Detailed Description

The vtLevel class represents a level of a building. In the VTP's parametric building representation, each building is composed of one or more levels, and each level is defined horizontally by a number of edges (vtEdge) and vertical by a story height and number of stories. The edges contain further description of the appearance of each side of this level of the building.

Generally, a simple building will have two levels: one for the walls, and one for the roof. Some buildings may have an additional level for base, such as a cement foundation.

Each level can have its own footprint polygon, although in simple cases they will all be the same polygon.

bool vtLevel::IsUniform (   )

Returns true if this level consists of edges with identical, evenly spaced windows.
