If you are interested primarily in simulating your algorithms and do not have the time or patience to author 3D worlds, a good option would be to explore 3D sites that have these models submitted by many artists. Turbosquid has an excellent repository of these models in a variety of known 3D formats that are affordable. You would need a 3D modeling tool such as Blender(available for free) to export them into VRML for use with Simulink 3D Animation.
