In projective geometry, a plane at infinity is the hyperplane at infinity of a three dimensional projective space or to any plane contained in the hyperplane at infinity of any projective space of higher dimension. This article will be concerned solely with the three-dimensional case.
In geometry and topology, the line atinfinity is a projective line that is added to the real (affine) plane in order to give closure to, and remove the...
point atinfinity or ideal point is an idealized limiting point at the "end" of each line. In the case of an affine plane (including the Euclidean plane),...

Projective geometry can be modeled by the affine plane (or affine space) plus a line (hyperplane) "atinfinity" and then treating that line (or hyperplane)...

circular points atinfinity (also called cyclic points or isotropic points) are two special points atinfinity in the complex projective plane that are contained...
The Euclidean plane, together with its horizon, is called the real projective plane, and the horizon is sometimes called a line atinfinity. By the same...
