Detailed Description

a 3D cell that represents a linear pyramid

vtkPyramid is a concrete implementation of vtkCell to represent a 3D pyramid. A pyramid consists of a rectangular base with four triangular faces. vtkPyramid uses the standard isoparametric shape functions for a linear pyramid. The pyramid is defined by the five points (0-4) where (0,1,2,3) is the base of the pyramid which, using the right hand rule, forms a quadrilaterial whose normal points in the direction of the pyramid apex at vertex #4.

Member Function Documentation

static vtkPyramid* vtkPyramid::New ( ) [static]

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

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

Reimplemented from vtkCell3D.

static int vtkPyramid::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 vtkCell3D.

virtual int vtkPyramid::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 vtkCell3D.

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

Reimplemented from vtkCell3D.

void vtkPyramid::PrintSelf ( ostream & os,

vtkIndent indent

) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkCell3D.

virtual void vtkPyramid::GetEdgePoints ( int edgeId,

int *& pts

) [virtual]

See vtkCell3D API for description of these methods.
Implements vtkCell3D.

virtual void vtkPyramid::GetFacePoints ( int faceId,

int *& pts

) [virtual]

Get the list of vertices that define a face. The list is terminated with a negative number. Note that the vertices are 0-offset; that is, they refer to the ids of the cell, not the point ids of the mesh that the cell belongs to. The faceId must range between 0<=faceId<this->GetNumberOfFaces().
Implements vtkCell3D.
