Detailed Description

cell represents a parabolic, 8-node isoparametric quad

vtkQuadraticQuad is a concrete implementation of vtkNonLinearCell to represent a two-dimensional, 8-node isoparametric parabolic quadrilateral element. 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. The ordering of the eight points defining the cell are point ids (0-3,4-7) 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).

Member Function Documentation

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

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

Reimplemented from vtkObject.

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

Reimplemented from vtkNonLinearCell.

static int vtkQuadraticQuad::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 vtkNonLinearCell.

virtual int vtkQuadraticQuad::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 vtkNonLinearCell.

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

Reimplemented from vtkNonLinearCell.

void vtkQuadraticQuad::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.
