Inhomogeneous coordinates

Webb21 sep. 2024 · Homogeneous vectors look like regular vectors, and in most ways behave like them, but they differ in two key ways: They have an extra coordinate, such that a 3D vector has 4 numbers. The extra coordinate is called the w w coordinate. We define a\vec x = \vec x ax = x for all real-number a a and homogeneous vector \vec x x. WebbOne way to do this is by their two image ( e.g. pixel) coordinates ( x, y ). Another is by arbitrarily choosing some 3D point along each ray to represent the ray's direction. In …
