This inheritance list is sorted roughly, but not completely, alphabetically:

[detail level 12]

Cstw::BroadPhaseGrid	A grid in which the physical object are placed in. This is used to optimize performance by only checking collision with colliders that are in the same cell
▼Cstw::Collider	A pure virtual struct that represents colliders
Cstw::AabbCollider	An Axis Aligned Bounding Box collider
Cstw::BoxCollider	A rotatable box collider
Cstw::CircleCollider	A circle collider
Cstw::Collision	Struct representing a collision
▼Cstw::CollisionBody	A body that can receive collisions
Cstw::Rigidbody	A Rigidbody that has dynamics
▼Cstw::CollisionWorld	Represents a world where collisions can happen. It does not have dynamics, for this you will need the DynamicsWorld
Cstw::DynamicsWorld	A world with dynamics in it
Cstw::Edge
Cstw::Manifold
Cstw::Projection
Cstw::Simplex	Struct representing the simplest form that can "select" an area in any dimension
▼Cstw::Solver	Generic class for all solvers
Cstw::ImpulseSolver	Solver with impulse and friction
Cstw::SmoothPositionSolver	A solver to smooth out collision with collider that are in a tower placement
Cstw::Transform	A transform of an object. Contains position, scale and rotation
Cstw::Vector2	A struct representing a 2D Vector
