Detailed Description

a cell that represents a 3D orthogonal parallelepiped

vtkVoxel is a concrete implementation of vtkCell to represent a 3D orthogonal parallelepiped. Unlike vtkHexahedron, vtkVoxel has interior angles of 90 degrees, and sides are parallel to coordinate axes. This results in large increases in computational performance.

Member Function Documentation

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

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

Reimplemented from vtkObject.

static int vtkVoxel::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 vtkCell3D.

virtual int vtkVoxel::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 vtkCell3D.

static vtkVoxel* vtkVoxel::SafeDownCast ( vtkObjectBase o) [static]

Reimplemented from vtkCell3D.

virtual vtkObjectBase* vtkVoxel::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkCell3D.

Reimplemented from vtkCell3D.

void vtkVoxel::PrintSelf ( ostream &  os,
vtkIndent  indent
