            # 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](https://github.com/alters-mit). It is now maintained by Esther Alter.

**TDW is now in [long-term support (LTS)](https://github.com/threedworld-mit/tdw/pull/709). TDW will receive only minor updates and bug fixes.**
