Detailed Description

cell represents a parabolic, 9-node isoparametric quad

vtkQuadraticQuad is a concrete implementation of vtkNonLinearCell to represent a two-dimensional, 9-node isoparametric parabolic quadrilateral element with a Centerpoint. The interpolation is the standard finite element, quadratic isoparametric shape function. The cell includes a mid-edge node for each of the four edges of the cell and a center node at the surface. The ordering of the eight points defining the cell are point ids (0-3,4-8) where ids 0-3 define the four corner vertices of the quad; ids 4-7 define the midedge nodes (0,1), (1,2), (2,3), (3,0) and 8 define the face center node.

Member Function Documentation

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

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

Reimplemented from vtkObject.

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

Reimplemented from vtkNonLinearCell.

static int vtkBiQuadraticQuad::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkNonLinearCell.

virtual int vtkBiQuadraticQuad::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkNonLinearCell.

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

Reimplemented from vtkNonLinearCell.

void vtkBiQuadraticQuad::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 vtkNonLinearCell.
