Enum Broadphase 

#[non_exhaustive]
pub enum Broadphase {
    Bvh,
    DynamicTree,
    Hybrid,
}

The broad-phase PhysicsWorld uses to find the pairs of bodies whose colliders may touch.

A body’s box is the closed-form world box of its collider when it carries a shape or a compound, and the cube of its collision sphere otherwise. Every kind hands its candidates (pairs whose boxes may overlap) to the same exact narrow-phase in ascending pair order, and a pair whose boxes do not meet has no contact, so a world steps to bit-identical results whichever it uses; they differ in cost. Set with PhysicsWorld::set_broadphase.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bvh

A linear BVH over Morton codes, rebuilt from scratch every step. Default.

DynamicTree

A persistent dynamic AABB tree (crate::dynamic_bvh::DynamicAabbTree): each body keeps a fattened proxy that is only re-inserted when the body leaves it, so a world where most bodies move little pays for the few that do.

Hybrid

Static bodies in a BVH rebuilt only when the static set changes, small dynamic bodies in a sparse hash grid whose cell size follows the median body, and large dynamic bodies in a per-step BVH; reports exactly the pairs whose boxes overlap. Fastest when many bodies are static or bodies are of similar size. The sleep skip (PhysicsWorld::set_sleep_skip) parks bodies only with Broadphase::Bvh; with this kind every body is staged every step.
