Basic Elements: Planar Walls with Polygonal Shape

Indoor vector databases allow the description of each arbitrary object. To limit the complexity of the file and data format, WinProp supports only planar objects. In the indoor database, they are called walls – but such planar elements are obviously not limited to walls.

Also, tables, cupboards and all further indoor objects can be modeled with these planar elements. The elements can have an arbitrary number of corners. Round objects must be approximated with planar objects, see Figure 1. The more planar objects the better the approximation – but also the longer the computation times during the propagation analysis.
