Unreal Engine Scenario Applications

Build and interact with virtual reality scenes

The Simulink® 3D Animation™ toolbox provides functionality to build, visualize, and interact with virtual reality scenes and perform agent-based modeling by using the Unreal Engine® viewer.

  • Access advanced features available in the Unreal Engine, such as collision detection, and the PhysX physics engine, and set lighting and atmospheric conditions through the MATLAB® and Simulink interfaces of the Simulink 3D Animation toolbox.

  • Algorithmically build virtual worlds using 3D assets, in different supported file formats, such as VRML, X3D, FBX, STL, DAE Collada, URDF, and SDF.

  • Use the MATLAB API to control and access all objects in the virtual scene and set visual, spatial, and other properties. You can also use this API to control other functionality, such as navigation behavior, collision events, and the video output of a camera or depth sensor attached to the object.

  • Create or delete objects as you work and independently control object instances.
