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]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

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 vtkTypeMacro 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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkCell.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkCell.

vtkCell* vtkVertex::MakeObject (    )  [virtual]
 

Make a new vtkVertex object with the same information as this object.

Reimplemented from vtkCell.

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

See the vtkCell API for descriptions of these methods.

Reimplemented from vtkCell.

Definition at line 71 of file vtkVertex.h.

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

See the vtkCell API for descriptions of these methods.

Reimplemented from vtkCell.

Definition at line 72 of file vtkVertex.h.

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

See the vtkCell API for descriptions of these methods.

Reimplemented from vtkCell.

Definition at line 73 of file vtkVertex.h.

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

See the vtkCell API for descriptions of these methods.

Reimplemented from vtkCell.

Definition at line 74 of file vtkVertex.h.

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

See the vtkCell API for descriptions of these methods.

Reimplemented from vtkCell.

Definition at line 75 of file vtkVertex.h.

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

See the vtkCell API for descriptions of these methods.

Reimplemented from vtkCell.

Definition at line 76 of file vtkVertex.h.

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.

Reimplemented from 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.

Reimplemented from vtkCell.

void vtkVertex::EvaluateLocation (  int &    subId,
float    pcoords[3],
float    x[3],
float *    weights
)  [virtual]
 

See the vtkCell API for descriptions of these methods.

Reimplemented from 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.

Reimplemented from 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).

Reimplemented from 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.

Reimplemented from 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.

Reimplemented from 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.

Reimplemented from vtkCell.

void vtkVertex::InterpolationFunctions (  float    pcoords[3],
float    weights[1]
)  [static]
 

Vertex specific methods.
