Detailed Description

a cell that represents a linear 3D hexahedron

vtkHexahedron is a concrete implementation of vtkCell to represent a linear, 3D rectangular hexahedron (e.g., "brick" topology). vtkHexahedron uses the standard isoparametric shape functions for a linear hexahedron. The hexahedron is defined by the eight points (0-7) where (0,1,2,3) is the base of the hexahedron which, using the right hand rule, forms a quadrilaterial whose normal points in the direction of the opposite face (4,5,6,7).

Member Function Documentation

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

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

Reimplemented from vtkObject.

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

Reimplemented from vtkCell3D.

static int vtkHexahedron::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 vtkHexahedron::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 vtkHexahedron* vtkHexahedron::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkCell3D.

void vtkHexahedron::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 vtkHexahedron::GetEdgePoints	(	int	edgeId,
		int *&	pts
	)			`[virtual]`

See vtkCell3D API for description of these methods.

Implements vtkCell3D.

virtual void vtkHexahedron::GetFacePoints	(	int	faceId,
		int *&	pts
	)			`[virtual]`

See vtkCell3D API for description of these methods.

Implements vtkCell3D.
