ThreeDWorld (TDW)

ThreeDWorld (TDW) is a platform for interactive multi-modal physical simulation. With TDW, users can simulate high-fidelity sensory data and physical interactions between mobile agents and objects in a wide variety of rich 3D environments.

TDW was developed primarily by Jeremy Schwartz and Esther Alter. It is now maintained by Esther Alter.

TDW is now in long-term support (LTS). TDW will receive only minor updates and bug fixes.
