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]

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.
