A) It is an alternative system of coordinates used in projection geometry and computer graphics.

What are homogenous coordinates, and what are they useful for? Alternative system of coordinates used in projective geometry and computer graphics O To map a point in homogenous coordinates to its corresponding euclidean coordinate we need to multiply by an essential matrix O In homogenous coordinates points are defined up to a scale (so x and wx in homogenous coordinates represent the same point in euclidean coordinates) Homogenous coordinates simplify projective transformations representing all of them by matrix multiplications
