buildings
The buildings module reads C Tech’s .BLDG file and creates various 3D objects (boxes, cylinders, wedge-shapes for roofs, simple houses etc.), and provides a means for scaling the objects and/or placing the objects at user specified locations. The objects are displayed based on x, y & z coordinates supplied by the user in a .bldg file, with additional scaling option controls on the buildings user interface.
Each object is made up of 3D volumetric elements. This allows for the output of buildings to be cut or sliced to reveal a cross section through the buildings.
Selecting the “Edit Buildings” toggle will open an additional section which provides the ability to interactively create 3D buildings in your project.
Module Input Ports
- Z Scale [Number] Accepts Z Scale (vertical exaggeration) from other modules
- View [View] Connects to the viewer to allow interactive building creation.
Module Output Ports
- Z Scale [Number] Outputs Z Scale (vertical exaggeration) to other modules
- Output [Field] Outputs the buildings as a field which can be sliced, cut or further subsetted.
- Output Object [Renderable]: Outputs to the viewer
Properties and Parameters
The Properties window is arranged in the following groups of parameters:
- Properties controls Z Scale and file input and output
- Default Building Settings: Defines the default values when a building is interactive created
- Building Settings: Shows the parameters for all buildings.
Sample Buildings File Below is an example buildings file. Note that the last 4 columns are optional and contain RGB color values (three numbers from zero to 1.0) and/or a building ID number that can be used for coloring. If only color values are supplied (3 numbers) the ID is automatically determined by the row number. If four numbers are provided it is assumed that the last one is the ID. If only one number is provided it is the ID.
