Is Omniverse Isaac Sim Unity under the covers?

Feels just like Unity so far. id like to know whats under the covers of Omniverse Isaac Sim.
did you somehow take unity3d and turn it into your own IDE/player for robotics simulation?

Hi Juan,

No, Issac Sim is not based on unity is built on top of Omniverse.
