Detailed Description

A convex hull.

Constructor & Destructor Documentation

◆ ConvexHullShape() [1/2]

ConvexHullShape::ConvexHullShape ( )

inline

Constructor.

◆ ConvexHullShape() [2/2]

ConvexHullShape::ConvexHullShape	(	const ConvexHullShapeSettings &	inSettings,
		ShapeResult &	outResult
	)

Member Function Documentation

◆ CastRay() [1/2]

void ConvexHullShape::CastRay	(	const RayCast &	inRay,
		const RayCastSettings &	inRayCastSettings,
		const SubShapeIDCreator &	inSubShapeIDCreator,
		CastRayCollector &	ioCollector,
		const ShapeFilter &	inShapeFilter = `{ }`
	)		const

overridevirtual

Cast a ray against this shape. Allows returning multiple hits through ioCollector. Note that this version is more flexible but also slightly slower than the CastRay function that returns only a single hit. If you want the surface normal of the hit use GetSurfaceNormal(collected sub shape ID, inRay.GetPointOnRay(collected faction)).

Reimplemented from ConvexShape.

◆ CastRay() [2/2]

bool ConvexHullShape::CastRay	(	const RayCast &	inRay,
		const SubShapeIDCreator &	inSubShapeIDCreator,
		RayCastResult &	ioHit
	)		const

overridevirtual

Cast a ray against this shape, returns true if it finds a hit closer than ioHit.mFraction and updates that fraction. Otherwise ioHit is left untouched and the function returns false. Note that the ray should be relative to the center of mass of this shape (i.e. subtract Shape::GetCenterOfMass() from RayCast::mOrigin if you want to cast against the shape in the space it was created). Convex objects will be treated as solid (meaning if the ray starts inside, you'll get a hit fraction of 0) and back face hits against triangles are returned. If you want the surface normal of the hit use GetSurfaceNormal(ioHit.mSubShapeID2, inRay.GetPointOnRay(ioHit.mFraction)).

Reimplemented from ConvexShape.

◆ CollidePoint()

void ConvexHullShape::CollidePoint	(	Vec3Arg	inPoint,
		const SubShapeIDCreator &	inSubShapeIDCreator,
		CollidePointCollector &	ioCollector,
		const ShapeFilter &	inShapeFilter = `{ }`
	)		const

overridevirtual

Check if inPoint is inside this shape. For this tests all shapes are treated as if they were solid. Note that inPoint should be relative to the center of mass of this shape (i.e. subtract Shape::GetCenterOfMass() from inPoint if you want to test against the shape in the space it was created). For a mesh shape, this test will only provide sensible information if the mesh is a closed manifold. For each shape that collides, ioCollector will receive a hit.

Reimplemented from ConvexShape.

◆ CollideSoftBodyVertices()

void ConvexHullShape::CollideSoftBodyVertices	(	Mat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale,
		SoftBodyVertex *	ioVertices,
		uint	inNumVertices,
		float	inDeltaTime,
		Vec3Arg	inDisplacementDueToGravity,
		int	inCollidingShapeIndex
	)		const

overridevirtual

Collides all vertices of a soft body with this shape and updates SoftBodyVertex::mCollisionPlane, SoftBodyVertex::mCollidingShapeIndex and SoftBodyVertex::mLargestPenetration if a collision with more penetration was found.

Parameters

inCenterOfMassTransform	Center of mass transform for this shape relative to the vertices.
inScale	The scale to use for this shape
ioVertices	The vertices of the soft body
inNumVertices	The number of vertices in ioVertices

inDisplacementDueToGravity	Displacement due to gravity during this time step
inCollidingShapeIndex	Value to store in SoftBodyVertex::mCollidingShapeIndex when a collision was found

Implements Shape.

	)		const

overridevirtual

Draw the shape at a particular location with a particular color (debugging purposes)

Implements Shape.

void ConvexHullShape::DrawShrunkShape	(	DebugRenderer *	inRenderer,
		RMat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale
	)		const

◆ GetCenterOfMass()

virtual Vec3 ConvexHullShape::GetCenterOfMass ( ) const

inlineoverridevirtual

All shapes are centered around their center of mass. This function returns the center of mass position that needs to be applied to transform the shape to where it was created.

Reimplemented from Shape.

◆ GetConvexRadius()

float ConvexHullShape::GetConvexRadius ( ) const

inline

Get the convex radius of this convex hull.

◆ GetFaceVertices()

uint ConvexHullShape::GetFaceVertices	(	uint	inFaceIndex,
		uint	inMaxVertices,
		uint *	outVertices
	)		const

inline

Get the vertices indices of a face

Parameters

inFaceIndex	Index of the face.
inMaxVertices	Maximum number of vertices to return.
outVertices	Array of vertices indices, must be at least inMaxVertices in size, the vertices are returned in counter clockwise order and the positions can be obtained using GetPoint(index).

Returns: Number of vertices in face, if this is bigger than inMaxVertices, not all vertices were retrieved.

◆ GetInnerRadius()

virtual float ConvexHullShape::GetInnerRadius ( ) const

inlineoverridevirtual

Returns the radius of the biggest sphere that fits entirely in the shape. In case this shape consists of multiple sub shapes, it returns the smallest sphere of the parts. This can be used as a measure of how far the shape can be moved without risking going through geometry.

