3D Engine

Configure scenes in reference applications

Description

The 3D Engine block implements the 3D simulation environment. Vehicle Dynamics Blockset™ integrates the 3D simulation environment with Simulink® so that you can query the world around the vehicle for virtually testing perception, control, and planning algorithms.

To position the vehicle in the scene:

  1. Select the position initialization method:

    • Recommended for scene — Set the initial vehicle position to values recommended for the scene

    • User-specified — Set your own initial vehicle position

  2. Click Update the model workspaces with the initial values to overwrite the initial vehicle position in the model workspaces with the applied values.
