Setup

To simulate a driving maneuver in this scene:

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. Set the enabled Scene name parameter to Straight road.

Layout

The scene uses the world coordinate system to locate objects.

The active area of the scene contains the road.

World Coordinate System

The 3D visualization environment uses a world coordinate system with axes that are fixed in the inertial reference frame.

Axis	Description
X	Forward direction of the vehicle Roll — Right-handed rotation about X-axis
Y	Extends to the right of the vehicle, parallel to the ground plane Pitch — Right-handed rotation about Y-axis
Z	Extends upwards Yaw — Left-handed rotation about Z-axis

Tips

• If you have the Vehicle Dynamics Blockset™ Interface for Unreal Engine^® 4 Projects support package, then you can modify this scene. In the Unreal Engine project file that comes with the support package, this scene is named HwStrght.

Version History

Introduced in R2018b

R2022b: Scene rendered using RoadRunner

Starting from R2022b, the Straight Road scene in the Unreal Engine 3D environment is rendered using RoadRunner. As a result, the locations of scene objects, including cones and parked vehicles, are moved from their pre-R2022b locations.
