Detailed Description

a cell that represents a 2D quadrilateral

vtkQuad is a concrete implementation of vtkCell to represent a 2D quadrilateral. vtkQuad is defined by the four points (0,1,2,3) in counterclockwise order. vtkQuad uses the standard isoparametric interpolation functions for a linear quadrilateral.

Member Function Documentation

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

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

Reimplemented from vtkObject.

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

Reimplemented from vtkCell.

static int vtkQuad::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 vtkCell.

virtual int vtkQuad::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 vtkCell.

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

Reimplemented from vtkCell.

void vtkQuad::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 vtkCell.

int vtkQuad::GetCellType ( ) [inline, virtual]
