computation, but it is complicated.
