Constructor & Destructor Documentation

◆ RotatedTranslatedShape() [1/3]

JPH_OVERRIDE_NEW_DELETE RotatedTranslatedShape::RotatedTranslatedShape ( )

inline

Constructor.

◆ RotatedTranslatedShape() [2/3]

RotatedTranslatedShape::RotatedTranslatedShape	(	const RotatedTranslatedShapeSettings &	inSettings,
		ShapeResult &	outResult
	)

◆ RotatedTranslatedShape() [3/3]

RotatedTranslatedShape::RotatedTranslatedShape	(	Vec3Arg	inPosition,
		QuatArg	inRotation,
		const Shape *	inShape
	)

Member Function Documentation

◆ CastRay() [1/2]

void RotatedTranslatedShape::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)).

Implements Shape.

◆ CastRay() [2/2]

bool RotatedTranslatedShape::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)).

Implements Shape.

◆ CollectTransformedShapes()

void RotatedTranslatedShape::CollectTransformedShapes	(	const AABox &	inBox,
		Vec3Arg	inPositionCOM,
		QuatArg	inRotation,
		Vec3Arg	inScale,
		const SubShapeIDCreator &	inSubShapeIDCreator,
		TransformedShapeCollector &	ioCollector,
		const ShapeFilter &	inShapeFilter
	)		const

overridevirtual

Collect the leaf transformed shapes of all leaf shapes of this shape. inBox is the world space axis aligned box which leaf shapes should collide with. inPositionCOM/inRotation/inScale describes the transform of this shape. inSubShapeIDCeator represents the current sub shape ID of this shape.

Reimplemented from Shape.

◆ CollidePoint()

void RotatedTranslatedShape::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.

Implements Shape.

◆ CollideSoftBodyVertices()

void RotatedTranslatedShape::CollideSoftBodyVertices	(	Mat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale,
		const CollideSoftBodyVertexIterator &	inVertices,
		uint	inNumVertices,
		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.

	)		const

overridevirtual

Draw the results of the GetSupportFunction with the convex radius added back on to show any errors introduced by this process (only relevant for convex shapes)

Reimplemented from Shape.

		RMat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale
	)		const

Reimplemented from Shape.

◆ GetCenterOfMass()

virtual Vec3 RotatedTranslatedShape::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 DecoratedShape.

◆ GetInnerRadius()

virtual float RotatedTranslatedShape::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()

AABox RotatedTranslatedShape::GetLocalBounds ( ) const

overridevirtual

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

Implements Shape.

◆ GetMassProperties()

MassProperties RotatedTranslatedShape::GetMassProperties ( ) const

overridevirtual

Calculate the mass and inertia of this shape.

Implements Shape.

◆ GetPosition()

Vec3 RotatedTranslatedShape::GetPosition ( ) const

inline

Access the translation that has been applied to the inner shape.

◆ GetRotation()

Quat RotatedTranslatedShape::GetRotation ( ) const

inline

Access the rotation that is applied to the inner shape.

◆ GetStats()

virtual Stats RotatedTranslatedShape::GetStats ( ) const

inlineoverridevirtual

Get stats of this shape. Use for logging / data collection purposes only. Does not add values from child shapes, use GetStatsRecursive for this.

Implements Shape.

		Vec3Arg	inScale,
		const Plane &	inSurface,
		float &	outTotalVolume,
		float &	outSubmergedVolume,
		Vec3 &outCenterOfBuoyancy	JPH_IF_DEBUG_RENDERER, RVec3Arg inBaseOffset
	)		const

overridevirtual

◆ GetSubShapeTransformedShape()

TransformedShape RotatedTranslatedShape::GetSubShapeTransformedShape	(	const SubShapeID &	inSubShapeID,
		Vec3Arg	inPositionCOM,
		QuatArg	inRotation,
		Vec3Arg	inScale,
		SubShapeID &	outRemainder
	)		const

overridevirtual

Get the direct child sub shape and its transform for a sub shape ID.

