Indoor 3D Objects: Material Properties

Indoor vector buildings can be modeled using individual material properties for each 3D object.

All defined settings for the individual materials can be edited in the WallMan application. Material parameters, which do not affect the pre-processing of a database can be edited in ProMan as well.

Databases with the following file extension support the edit functionality for the material properties in ProMan at the moment:
  • .idb
  • .idc
  • .idi
  • .idp
  • .idw

View the material table in ProMan, which lists all materials defined for a database, by clicking Edit > Edit Material Properties. Alternatively, click Project > Edit Material Properties.

Show & modify
Open the Material Properties dialog for a selected list entry to view or edit the material parameters.
Save changes
Save the material table to a material catalogue file (.mcb) to import all or selected material definitions into other building databases.
Note: The import of material definitions from a material catalogue file is only possible in WallMan.

After selecting a material from the material list by double clicking on a list item, the Material Properties dialog opens, where the settings of the selected material can be changed.

Propagation Phenomena
The consideration of propagation phenomena (diffraction, reflection, transmission) in ray-tracing simulations can be enabled or disabled for each material individually. These settings are considered during pre-processing for the ray-tracing propagation models and therefore can not be changed in ProMan.
Note: These settings can only be changed in WallMan before pre-processing.
Thickness of the material. Only relevant for visualization and for computation with Fresnel coefficients.
Allow or prohibit simplification of polygonal objects with this material.
Note: This option can only be changed in WallMan.
Electrical Properties
Electrical properties of the material for different frequency bands.
Note: During the prediction, the properties of the nearest defined frequency is used for a material.
Color of Material
Display options for the material. The color of the objects with this material can be specified here. Besides this, objects with this material can be enabled or disabled for drawing filled or drawing at all on the display.

Select a frequency under electrical properties and click on Edit to get the frequency dependent material properties as given in the following dialog:

Frequency for the specified material properties.
Note: During the prediction, the material properties of the nearest defined frequency is used.
Parameters for empirical transmission/reflection/diffraction/scattering model
Attenuation values for the different propagation phenomena, which are used for the empirical transmission / reflection / diffraction / scattering model during ray tracing simulations.
Parameters for Fresnel Coefficients (Transmission, Reflection), GTD/UTD (Diffraction) and Deterministic Scattering
Material parameters for calculating attenuations using Fresnel coefficients (transmission, reflection), GTU / UTD (diffraction) and deterministic scattering during ray-tracing simulations.
