Detailed Description

a 3D cell defined by a set of convex points

vtkConvexPointSet is a concrete implementation that represents a 3D cell defined by a convex set of points. An example of such a cell is an octant (from an octree). vtkConvexPointSet uses the ordered triangulations approach (vtkOrderedTriangulator) to create triangulations guaranteed to be compatible across shared faces. This allows a general approach to processing complex, convex cell types.

Reimplemented from vtkCell3D.

◆ EvaluatePosition()

int vtkConvexPointSet::EvaluatePosition ( const double  x[3],
double  closestPoint[3],
int &  subId,
double  pcoords[3],
double &  dist2,
double  weights[] 
)
overridevirtual

Satisfy the vtkCell API.

This method determines the subId, pcoords, and weights by triangulating the convex point set, and then determining which tetrahedron the point lies in.

Implements vtkCell.

◆ EvaluateLocation()

void vtkConvexPointSet::EvaluateLocation ( int &  subId,
const double  pcoords[3],
double  x[3],
double *  weights 
)
overridevirtual

The inverse of EvaluatePosition.

Implements vtkCell.

◆ IntersectWithLine()

int vtkConvexPointSet::IntersectWithLine ( const double  p1[3],
const double  p2[3],
double  tol,
double &  t,
double  x[3],
double  pcoords[3],
int &  subId 
)
overridevirtual

Triangulates the cells and then intersects them to determine the intersection point.

Implements vtkCell.

◆ TriangulateLocalIds()

int vtkConvexPointSet::TriangulateLocalIds ( int  index,
vtkIdList ptIds 
)
overridevirtual

Triangulate using methods of vtkOrderedTriangulator.

Implements vtkCell.

◆ Derivatives()

void vtkConvexPointSet::Derivatives ( int  subId,
const double  pcoords[3],
const double *  values,
int  dim,
double *  derivs 
)
overridevirtual

Computes derivatives by triangulating and from subId and pcoords, evaluating derivatives on the resulting tetrahedron.

Implements vtkCell.

◆ CellBoundary()

int vtkConvexPointSet::CellBoundary ( int  subId,
const double  pcoords[3],
vtkIdList pts 
)
overridevirtual

Returns the set of points forming a face of the triangulation of these points that are on the boundary of the cell that are closest parametrically to the point specified.

Implements vtkCell.

◆ GetParametricCenter()

int vtkConvexPointSet::GetParametricCenter ( double  pcoords[3])
inlineoverridevirtual

Return the center of the cell in parametric coordinates.

Reimplemented from vtkCell.

◆ IsPrimaryCell()

int vtkConvexPointSet::IsPrimaryCell ( )
inlineoverridevirtual

A convex point set is triangulated prior to any operations on it so it is not a primary cell, it is a composite cell.

Reimplemented from vtkCell.

Definition at line 215 of file vtkConvexPointSet.h.

◆ InterpolateFunctions()

void vtkConvexPointSet::InterpolateFunctions ( const double  pcoords[3],
double *  sf 
)
override

Compute the interpolation functions/derivatives (aka shape functions/derivatives)

◆ InterpolateDerivs()

void vtkConvexPointSet::InterpolateDerivs ( const double  pcoords[3],
double *  derivs 
)
override

Compute the interpolation functions/derivatives (aka shape functions/derivatives)
