View source for Homogeneous coordinates

Coordinates having the property that the object determined by them does not change if all the coordinates are multiplied by the same non-zero number. Such, for example, are [[Projective coordinates|projective coordinates]]; [[Plücker coordinates|Plücker coordinates]] and [[Pentaspherical coordinates|pentaspherical coordinates]].
