nkast.Aether.Physics2D.Collision Namespace Reference

Classes
struct	ContactFeature
	The features that intersect to form the contact point This must be 4 bytes or less. More...
struct	ContactID
	Contact ids to facilitate warm starting. More...
struct	ManifoldPoint
	A manifold point is a contact point belonging to a contact manifold. It holds details related to the geometry and dynamics of the contact points. The local point usage depends on the manifold type: -ShapeType.Circles: the local center of circleB -SeparationFunction.FaceA: the local center of cirlceB or the clip point of polygonB -SeparationFunction.FaceB: the clip point of polygonA This structure is stored across time steps, so we keep it small. Note: the impulses are used for internal caching and may not provide reliable contact forces, especially for high speed collisions. More...
struct	Manifold
	A manifold for two touching convex Shapes. Box2D supports multiple types of contact: More...
struct	ClipVertex
	Used for computing contact manifolds. More...
struct	RayCastInput
	Ray-cast input data. More...
struct	RayCastOutput
	Ray-cast output data. More...
struct	AABB
	An axis aligned bounding box. More...
struct	EPAxis
	This structure is used to keep track of the best separating axis. More...
struct	ReferenceFace
	Reference face used for clipping More...
class	Collision
	Collision methods
struct	DistanceProxy
	A distance proxy is used by the GJK algorithm. It encapsulates any shape. More...
struct	SimplexCache
	Used to warm start ComputeDistance. Set count to zero on first call. More...
struct	DistanceInput
	Input for Distance.ComputeDistance(). You have to option to use the shape radii in the computation. More...
struct	DistanceOutput
	Output for Distance.ComputeDistance(). More...
struct	SimplexVertex
struct	Simplex
class	Distance
	The Gilbert–Johnson–Keerthi distance algorithm that provides the distance between shapes.
struct	TreeNode
	A node in the dynamic tree. The client does not interact with this directly.
class	DynamicTree
	A dynamic tree arranges data in a binary tree to accelerate queries such as volume queries and ray casts. Leafs are proxies with an AABB. In the tree we expand the proxy AABB by Settings.b2_fatAABBFactor so that the proxy AABB is bigger than the client object. This allows the client object to move by small amounts without triggering a tree update. More...
struct	Pair
class	DynamicTreeBroadPhase
	The broad-phase is used for computing pairs and performing volume queries and ray casts. This broad-phase does not persist pairs. Instead, this reports potentially new pairs. It is up to the client to consume the new pairs and to track subsequent overlap. More...
interface	IBroadPhase
class	TOIInput
	Input parameters for CalculateTimeOfImpact More...
struct	TOIOutput
class	SeparationFunction
class	TimeOfImpact

PointState

enum PointState

strong

This is used for determining the state of contact points.

Enumerator
Null	Point does not exist
Add	Point was added in the update
Persist	Point persisted across the update
Remove	Point was removed in the update