Parameters

inSubShapeID	Sub shape ID that indicates the path to the leaf shape
inPositionCOM	The position of the center of mass of this shape
inRotation	The orientation of this shape
inScale	Scale in local space of the shape (scales relative to its center of mass)
outRemainder	The remainder of the sub shape ID after removing the sub shape

Returns: Direct child sub shape and its transform, note that the body ID and sub shape ID will be invalid

Reimplemented from Shape.

◆ GetSupportingFace()

void RotatedTranslatedShape::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 in local space of the shape (scales relative to its center of mass)
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 DecoratedShape.

◆ GetSurfaceNormal()

Vec3 RotatedTranslatedShape::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()

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

inlineoverridevirtual

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.

Implements Shape.

◆ GetTrianglesStart()

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

inlineoverridevirtual

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.

Implements Shape.

◆ GetVolume()

virtual float RotatedTranslatedShape::GetVolume ( ) const

inlineoverridevirtual

Implements Shape.

◆ GetWorldSpaceBounds() [1/3]

AABox Shape::GetWorldSpaceBounds	(	DMat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale
	)		const

inline

Get world space bounds including convex radius.

◆ GetWorldSpaceBounds() [2/3]

virtual AABox Shape::GetWorldSpaceBounds	(	Mat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale
	)		const

inlinevirtual

Get world space bounds including convex radius. This shape is scaled by inScale in local space first. This function can be overridden to return a closer fitting world space bounding box, by default it will just transform what GetLocalBounds() returns.

Reimplemented from Shape.

◆ GetWorldSpaceBounds() [3/3]

AABox RotatedTranslatedShape::GetWorldSpaceBounds	(	Mat44Arg	inCenterOfMassTransform,
		Vec3Arg	inScale
	)		const

overridevirtual

Get world space bounds including convex radius. This shape is scaled by inScale in local space first. This function can be overridden to return a closer fitting world space bounding box, by default it will just transform what GetLocalBounds() returns.

Reimplemented from Shape.

◆ IsValidScale()

bool RotatedTranslatedShape::IsValidScale ( Vec3Arg inScale ) const

overridevirtual

Test if inScale is a valid scale for this shape. Some shapes can only be scaled uniformly, compound shapes cannot handle shapes being rotated and scaled (this would cause shearing), scale can never be zero. When the scale is invalid, the function will return false.

Here's a list of supported scales:

SphereShape: Scale must be uniform (signs of scale are ignored).
BoxShape: Any scale supported (signs of scale are ignored).
TriangleShape: Any scale supported when convex radius is zero, otherwise only uniform scale supported.
CapsuleShape: Scale must be uniform (signs of scale are ignored).
TaperedCapsuleShape: Scale must be uniform (sign of Y scale can be used to flip the capsule).
CylinderShape: Scale must be uniform in XZ plane, Y can scale independently (signs of scale are ignored).
RotatedTranslatedShape: Scale must not cause shear in the child shape.
CompoundShape: Scale must not cause shear in any of the child shapes.

Reimplemented from DecoratedShape.

◆ MakeScaleValid()

Vec3 RotatedTranslatedShape::MakeScaleValid ( Vec3Arg inScale ) const

overridevirtual

This function will make sure that if you wrap this shape in a ScaledShape that the scale is valid. Note that this involves discarding components of the scale that are invalid, so the resulting scaled shape may be different than the requested scale. Compare the return value of this function with the scale you passed in to detect major inconsistencies and possibly warn the user.

Parameters

inScale Local space scale for this shape.

Returns: Scale that can be used to wrap this shape in a ScaledShape. IsValidScale will return true for this scale.

Reimplemented from DecoratedShape.

◆ RestoreBinaryState()

◆ TransformShape()

void RotatedTranslatedShape::TransformShape	(	Mat44Arg	inCenterOfMassTransform,
		TransformedShapeCollector &	ioCollector
	)		const

overridevirtual

Transforms this shape and all of its children with inTransform, resulting shape(s) are passed to ioCollector. Note that not all shapes support all transforms (especially true for scaling), the resulting shape will try to match the transform as accurately as possible.

Parameters

inCenterOfMassTransform	The transform (rotation, translation, scale) that the center of mass of the shape should get
ioCollector	The transformed shapes will be passed to this collector
