# @topic category objects/any/Visualization
# Drawable primitives and arrangements thereof.
# Objects of this family are created on the fly when a visualization of a `big' object is being prepared.
# They are generic in the sense that they don't carry any attributes specific for selected/preferred
# visualization tool.

# @topic category any/Visualization
# These +++ are for visualization.

# @topic category any/Internal
# These +++ are for internal use only. You can safely ignore them.

# @topic category properties/any/Input property
# These properties are for input only. They allow redundant information.

# @topic category any/Backward compatibility
# These +++ are provided for backward compatibility with older versions of polymake only. They should not be used in new code.

# @topic category any/Utilities
# Miscellaneous +++.

# @topic category any/Other
# Special purpose +++.


# @topic category any/Combinatorics
# These +++ capture combinatorial information of the object. 
# Combinatorial properties only depend on combinatorial data of the object like, e.g., the face lattice.

# @topic category any/Symmetry
# These +++ capture information of the object that is concerned with the action of permutation groups.

# @topic category methods/any/Topology
# The following methods compute topological invariants.

# @topic category functions/any/Topology
# The following functions compute topological invariants.

# @topic category any/Topology
# The following +++ are topological invariants.

# @topic category any/Geometry
# These +++ capture geometric information of the object. 
# Geometric properties depend on geometric information of the object, like, e.g., vertices or facets.
