Yup, Nicolas did the partial porting. It should be moved to
RootLatticeRealization.
A couple notes:
- The MuPAD implementation has been used quite intensively during its
development; so the user interface should be sensible.
- In the root and weight lattice, the default coordinate system
should be given by the natural basis. I.e. in the root lattice in
rank 2, alpha_1 should have coordinates (0,1) and alpha_2 (1,0).
- There is a useful option to be added, namely for the user to
specify a bounding box specifying how far the alcoves should be drawn
- MuPAD use several backends for 2D, 3D, and latex plots. That's
probably a trick to port over for 2D, 3D plots. For latex a better
option would be to implement a generic conversion from a Sage 2D
plot to latex using pgf/tikz.
Cheers,
Nicolas
