Working on Landing GearAt the moment I am developing the landing gear for the spacecraft in the upcoming sfsim simulator.

The Jolt Physics library provides a great physics implementation for wheeled vehicles.
Previously I have implemented extracting a small part from the planet mesh and convert it to a Jolt Physics mesh.
This then can be used to simulate the behaviour of the suspension and the wheels when the gear makes contact with the ground.

I am also working on an animation for gear deployment.
Blender supports different constraints such as inverse kinematics as shown in Mark Alloway's tutorial.
Here is a video showing the first working version of the landing gear (doors not implemented yet).

Only part left to do is baking animations, exporting it to glTF and driving the animations using information from Jolt Physics.
Let me know if you have any comments or suggestions.
If you are interested in a realistic space flight simulator, please consider wishlisting sfsim on Steam.
[ 2025-05-07 22:20:51 CET ] [ Original post ] sfsim is a space flight simulator with realistic physics and a true-to-scale Earth using NASA Bluemarble data.
Current key features
- Realistic Physics: Simulate space flight and aerodynamics.
- True-to-scale Earth: Earth model based on NASA Bluemarble data.
- Realistic atmosphere: Atmosphere with realistic temperature and density as well as procedurally generated volumetric clouds.
- Real celestial body positions: Position of Earth and Sun based on NASA data.
