## Combinatorics

N_FLAGS (type, ...)
Determine the number of flags of a given type. type must belong to {0,...,DIM-1}. Example: "N_FLAGS (0,3,4)" determines the entry f034 of the flag vector.
CD_INDEX
Prettily print the cd-index
FACE_LATTICE
Dump the face lattice to the standard output. The output is ordered by dimension. Each row starts with [ -k : fd-k ], where k is the co-dimension, and fd-k the number of faces (as in F_VECTOR.) The faces are represented as lists of vertex indices. They appear lexicographically sorted.
DUAL_FACE_LATTICE
Dual to FACE_LATTICE. The dual faces are represented as lists of facet indices

## Visualization

VISUAL (%Visual::Polyhedron::decorations)
Visualize a polytope as a solid object (when 2-d or 3-d), or as a Schlegel diagram (4-d).
Possible supplements: DIRECTED_GRAPH, VERTEX_COLORS, TRIANGULATION, TRIANGULATION_BOUNDARY, STEINER, MIN_MAX_FACE
VISUAL_DUAL (%Visual::Polyhedron::decorations)
Visualize the dual polytope as a solid 3-d object. The polytope must be BOUNDED and CENTERED.
Returns: Visual::Polyhedron
VISUAL_TRIANGULATION_BOUNDARY (%Visual::Polygon::decorations)
Visualize the TRIANGULATION_BOUNDARY of the polytope. Obsolete; the preferred procedure is to create a SimplicialComplex using the boundary_complex client of the application topaz and call its VISUAL method.
Returns: Visual::Polygons
makeSchlegelDiagram (%make_schlegel_params)
Create a SchlegelDiagram object.
The projection ray will join the vertex barycenters of the polytope and the projection facet.
Default zoom factor is 9/10.
Returns: SchlegelDiagram
SCHLEGEL (%Visual::Graph::decorations)
Create a Schlegel diagram and draw it.
Possible supplements: VERTEX_COLORS, DIRECTED_GRAPH, CONSTRUCTION, SOLID, TRIANGULATION_BOUNDARY, STEINER
VISUAL_GRAPH (%Visual::Graph::decorations)
Visualize the GRAPH of a polyhedron.
Possible supplements: DIRECTED_GRAPH, VERTEX_COLORS, MIN_MAX_FACE
VISUAL_DUAL_GRAPH (%Visual::Graph::decorations)
Visualize the DUAL_GRAPH of a polyhedron.
Returns: Visual::Graph
VISUAL_BOUNDED_GRAPH (%Visual::Graph::decorations)
Visualize the BOUNDED_GRAPH of a polyhedron.
Returns: Visual::Graph
VISUAL_FACE_LATTICE (%Visual::Lattice::decorations)
Visualize the HASSE_DIAGRAM of a polyhedron as a multi-layer graph.
Possible supplements: MIN_MAX_FACE
VISUAL_DUAL_FACE_LATTICE (%Visual::Lattice::decorations)
Visualize the DUAL_FACE_LATTICE of a polyhedron as a multi-layer graph.
Possible supplements: MIN_MAX_FACE
GALE (%Visual::Gale::decorations)
Generate the Gale diagram of a d-polyhedron with at most d+4 vertices.
Returns: Visual::Gale
makeSchlegelSteinerPoints (%make_schlegel_params)
Create a SchlegelDiagram object.
The projection ray will connect the Steiner points of the polytope and the projection facet.
Default zoom factor is 1/2.
Returns: SchlegelDiagram
VISUAL_VORONOI
Draw a Voronoi diagram, its dual graph and the crust. Use the interactive features of the viewer to select.
