sim3d.environment.GeospatialConfiguration

Create 3D environment in Unreal Engine

Since R2024b

Description

The sim3d.environment.GeospatialConfiguration object implements a 3D simulation environment that is rendered by using the Unreal Engine^® from Epic Games^®. The Aerospace Blockset™ Interface for Unreal Engine Projects integrates the 3D simulation environment with Simulink^® so that you can query the world around the vehicle and virtually test perception, control, and planning algorithms.

Note

sim3d.environment.GeospatialConfiguration requires Simulink 3D Animation™.

Creation

Syntax

gsConfig = sim3d.environment.GeospatialConfiguration(Name = Value)

Description

gsConfig = sim3d.environment.GeospatialConfiguration(Name = Value) creates a sim3d.environment.GeospatialConfiguration object that defines the 3D environment in the Unreal Engine specified by options using one or more optional name-value arguments.

Output Arguments

Examples

Specify Geospatial Map as Scene

This example shows how to create a world object and specify GeospatialMap as the scene.

world = sim3d.World('Map',"/MathWorksGeoSpatial/Maps/GeoSpatialMap");

Create access token. Enter a unique token ID and token value shown on Cesium ion account. Skip this step if you already have created a token in this MATLAB session. For information on how to create an Access token in your Cesium ion account, see Visualize with Cesium. In the Create new token dialog box, enter the unique token ID string and copy and paste the access token created from the Cesium Ion page. For example, for token ID MyNewToken, enter these values.

sim3d.environment.GeospatialConfiguration.createAccessToken();

Configure the Geospatial actor using the token ID you created.

geoConfig = sim3d.environment.GeospatialConfiguration(AccessTokenID="MyNewToken",...
                                                        UseAdvancedSunSky=true,...
                                                        OriginLatitude=41.881154,...

world.createViewport();
world.run(0.02, inf);

To view the map from a preset view, left-click in the executable window and select a number from 1 to 9.

Version History

Introduced in R2024b

R2025a: sim3d.environment.GeospatialConfiguration class has two new properties

The Aerospace Blockset now offers additional support for offline dataset loading in Cesium^® to allow Air-Gap use-cases. The sim3d.environment.GeospatialConfiguration class has two new properties TilesetSource and Url.

You can use the TilesetSource property to select the value of the URL property as the source, where you can specify the file path of your offline tileset data.
