Straight Road

Straight road 3D environment

Description

The Straight Road scene is a 3D environment of a straight four-lane divided highway. The scene is rendered using RoadRunner.

Setup

To simulate a driving maneuver in this scene:

Add a Simulation 3D Scene Configuration block to your Simulink^® model.
In this block, set the Scene source parameter to Default Scenes.
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

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.
