Abstract
In the two-sided space, it is possible to treat oriented lines (or planes), signed angles, line segments and convex sets, which could not be treated in classical projective space, while still retaining the useful properties for geometric computations existing in classical projective space 1).
Since two-side space is also a kind of projective space, when it is necessary in this book to distinguish it from the space represented by unsigned homogeneous coordinates, the term “classical projective space” is sometimes used to refer to the latter.
