Detailed Description

a 3D cell that represents a tetrahedron

vtkTetra is a concrete implementation of vtkCell to represent a 3D tetrahedron. vtkTetra uses the standard isoparametric shape functions for a linear tetrahedron. The tetrahedron is defined by the four points (0-3); where (0,1,2) is the base of the tetrahedron which, using the right hand rule, forms a triangle whose normal points in the direction of the fourth point.

Member Function Documentation

static vtkTetra* vtkTetra::New ( )

static

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

Reimplemented from vtkObject.

virtual const char* vtkTetra::GetClassName ( )

virtual

Reimplemented from vtkCell3D.

static int vtkTetra::IsTypeOf ( const char * name )

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 vtkCell3D.

virtual int vtkTetra::IsA ( const char * name )

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 vtkCell3D.

static vtkTetra* vtkTetra::SafeDownCast ( vtkObject * o )

static

Reimplemented from vtkCell3D.

void vtkTetra::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 vtkTetra::GetEdgePoints	(	int	edgeId,
		int *&	pts
	)

virtual

See vtkCell3D API for description of these methods.

Implements vtkCell3D.

virtual void vtkTetra::GetFacePoints	(	int	faceId,
		int *&	pts
	)
