World Settings Tool

Configure geographic position and size of environment model for data import and export

Description

The World Settings Tool is used to configure the geographic position and size of the environment model.

RoadRunner allows models to optionally be georeferenced, meaning they are built to match a particular location on the surface of the Earth.

For more information about the coordinate system used in RoadRunner, refer to Coordinate Space and Georeferencing.

Open the World Settings Tool

On the RoadRunner toolbar, click the World Settings Tool button:

Examples

Specify an Initial Latitude/Longitude Origin for the Scene

  1. Click the World Settings Tool button.

  2. Enter the desired latitude and longitude that you want to use as the origin of the scene in the World Origin section of the Attributes pane.

  3. Click the Apply World Changes button on the Attributes pane.

Clear the Geographic Position

  1. Click the World Settings Tool button.

  2. Press the Clear World Projection button in the Attributes pane.

  3. A warning dialog appears, saying that clearing the projection invalidates imported GIS files. To proceed, press the Clear button.

Center the Geographic Position on an Existing GIS File

  1. Click the World Settings Tool button.

  2. Click the GIS file you want to center the projection on.

  3. Press the Center World on Selected button in the Attributes pane.

  4. Press the Apply World Changes button in the Attributes pane.

  5. A dialog box appears, asking if you want to just change the world projection (the Only Change Projection button) or if you want to transform the model to the new projection (the Transform Scene button). See the note on changing world settings to determine the appropriate action and click the appropriate button.

Change the Origin of the Environment to a Specific Latitude/Longitude

  1. Click the World Settings Tool button.

  2. Enter the desired latitude and longitude that you want to use as the origin of the scene in the World Origin section of the Attributes pane.

  3. Click the Apply World Changes button on the Attributes pane.

  4. A dialog appears, asking if you want to just change the world projection (the Only Change Projection button) or if you want to transform the model to the new projection (the Transform Scene button). See the note on changing world settings to determine the appropriate action and press the appropriate button.

Alternatively, follow these steps:

  1. Click the World Settings Tool button. Locate the green circular mark indicating the World Origin.

  2. Click and drag the World Origin mark to the desired new origin position.

  3. Click the Apply World Changes button on the Attributes pane.

  4. A dialog appears, asking if you want to just change the world projection (the Only Change Projection button) or if you want to transform the model to the new projection (the Transform Scene button). See the note on changing world settings to determine the appropriate action and press the appropriate button.

Note

To transform a scene, you have two options:

  • Only Change Projection — Use this option if you want to change the origin without moving any scene objects. This changes the lat/long locations of the objects but preserves their local (XY) coordinates.

  • Transform Scene — Use this option if you want to change the origin and move objects to preserve their location on the earth. This changes the local (XY) coordinates of the objects but preserves their geographic (lat/long) coordinates.

Change the Workspace Size and Location

  1. Click the World Settings Tool button.

  2. Enter the desired workspace parameters (Center and Extents) on the Attributes pane.

Alternatively, follow these steps:

  1. Click and drag inside the blue World Origin box in the scene editing canvas to move the center of the workspace.

  2. Click and drag the edges or corners of the blue World Origin box to change the dimensions of the workspace.

  3. Click the Apply World Changes button on the Attributes pane.

Note

Changing the workspace does not remove or modify any data in the scene. When working with large GIS files, it can be useful to shrink the workspace to view only the portion of the file you want to view at a given time. However, remember to increase the workspace size again before exporting.
