Detailed Description

cell represents a parabolic, isoparametric triangle

vtkQuadraticTriangle is a concrete implementation of vtkNonLinearCell to represent a two-dimensional, 6-node, isoparametric parabolic triangle. The interpolation is the standard finite element, quadratic isoparametric shape function. The cell includes three mid-edge nodes besides the three triangle vertices. The ordering of the three points defining the cell is point ids (0-2,3-5) where id #3 is the midedge node between points (0,1); id #4 is the midedge node between points (1,2); and id #5 is the midedge node between points (2,0).

Member Function Documentation

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

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

Reimplemented from vtkObject.

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

Reimplemented from vtkNonLinearCell.

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

Reimplemented from vtkNonLinearCell.

void vtkQuadraticTriangle::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.
