Methods

ContainsPoint(Vector3d, FixedQuaternion, ReadOnlySpan<Vector3d>, ReadOnlySpan<int>, Vector3d, FixedPointAnchor)

Tests whether a point lies in or on a closed convex hull. The supplied interior point determines the accepted side of consistently wound faces.

public static bool ContainsPoint(Vector3d hullOrigin, FixedQuaternion hullRotation, ReadOnlySpan<Vector3d> hullLocalPoints, ReadOnlySpan<int> triangleVertexIndices, Vector3d hullInteriorLocalPoint, FixedPointAnchor point)

Parameters

hullOrigin Vector3d

hullRotation FixedQuaternion

hullLocalPoints ReadOnlySpan<Vector3d>

triangleVertexIndices ReadOnlySpan<int>

hullInteriorLocalPoint Vector3d

point FixedPointAnchor

Returns

bool

TryGetCenteredCapsuleContact(Vector3d, FixedQuaternion, ReadOnlySpan<Vector3d>, ReadOnlySpan<int>, ReadOnlySpan<int>, Vector3d, FixedQuaternion, Vector3d, Fixed64, Fixed64, out FixedContactAnchors)

Attempts to obtain the minimum-translation contact between a rigidly transformed convex hull and a centered capsule.

public static bool TryGetCenteredCapsuleContact(Vector3d hullOrigin, FixedQuaternion hullRotation, ReadOnlySpan<Vector3d> hullLocalPoints, ReadOnlySpan<int> triangleVertexIndices, ReadOnlySpan<int> edgeVertexPairs, Vector3d capsuleCenter, FixedQuaternion capsuleRotation, Vector3d capsuleLocalAxisDirection, Fixed64 capsuleAxisLength, Fixed64 capsuleRadius, out FixedContactAnchors contact)

Parameters

hullOrigin Vector3d

hullRotation FixedQuaternion

hullLocalPoints ReadOnlySpan<Vector3d>

triangleVertexIndices ReadOnlySpan<int>

edgeVertexPairs ReadOnlySpan<int>

capsuleCenter Vector3d

capsuleRotation FixedQuaternion

capsuleLocalAxisDirection Vector3d

capsuleAxisLength Fixed64

capsuleRadius Fixed64

contact FixedContactAnchors

Returns

bool

Remarks

The returned normal points from the hull toward the capsule. Hull points remain in their canonical local frame throughout the exact SAT.

TryGetContact(Vector3d, FixedQuaternion, ReadOnlySpan<Vector3d>, ReadOnlySpan<int>, ReadOnlySpan<int>, Vector3d, FixedQuaternion, ReadOnlySpan<Vector3d>, ReadOnlySpan<int>, ReadOnlySpan<int>, out FixedContactAnchors)

Attempts to obtain the minimum-translation contact between two rigidly transformed convex hulls.
