Choose AirSim if…
- AirSim is primarily C++; hold is Python.
- License: AirSim is Other, hold is MIT.
- Requirements: Supports Unreal Engine or Unity for simulation environments..
- Tags unique to AirSim: airsim, autonomous-vehicles, control-systems, cross-platform.
- 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.
Choose hold if…
- hold is primarily Python; AirSim is C++.
- License: hold is MIT, AirSim is Other.
- Tags unique to hold: 3d-reconstruction, augmented-reality, hand-object-interaction, neural-networks.
- When no prior knowledge of object shapes is available but joint 3D reconstruction of hands manipulating objects from single-view videos is needed
When NOT to use hold
- If there are pre-scanned object models that could enhance accuracy beyond self-reconstruction capabilities
- In scenarios where the computational resources for preprocessing and training on custom datasets are insufficient
