Detailed Description

Base class for all convex shapes. Defines a virtual interface.

Member Enumeration Documentation

◆ ESupportMode

enum class ConvexShape::ESupportMode
strong

How the GetSupport function should behave.

Enumerator
ExcludeConvexRadius 

Return the shape excluding the convex radius, Support::GetConvexRadius will return the convex radius if there is one, but adding this radius may not result in the most accurate/efficient representation of shapes with sharp edges.

IncludeConvexRadius 

Return the shape including the convex radius, Support::GetSupport includes the convex radius if there is one, Support::GetConvexRadius will return 0.

Default 

Use both Support::GetSupport add Support::GetConvexRadius to get a support point that matches the original shape as accurately/efficiently as possible.

Member Function Documentation

◆ CastRay() [1/2]

void ConvexShape::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.

Reimplemented in BoxShape, CapsuleShape, ConvexHullShape, CylinderShape, SphereShape, and TriangleShape.

◆ CastRay() [2/2]

bool ConvexShape::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.

Reimplemented in BoxShape, CapsuleShape, CapsuleShape, ConvexHullShape, CylinderShape, CylinderShape, SphereShape, and TriangleShape.

◆ CollidePoint()

void ConvexShape::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.

Reimplemented in BoxShape, CapsuleShape, ConvexHullShape, CylinderShape, SphereShape, and TriangleShape.

◆ DrawGetSupportFunction()

void ConvexShape::DrawGetSupportFunction ( DebugRenderer inRenderer,
RMat44Arg  inCenterOfMassTransform,
Vec3Arg  inScale,
ColorArg  inColor,
bool  inDrawSupportDirection 
) 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.

◆ DrawGetSupportingFace()

void ConvexShape::DrawGetSupportingFace ( DebugRenderer inRenderer,
RMat44Arg  inCenterOfMassTransform,
Vec3Arg  inScale 
) const
overridevirtual

Draw the results of the GetSupportingFace function to show any errors introduced by this process (only relevant for convex shapes)

Reimplemented from Shape.

◆ GetDensity()

float ConvexShape::GetDensity ( ) const
inline

Get density of the shape (kg / m^3)

◆ GetMaterial() [1/2]

const PhysicsMaterial * ConvexShape::GetMaterial ( ) const
inline

◆ GetMaterial() [2/2]

virtual const PhysicsMaterial * ConvexShape::GetMaterial ( const SubShapeID inSubShapeID) const
inlineoverridevirtual

Get the material assigned to a particular sub shape ID.

Implements Shape.

◆ GetSubmergedVolume()

void ConvexShape::GetSubmergedVolume ( Mat44Arg  inCenterOfMassTransform,
Vec3Arg  inScale,
const Plane inSurface,
float &  outTotalVolume,
float &  outSubmergedVolume,
Vec3 &outCenterOfBuoyancy   JPH_IF_DEBUG_RENDERER, RVec3Arg inBaseOffset 
) const
overridevirtual

Reimplemented in ConvexHullShape, SphereShape, and TriangleShape.

◆ GetSubShapeIDBitsRecursive()

virtual uint ConvexShape::GetSubShapeIDBitsRecursive ( ) const
inlineoverridevirtual

Get the max number of sub shape ID bits that are needed to be able to address any leaf shape in this shape. Used mainly for checking that it is smaller or equal than SubShapeID::MaxBits.

Implements Shape.

◆ GetSupportFunction()

virtual const Support * ConvexShape::GetSupportFunction ( ESupportMode  inMode,
SupportBuffer inBuffer,
Vec3Arg  inScale 
) const
pure virtual

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.

Implemented in BoxShape, CapsuleShape, ConvexHullShape, CylinderShape, SphereShape, TaperedCapsuleShape, and TriangleShape.

◆ GetTrianglesNext()

int ConvexShape::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.

Implements Shape.

Reimplemented in BoxShape, CapsuleShape, ConvexHullShape, CylinderShape, SphereShape, and TriangleShape.

◆ GetTrianglesStart()

void ConvexShape::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.

Implements Shape.

Reimplemented in BoxShape, CapsuleShape, ConvexHullShape, CylinderShape, SphereShape, and TriangleShape.

◆ RestoreBinaryState()

void ConvexShape::RestoreBinaryState ( StreamIn inStream)
overrideprotectedvirtual

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

Reimplemented from Shape.

Reimplemented in BoxShape, CapsuleShape, ConvexHullShape, CylinderShape, SphereShape, TaperedCapsuleShape, and TriangleShape.

◆ RestoreMaterialState()

void ConvexShape::RestoreMaterialState ( const PhysicsMaterialRefC inMaterials,
uint  inNumMaterials 
)
overridevirtual

Restore the material references after calling sRestoreFromBinaryState. Note that the exact same materials need to be provided in the same order as returned by SaveMaterialState.

Reimplemented from Shape.

◆ SaveBinaryState()

void ConvexShape::SaveBinaryState ( StreamOut inStream) const
overridevirtual

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

Reimplemented from Shape.

Reimplemented in BoxShape, CapsuleShape, ConvexHullShape, CylinderShape, SphereShape, TaperedCapsuleShape, and TriangleShape.
