virtual void GEO_VolumeElementBase::addPointRefToGroup ( GA_PointGroup & grp ) const

virtual

void GEO_VolumeElementBase::addToBSphere ( UT_BoundingSphere * bsphere ) const

overridevirtual

Enlarge the bounding sphere with the primitive's bounds. By default, this will enlarge the bounding sphere by the primitive's bounding box (i.e. getBBox()). It may be possible to have a tighter bound (i.e. the vertex hull for many primitives is a much better metric).

Reimplemented from GEO_Primitive.

UT_Vector3 GEO_VolumeElementBase::baryCenter ( ) const

overridevirtual

Return the center of the primitive. This defaults to the center of the bounding box. A better approximation might be the average value of the vertex positions (which could be different).

Reimplemented from GEO_Primitive.

UT_Vector3D GEO_VolumeElementBase::baryCenterD ( ) const

overridevirtual

Reimplemented from GEO_Primitive.

static GA_Offset GEO_VolumeElementBase::buildBlock	(	GA_Detail *	detail,
		const GA_Offset	startpt,
		const GA_Size	npoints,
		const GA_Size	nprims,
		GA_PrimitiveTypeId	primtype,
		int	vertexperprim,
		const int *	primpointnumbers
	)

static

Builds volumeelements using the specified range of point offsets, as dictated by nprims and primpointnumbers, in parallel. primpointnumbers lists the offsets of the points used by each volumeelemnt MINUS startpt, i.e. they are offsets relative to startpt, not indices relative to startpt. The offset of the first hexahedron is returned, and the rest are at consecutive offsets. All hexpointnumbers must be between 0 (inclusive) and npoints (exclusive).

NOTE: Existing primitives are allowed to be using the points in the specified range already, and the elements being created do not do not need to use all of the points in the range. However, these cases may impact performance.

UT_Vector3 GEO_VolumeElementBase::computeNormal ( ) const

bool GEO_VolumeElementBase::evaluateBaryCenterRefMap	(	GA_Offset	result_vtx,

By default, this will call evaluateInteriorPointRefMap with u=.5 and v=.5. This is likely not the perfect solution. At the current time, this is only used in POPs to birth points at primitive centers.

inlineoverrideprotectedvirtual

Evaluate the position for the given parametric coordinates (with the given derivatives). Return 0 if successful, or -1 if failure. The default implementation returns {0,0,0,0};

Reimplemented from GEO_Primitive.

Definition at line 141 of file GEO_VolumeElementBase.h.

virtual GA_Offset GEO_VolumeElementBase::findSharedFace ( GA_Size faceno ) const

pure virtual

Returns any primitive sharing the face of the same type, so tet only returns tet and hex only returns hex. See volumelement for a more general version.

Implemented in GEO_PrimHexahedron, and GEO_PrimTetrahedron.

bool GEO_VolumeElementBase::getBBox ( UT_BoundingBox * bbox ) const

overridevirtual

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation). This function should always initialize bbox, even if returning false, in which case, the bbox->isValid() may be false, representing an empty bounding box. This function should also not use any initial value of bbox, so it does not need to be initialized beforehand.

Implements GEO_Primitive.

virtual GA_Size GEO_VolumeElementBase::getEdgeCount ( ) const

pure virtual

The number of edges in this volume.

Implemented in GEO_PrimHexahedron, and GEO_PrimTetrahedron.

virtual void GEO_VolumeElementBase::getEdgeIndices	(	GA_Size	edgeno,
		int &	e0,
		int &	e1
	)		const

pure virtual

Returns the indices of the edge. Note each edge shows up once and due to the nature of volumes, is undirected.

Implemented in GEO_PrimHexahedron, and GEO_PrimTetrahedron.

virtual GA_Size GEO_VolumeElementBase::getFaceCount ( ) const

pure virtual

The number of faces that make up this volume.

Implemented in GEO_PrimHexahedron, and GEO_PrimTetrahedron.

virtual int GEO_VolumeElementBase::getFaceIndexCount ( GA_Size faceno ) const

pure virtual

Returns the number of indices in specified face.

Implemented in GEO_PrimHexahedron, and GEO_PrimTetrahedron.

virtual int GEO_VolumeElementBase::getFaceIndices	(	GA_Size	faceno,
		UT_Array< int > &	vtxlist

pure virtual

Returns the indices to the vertices, not the vertex offsets!

Implemented in GEO_PrimHexahedron, and GEO_PrimTetrahedron.

Method to determine if a primitive has an edge (undirected).

Reimplemented from GEO_Primitive.

Definition at line 50 of file GEO_VolumeElementBase.h.

void GEO_VolumeElementBase::iterateEdges ( GA_IterateEdgesFunc apply_func ) const

Calls apply_func for each directed edge on the primitive. If the apply_func function returns false, then the traversal will be stopped.

Reimplemented from GA_Primitive.

Definition at line 65 of file GEO_VolumeElementBase.h.

void GEO_VolumeElementBase::iterateEdgesByVertex ( GA_IterateEdgesByVertexFunc apply_func ) const

inlineoverridevirtual

Calls apply_func for each directed edge on the primitive, passing in the GA_Size primitive vertex index for each point on the edge. If the apply_func function returns false, then the traversal will be stopped.

Reimplemented from GA_Primitive.

Definition at line 79 of file GEO_VolumeElementBase.h.

static GA_IntrinsicManager::Registrar GEO_VolumeElementBase::registerIntrinsics ( GA_PrimitiveDefinition & defn )

inlinestaticprotected

All subclasses should call this method to register the intrinsics.

virtual bool GEO_VolumeElementBase::vertexApply	(	bool()(GA_Offset vtx, void )	apply,

virtual

Apply the function to each vertex of the primitive. Break when the function returns true. Return the value of the last function applied (false if never called).
