Build, import, and interact with actors in 3D environment; access Unreal Engine® features

An actor represents an entity in the 3D environment that you can interact with or manipulate. Use the MATLAB® or Simulink® interface to build 3D models with actors in the Unreal Engine environment.

  • Associate visual representations, behaviors, and properties with actors, such as visual meshes, vehicles, lights, and annotations.

  • Define coordinate systems in which to simulate 3D actor transformations.

  • Organize actors into a hierarchical structure by defining parent-child relationships. These relationships allow child actors to inherit properties and behaviors from their parent actors, which allows you to more efficiently manage and manipulate actors within the 3D environment.

  • Control and access the actor object in the 3D environment to perform tasks such as basic 3D modeling and agent-based modeling, where you can create and simulate autonomous actor objects.

  • Build an appearance for an empty actor in the Unreal Engine environment using 3D graphic primitives and mesh data, or import 3D file formats, including FBX, STL, and URDF.

  • Simulate actors using advanced features such as the physics engine and object interaction events, like collision detection.
