Struct ncollide2d::shape::Compound

pub struct Compound<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.
