Member Function Documentation

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

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

Reimplemented from vtkObject.

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

Reimplemented from vtkCell.

static int vtkTriangle::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 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 ( vtkObject * o ) [static]

Reimplemented from vtkCell.

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.

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