Project Information

Symbolic, numeric and graphic manipulations in Non-Eclidean geometry: moebinv

The project contains two C++ libraries for symbolic, numeric and graphical manipulations in non-Euclidean (Cayley–Klein) geometries. There is a Graphical User Interface called Yaglom which allows a user to interact with these libraries by mouse clicks.
On the deeper level the first library Cycle implements basic operations on cycles (quadrics) through Fillmore-Springer-Cnops construction (FSCc). The second library Figure operates on ensembles of cycles connected by Moebius-invariant relations, e.g. orthogonality.
Both libraries are based on the Clifford algebra capacities of the GiNaC computer algebra system. Besides C++ libraries there is a Python wrapper, which can be used in interactive mode.
The core of both libraries is done for spaces with an arbitrary dimension. In addition, there are some 2D/3D-specific routines including a visualisation to PS/PDF/PNG files through Asymptote software. The source code is written in literate programming environment NoWeb.
