Curved Road

Curved road 3D environment

Since R2024a

Description

The Curved Road scene is a 3D environment of a curved highway loop. The scene is created using RoadRunner.

For information about additional scenes, see 3D Scenes for Simulation in Unreal Engine Environment.

Setup

To simulate a driving maneuver in the Curved road scene using Simulink^®:

1. Add a Simulation 3D Scene Configuration block to your Simulink model.

2. In this block, set the Scene source parameter to Default Scenes.

3. View the currently available scenes in the Scene name parameter. If the scene is not available, you must install it.

4. To install the scene:

   1. Click Install.

   2. In the Add-on installer dialog box, select the scene.

   3. Click Next and follow the prompts.

   MATLAB^® restarts after the scene is installed.

5. Select the scene name from the Scene name parameter.

To simulate in the Curved road scene using MATLAB:

1. Enter this command in MATLAB to install the scene.

   sim3d.utils.installUnrealEngineScene

2. In the Add-on installer dialog box, select the scene.

3. Click Next and follow the prompts. MATLAB restarts after the scene is installed.

4. Create a sim3d.World object.

5. Set the Scene argument to the scene name.

Layout

The scene uses the world coordinate system to locate objects.
