Matrix, and P is the projection matrix, the concatenated world, view, and projection can be represented by MVP.12. What is Perspective Projection? How is it different from Orthographic Projection?Orthographic projections are parallel projections that can be represented by an affine transformation. Perspective projections are not parallel projections. They are useful for artistic and technical reasons, such as verifying part fit in floor plans or representing problems in different basis for easier coordinates.In the following example, we can see for perspective projections, we are assuming the lines will meet at a point; but for orthographic, it will meet at infinite distance.Orthographic projections are commonly used in CAD drawings and technical documentations to ensure dimensions are easy to measure and to represent problems in different bases for easier understanding.13. What is the concept of Clipping in graphics?To display a large portion of a picture, scaling and translation are necessary, along with identifying the visible part. This process is challenging as some parts are partially inside, and partially visible lines or elements are omitted.Clipping is a process used to determine the visible and invisible portions of each element, with visible portions selected and invisible ones discarded. There are various types of clipping, including line and polygon clipping.14. What are vectors and how are they used in computer graphics?Vector graphics are a versatile and scalable computer graphics approach that uses mathematical equations and geometric shapes instead of pixel-based raster graphics. They have no resolution limit and retain image quality at any size.Graphic artists preserve
