Struct oxygengine_physics_2d::prelude::Compound

pub struct Compound<N> where
    N: RealField,  { /* fields omitted */ }

A compound shape with an aabb bounding volume.

A compound shape is a shape composed of the union of several simpler shape. This is the main way of creating a concave shape from convex parts. Each parts can have its own delta transformation to shift or rotate it with regard to the other shapes.
