Homogenous coordinate computer graphics
WebHomogeneous coordinates have long been used in computer graphics as a convenient mathematical dev- ice for representing and transforming objects [3]. However, in spite of … WebHomogeneous coordinates in 2D space Projective geometry in 2D deals with the geometrical transformation that preserve collinearity of points, i.e. given three points on a line these three points are transformed in such a way that they remain collinear. The line may change but the transformed points are again on a line.
