Polytope : object
A reference to the polytope being visualized. As soon as the object hierarchy is properly implemented, this property becomes the regular 'parent' link.
FACET : cardinal
The facet number in the original polytope, giving the projection plane.
ZOOM : scalar
Zoom factor.
FACET_POINT : vector
The intersection point of the projection facet and the view ray.
VIEWPOINT : vector
The center point of the projection, lying outside the polytope.
INNER_POINT : vector
A point on the view ray lying inside the polytope.
TRANSFORM : matrix
Matrix of a projective transformation mapping the whole polytope into the FACET The points belonging to this facet stay fixed.
VERTICES : matrix
Coordinates in affine 3-space of the vertices which correspond to a 3-dimensional (Schlegel-) projection of a 4-polytope.
