Templates

In WallMan, indoor walls are modeled as bordered, polygonal shaped areas which are characterised by some electromagnetic parameters which are relevant for field strength calculations. The program offers basic tools for wall creation in indoor scenarios, but without the new features, each building wall had to be entered individually. The template functionality offers a solution for this problem.

Templates consist of a certain number of walls arbitrarily placed in the database area which are combined by the template definition. A template is internally represented as a simple list of walls. In 3D space, each wall list is bordered by a cuboid. The minimum point Pmin is used as the origin for the template inherent coordinate system and will be called template origin in the following. If the mentioned cuboid is mapped on a 2D surface, it disintegrates into a rectangular shape which can be called the object’s Bounding Box.

The Indoor Lego Feature extends the WallMan indoor wall creation tools by a set of predefined templates covering structures which are frequently found in indoor databases. Lego should be understood as follows: Indoor Lego templates can be used to create whole buildings based on individual components in almost the same manner as the known LEGO toy building blocks.
