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 Open surface.

Layout

The scene contains line patterns that you can use for vehicle testing. The scene uses the world coordinate system to locate objects.

Scene Dimensions

This table provides the scene corner locations in the world coordinate system. Dimensions are in m.

Location	X	Y	Z
Scene — Bottom left	-1010.00	1010.00	0
Scene — Top right	1010.00	-1010.00	0

Recommended Starting Location

This table provides the recommended starting location for the vehicle in the world coordinate system. Dimensions are in m and deg.

Recommended Starting Location
X (m)	Y (m)	Z (m)	Roll (deg)	Pitch (deg)	Yaw (deg)
0	0	0	0	0	0

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^® 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 BlackLake.

Version History

Introduced in R2018b

R2022b: Scene rendered using RoadRunner

Starting from R2022b, the Open Surface 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.
