Comparison with AirSim ? #55

Open elgalu opened 4 years ago

elgalu commented 4 years ago

Hello, please forgive my ignorance. How this project compares/differs to/from https://github.com/microsoft/AirSim

nmalg commented 4 years ago

Our main focus is accurate physics simulations. AGX Dynamics, which this project depends on, is a multi-physics engine solving frictional contacts, constraints, wires/cables, hydraulics, drive lines, aero- and hydrodynamics etc. with an in-house developed direct solver. This enables users to simulate realistic systems with accurate masses and resulting forces.

This project is an interface for AGX Dynamics inside Unity with additional editor GUI, physics modelling tools, data synchronization and more. The physics simulations aside, it's quite hard to compare us with AirSim and the remaining similarities depends on what's possible to do in Unity (e.g., ML-Agents for machine learning, rendering pipeline for camera simulations etc.).

It's probably also possible to integrate AGX Dynamics in AirSim and, for example, train heavy machinery (excavators, wheel- and/or underground loaders, cranes) with improved sim2real transfer.

Thanks, is it possible with AGX solutions to run civil engineering simulations for construction sites, buildings, etc?

It depends somewhat on your expectations of the simulation. AGX Dynamics simulates all degrees of freedom in a system, so everything is possible, including the challenges of parameterization. 😉
