physics simulation

The session "Discover RealityKit APIs for iOS, macOS and visionOS" covers various aspects of physics simulation, particularly focusing on force effects and physics joints. Here are some key points:

1. Force Effects:

   • The session explains how to use the Force Effects API to simulate real-world physics, such as making asteroids orbit around a planet. This involves creating custom force effects that apply forces to physics bodies within a defined volume.
   • Different types of built-in force effects are discussed, including constant radial effects, vortex effects, drag effects, and turbulence effects. For example, a custom gravity effect can be created to pull asteroids towards a planet's center, simulating orbital motion by setting initial velocities.

2. Physics Joints:

   • The session also covers the use of physics joints to connect two physics bodies with constraints, making the connection feel more realistic. For instance, a joint can be created to connect a spaceship and a trailer, allowing for rotations but limiting translations to simulate how real-world trailers work.

For more detailed information, you can refer to the chapter on "Force effects and joints" in the session Discover RealityKit APIs for iOS, macOS and visionOS.
