I never worked with other physics engines. Godot now I am learning and want to learn how to work with physics in 3D.
Almost all objects in the scene (whether active or static), require the imposition of the physical body. As a minimum the necessary handling collisions.
What are used for this nodes?
What are the possible options that would determine geometric shape of the physical body?
What properties of the physical body is available in Godot?
As I understand it: for geometrically complex objects, the shape of the physical body sets in the form of a grid mesh. So use 2 grids: one (more detailed) for visualization of the object and the second (simplified) to handle physics.
How to do this in Godot?
