Model Directly Generates a 3D Simulator

A reply mentions that when a model was tasked with directly generating a 3D multibody simulator, it successfully implemented rigid body dynamics, quaternion integration, OBB collision detection, and frictional contact. It even included hinge constraints, PD torque motors, a 12-joint quadruped controller, and could compile into WASM, rendering via WebGL into a standalone, runnable HTML simulator.

The author added that the model later utilized more 3D / IK environments and improved RL, making their job much easier.