Implements Shape.

◆ GetLocalBounds()

virtual AABox ConvexHullShape::GetLocalBounds ( ) const

inlineoverridevirtual

Get local bounding box including convex radius, this box is centered around the center of mass rather than the world transform.

Implements Shape.

overridevirtual

Calculate the mass and inertia of this shape.

Implements Shape.

Implements Shape.

◆ GetSubmergedVolume()

void ConvexHullShape::GetSubmergedVolume	(	Mat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale,
		const Plane &	inSurface,
		float &	outTotalVolume,

	)		const

overridevirtual

Reimplemented from ConvexShape.

◆ GetSupportFunction()

const ConvexShape::Support * ConvexHullShape::GetSupportFunction	(	ESupportMode	inMode,
		SupportBuffer &	inBuffer,
		Vec3Arg	inScale
	)		const

overridevirtual

Returns an object that provides the GetSupport function for this shape. inMode determines if this support function includes or excludes the convex radius. of the values returned by the GetSupport function. This improves numerical accuracy of the results. inScale scales this shape in local space.

Implements ConvexShape.

◆ GetSupportingFace()

void ConvexHullShape::GetSupportingFace	(	const SubShapeID &	inSubShapeID,
		Vec3Arg	inDirection,
		Vec3Arg	inScale,
		Mat44Arg	inCenterOfMassTransform,
		SupportingFace &	outVertices
	)		const

overridevirtual

Get the vertices of the face that faces inDirection the most (includes any convex radius). Note that this function can only return faces of convex shapes or triangles, which is why a sub shape ID to get to that leaf must be provided.

Parameters

inSubShapeID	Sub shape ID of target shape
inDirection	Direction that the face should be facing (in local space to this shape)
inCenterOfMassTransform	Transform to transform outVertices with
inScale	Scale of this shape
outVertices	Resulting face. The returned face can be empty if the shape doesn't have polygons to return (e.g. because it's a sphere). The face will be returned in world space.

Reimplemented from Shape.

◆ GetSurfaceNormal()

Vec3 ConvexHullShape::GetSurfaceNormal	(	const SubShapeID &	inSubShapeID,
		Vec3Arg	inLocalSurfacePosition
	)		const

overridevirtual

Get the surface normal of a particular sub shape ID and point on surface (all vectors are relative to center of mass for this shape). Note: When you have a CollideShapeResult or ShapeCastResult you should use -mPenetrationAxis.Normalized() as contact normal as GetSurfaceNormal will only return face normals (and not vertex or edge normals).

Implements Shape.

◆ GetTrianglesNext()

int ConvexHullShape::GetTrianglesNext	(	GetTrianglesContext &	ioContext,
		int	inMaxTrianglesRequested,
		Float3 *	outTriangleVertices,
		const PhysicsMaterial **	outMaterials = `nullptr`
	)		const

overridevirtual

Call this repeatedly to get all triangles in the box. outTriangleVertices should be large enough to hold 3 * inMaxTriangleRequested entries. outMaterials (if it is not null) should contain inMaxTrianglesRequested entries. The function returns the amount of triangles that it found (which will be <= inMaxTrianglesRequested), or 0 if there are no more triangles. Note that the function can return a value < inMaxTrianglesRequested and still have more triangles to process (triangles can be returned in blocks). Note that the function may return triangles outside of the requested box, only coarse culling is performed on the returned triangles.

Reimplemented from ConvexShape.

◆ GetTrianglesStart()

void ConvexHullShape::GetTrianglesStart	(	GetTrianglesContext &	ioContext,
		const AABox &	inBox,
		Vec3Arg	inPositionCOM,
		QuatArg	inRotation,
		Vec3Arg	inScale
	)		const

overridevirtual

To start iterating over triangles, call this function first. ioContext is a temporary buffer and should remain untouched until the last call to GetTrianglesNext. inBox is the world space bounding in which you want to get the triangles. inPositionCOM/inRotation/inScale describes the transform of this shape. To get the actual triangles call GetTrianglesNext.

Reimplemented from ConvexShape.

◆ GetVolume()

virtual float ConvexHullShape::GetVolume ( ) const

inlineoverridevirtual

Implements Shape.

◆ RestoreBinaryState()

void ConvexHullShape::RestoreBinaryState ( StreamIn & inStream )

overrideprotectedvirtual

This function should not be called directly, it is used by sRestoreFromBinaryState.

Reimplemented from ConvexShape.

◆ SaveBinaryState()

void ConvexHullShape::SaveBinaryState ( StreamOut & inStream ) const

overridevirtual

Saves the contents of the shape in binary form to inStream.

Reimplemented from ConvexShape.

void ConvexHullShape::sRegister ( )

static

Member Data Documentation

◆ cMaxPointsInHull

JPH_OVERRIDE_NEW_DELETE constexpr int ConvexHullShape::cMaxPointsInHull = 256

staticconstexpr

Maximum amount of points supported in a convex hull. Note that while constructing a hull, interior points are discarded so you can provide more points. The ConvexHullShapeSettings::Create function will return an error when too many points are provided.

inlinestatic

Draw the outlines of the faces of the convex hull when drawing the shape.
