Natural Homogeneous Coordinates

Natural Homogeneous Coordinates. In projective geometry parallel lines intersect at a point. The point at infinity is called an ideal point. There is an ideal point for every slope. The collection of ideal points is called an ideal line . We might think of the line as a circle.
