In projective geometry every point in 2D +is represented by a three-dimensional vector and every point in 3D is +represented by a four-dimensional vector. This has the following advantages: + +There are points at infinity that can be treated just like normal points. +- Projective transformations are described by matrices but they can also + represent affine transformations i.e. also translations. +- Every two lines have a unique point of intersection if they lie in the same + plane. Parallel lines have a point of intersection at infinity. +- Points of intersection, planes or lines through given points can be calculated + using simple cross products or tensor diagrams. +- Special complex points at infinity and cross ratios can be used to calculate + angles and to construct perpendicular geometric structures. +- Most of the computation in the library done via tensor diagrams (using + numpy.einsum). + +WWW: https://github.com/jan-mue/geometer |
