Simplex(char* namein, GeOb& t)
If t is a point tuple from a cartesian product affine space A×…×A, this builds a simplex for A from the tuple members. The simplex creates its own copy of the debug name given in the buffer namein.
Simplex(char* namein, ASpace& ins, GeObList& t)
Builds a simplex for the affine space ins, using the objects in the list t, after they are mapped into ins if necessary. The simplex creates its own copy of the debug name given in the buffer namein.
Simplex(Basis& f)
Used to downcast a general basis to a simplex. Only succeeds if the general basis is holding either a simplex or a frame; the latter can be automatically cast to a simplex.
