Physics Simulate Rigid Body
Performs a rigid body simulation. The simulation spawns rigid bodies (primitives or meshes) on the points of the point cloud. A world can be included that simulates the ground such as a flat plane or a height-field based on an input height map.
The simulation then applies gravity and other world forces to simulate the behavior of bodies colliding with each other and the world. The duration of the simulation depends on the Iterations where the TimeStep denotes the physical time passed in milliseconds between each simulation iteration. If the TimeStep is too high, the simulation might miss collisions for high velocity objects.
Therefore, the total simulation time in milliseconds is TimeStep * Iterations. By default, the node simulates one second using a 20fps simulation, resulting in 20 Iterations and a TimeStep of 50ms.

A world can be included that simulates the ground such as a flat plane or a height-field based on an input height map. The simulation then applies gravity and other world forces to simulate the behavior of bodies colliding with each other and the world. The duration of the simulation depends on the `Iterations` where the `TimeStep` denotes the physical time passed in milliseconds between each simulation iteration. If the `TimeStep` is too high, the simulation might miss collisions for high velocity objects. Therefore, the total simulation time in milliseconds is `TimeStep` * `Iterations`. By default, the node simulates one second using a 20fps simulation, resulting in 20 `Iterations` and a `TimeStep` of 50ms. | Name | Physics Simulate Rigid Body | Version | 1.98 | ID | fe3e40e2-ec3c-43cd-9a5c-0663008a853f | PackageUrl | pkg://91e4a3d7-8a94-4d6b-8604-6fec07f6a28b/atoms/fe3e40e2-ec3c-43cd-9a5c-0663008a853f.atom |
