Choose habitat-sim if…
- License: habitat-sim is MIT, AirSim is Other.
- Requirements: Installation can be done via Conda, pip, Docker, or building from source. Building from source requires C++ development environment setup..
- Tags unique to habitat-sim: cplusplus, robotics, sim2real, simulator.
- When you require high performance simulation of 3D environments for research in embodied artificial intelligence
When NOT to use habitat-sim
- If your project does not require the performance characteristics that Habitat-Sim provides for embodied AI research; a less specialized tool might be sufficient or more user-friendly
- When you have limited development resources since building from source requires an understanding of C++ and handling potential build issues could divert significant effort
Choose AirSim if…
- License: AirSim is Other, habitat-sim is MIT.
- Requirements: Supports Unreal Engine or Unity for simulation environments..
- Tags unique to AirSim: airsim, artificial-intelligence, autonomous-vehicles, control-systems.
- Also covers Model Training.
- When you need to simulate environments built specifically within the Unreal Engine or Unity game engines.
When NOT to use AirSim
- If your project requires simulation within a different game engine not supported by AirSim, such as CryEngine or Godot.
- When cross-platform flexibility is less of a priority compared to other specific requirements like performance optimization exclusive to one operating system.
- In cases where the development environment lacks adequate support for C++, making integration efforts more cumbersome.
