Member Function Documentation

vtkVertex* vtkVertex::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkObject.

virtual const char* vtkVertex::GetClassName ( ) [virtual]

Reimplemented from vtkCell.

int vtkVertex::IsTypeOf ( const char * type ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkCell.

virtual int vtkVertex::IsA ( const char * type ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkCell.

vtkVertex* vtkVertex::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkCell.

int vtkVertex::GetCellType ( ) [inline, virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.

int vtkVertex::GetCellDimension ( ) [inline, virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.
Definition at line 60 of file vtkVertex.h.

int vtkVertex::GetNumberOfEdges ( ) [inline, virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.

int vtkVertex::GetNumberOfFaces ( ) [inline, virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.

vtkCell* vtkVertex::GetEdge ( int ) [inline, virtual]

See the vtkCell API for descriptions of these methods.

vtkCell* vtkVertex::GetFace ( int ) [inline, virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.

void vtkVertex::Clip ( float value,

vtkDataArray * cellScalars,

vtkPointLocator * locator,

vtkCellArray * pts,

vtkPointData * inPd,

vtkPointData * outPd,

vtkCellData * inCd,

vtkIdType cellId,

vtkCellData * outCd,

int insideOut

) [virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.

int vtkVertex::EvaluatePosition ( float x[3],

float * closestPoint,

int & subId,

float pcoords[3],

float & dist2,

float * weights

) [virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.

void vtkVertex::EvaluateLocation ( int & subId,

float pcoords[3],

float x[3],

float * weights

) [virtual]

See the vtkCell API for descriptions of these methods.
Implements vtkCell.

int vtkVertex::CellBoundary ( int subId,

float pcoords[3],

vtkIdList * pts

) [virtual]

Given parametric coordinates of a point, return the closest cell boundary, and whether the point is inside or outside of the cell. The cell boundary is defined by a list of points (pts) that specify a vertex (1D cell). If the return value of the method is != 0, then the point is inside the cell.
Implements vtkCell.

void vtkVertex::Contour ( float value,

vtkDataArray * cellScalars,

vtkPointLocator * locator,

vtkCellArray * verts1,

vtkCellArray * lines,

vtkCellArray * verts2,

vtkPointData * inPd,

vtkPointData * outPd,

vtkCellData * inCd,

vtkIdType cellId,

vtkCellData * outCd

) [virtual]

Generate contouring primitives. The scalar list cellScalars are scalar values at each cell point. The point locator is essentially a points list that merges points as they are inserted (i.e., prevents duplicates).
Implements vtkCell.

int vtkVertex::IntersectWithLine ( float p1[3],

float p2[3],

float tol,

float & t,

float x[3],

float pcoords[3],

int & subId

) [virtual]

Intersect with a ray. Return parametric coordinates (both line and cell) and global intersection coordinates, given ray definition and tolerance. The method returns non-zero value if intersection occurs.
Implements vtkCell.

int vtkVertex::Triangulate ( int index,

vtkIdList * ptIds,

vtkPoints * pts

) [virtual]

Triangulate the vertex. This method fills pts and ptIds with information from the only point in the vertex.
Implements vtkCell.

void vtkVertex::Derivatives ( int subId,

float pcoords[3],

float * values,

int dim,

float * derivs

) [virtual]

Get the derivative of the vertex. Returns (0.0, 0.0, 0.0) for all dimensions.
Implements vtkCell.

void vtkVertex::InterpolationFunctions ( float pcoords[3],

float weights[1]

) [static]

Vertex specific methods.
