static int vtkTriangle::IsTypeOf ( const char * type )

static

virtual int vtkTriangle::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 vtkTriangle* vtkTriangle::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkTriangle::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkCell.

vtkTriangle* vtkTriangle::NewInstance ( ) const

void vtkTriangle::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.

vtkCell* vtkTriangle::GetEdge ( int edgeId )

virtual

Get the edge specified by edgeId (range 0 to 2) and return that edge's coordinates.

Implements vtkCell.
