Detailed Description

A mesh shape, consisting of triangles. Mesh shapes are mostly used for static geometry. They can be used by dynamic or kinematic objects but only if they don't collide with other mesh or heightfield shapes as those collisions are currently not supported. Note that if you make a mesh shape a dynamic or kinematic object, you need to provide a mass yourself as mesh shapes don't need to form a closed hull so don't have a well defined volume from which the mass can be calculated.

Constructor & Destructor Documentation

◆ MeshShape() [1/2]

JPH_OVERRIDE_NEW_DELETE MeshShape::MeshShape ( )
inline

Constructor.

◆ MeshShape() [2/2]

MeshShape::MeshShape ( const MeshShapeSettings inSettings,
ShapeResult outResult 
)

Member Function Documentation

◆ CastRay() [1/2]

void MeshShape::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 MeshShape::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.

◆ CollidePoint()

void MeshShape::CollidePoint ( Vec3Arg  inPoint,
const SubShapeIDCreator inSubShapeIDCreator,
CollidePointCollector ioCollector,
const ShapeFilter inShapeFilter = { } 
) const
overridevirtual

See: Shape::CollidePoint Note that for CollidePoint to work for a mesh shape, the mesh needs to be closed (a manifold) or multiple non-intersecting manifolds. Triangles may be facing the interior of the manifold. Insideness is tested by counting the amount of triangles encountered when casting an infinite ray from inPoint. If the number of hits is odd we're inside, if it's even we're outside.

Implements Shape.

◆ CollideSoftBodyVertices()

void MeshShape::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
inCenterOfMassTransformCenter of mass transform for this shape relative to the vertices.
inScaleThe scale to use for this shape
ioVerticesThe vertices of the soft body
inNumVerticesThe number of vertices in ioVertices
inDeltaTimeDelta time of this time step (can be used to extrapolate the position using the velocity of the particle)
inDisplacementDueToGravityDisplacement due to gravity during this time step
inCollidingShapeIndexValue to store in SoftBodyVertex::mCollidingShapeIndex when a collision was found

Implements Shape.

◆ Draw()

void MeshShape::Draw ( DebugRenderer inRenderer,
RMat44Arg  inCenterOfMassTransform,
Vec3Arg  inScale,
ColorArg  inColor,
bool  inUseMaterialColors,
bool  inDrawWireframe 
) const
overridevirtual

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

Implements Shape.

◆ GetInnerRadius()

virtual float MeshShape::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 MeshShape::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 MeshShape::GetMassProperties ( ) const
overridevirtual

Calculate the mass and inertia of this shape.

Implements Shape.

◆ GetMaterial()

const PhysicsMaterial * MeshShape::GetMaterial ( const SubShapeID inSubShapeID) const
overridevirtual

Get the material assigned to a particular sub shape ID.

Implements Shape.

◆ GetMaterialIndex()

uint MeshShape::GetMaterialIndex ( const SubShapeID inSubShapeID) const

Determine which material index a particular sub shape uses (note that if there are no materials this function will return 0 so check the array size) Note: This could for example be used to create a decorator shape around a mesh shape that overrides the GetMaterial call to replace a material with another material.

◆ GetMaterialList()

const PhysicsMaterialList & MeshShape::GetMaterialList ( ) const
inline

Get the list of all materials.

◆ GetStats()

Shape::Stats MeshShape::GetStats ( ) const
overridevirtual

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.

◆ GetSubmergedVolume()

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

◆ GetSubShapeIDBitsRecursive()

uint MeshShape::GetSubShapeIDBitsRecursive ( ) const
overridevirtual

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.

◆ GetSupportingFace()

void MeshShape::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
inSubShapeIDSub shape ID of target shape
inDirectionDirection that the face should be facing (in local space to this shape)
inCenterOfMassTransformTransform to transform outVertices with
inScaleScale of this shape
outVerticesResulting 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 MeshShape::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 MeshShape::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.

◆ GetTrianglesStart()

void MeshShape::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.

◆ GetVolume()

virtual float MeshShape::GetVolume ( ) const
inlineoverridevirtual

Implements Shape.

◆ MustBeStatic()

virtual bool MeshShape::MustBeStatic ( ) const
inlineoverridevirtual

Check if this shape can only be used to create a static body or if it can also be dynamic/kinematic.

Reimplemented from Shape.

overrideprotectedvirtual

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

Reimplemented from Shape.

◆ RestoreMaterialState()

void MeshShape::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.
