Frenet swept surface
FUNCTION SPECIFICATION
#include <Performer/pf.h>
pfType * pfGetSweptClassType(void);

void pfFrenetSweptSurfaceSet(pfCurve3d *crossSection,

PARENT CLASS FUNCTIONS
The OpenGL Performer class pfFrenetSweptSurface is derived from the
parent class pfSweptSurface, so each of these member functions of class
pfSweptSurface are also directly usable with objects of class
pfFrenetSweptSurface. Casting an object of class pfFrenetSweptSurface to
an object of class pfSweptSurface is taken care of automatically. This
is also true for casts to objects of ancestor classes of class
pfSweptSurface.
void pfSweptSurfaceCrossSection(pfSweptSurface* ss,
pfCurve3d *crossSection);
void pfSweptSurfacePath(pfSweptSurface* ss, pfCurve3d *path);

pfScalar* pfGetSweptSurfaceProf(pfSweptSurface* ss);
void pfSweptSurfaceEvalPt(pfSweptSurface *ss, pfReal u, pfReal v,

Since the class pfSweptSurface is itself derived from the parent class
pfParaSurface, objects of class pfFrenetSweptSurface can also be used
with these functions designed for objects of class pfParaSurface.

pfGeode, objects of class pfFrenetSweptSurface can also be used with
these functions designed for objects of class pfGeode.

DESCRIPTION
A Frenet swept surface is a special type of swept surface. A general
swept surface is defined in pfFrenetSweptSurface. A Frenet swept surface
uses the tangent and binormal path(u) as t and b which are the inherited
members from the superclass pfSweptSurface and are used to generate the
frame matrix of the swept surface.
pfGetSweptClassType returns the pfType* for the class
pfFrenetSweptSurface. The pfType* returned by pfGetConeClassType is the
same as the pfType* returned by invoking pfGetType on any instance of
class pfFrenetSweptSurface. Because OpenGL Performer allows subclassing
of built-in types, when decisions are made based on the type of an
object, it is usually better to use pfIsOfType to test if an object is of
a type derived from a Performer type rather than to test for strict
equality of the pfType*'s.

pfNewFrenetSweptSurface creates an instance of pfFrenetSweptSurface. No
valid data is set.
pfFrenetSweptSurfaceSet Sets the 3 inherited members. The inherited
member t is set to the tangent path of path and the inherited member b is
set to the binormal of path. Since t and b are both represented as 3d
curves (pfCurve3d), data structures are created for them. See the
Programmer's Guide for additional information.
