PARENT CLASS FUNCTIONS
The OpenGL Performer class pfLine3d is derived from the parent class
pfCurve3d, so each of these member functions of class pfCurve3d are also
directly usable with objects of class pfLine3d. This is also true for
ancestor classes of class pfCurve3d.

Since the class pfCurve3d is itself derived from the parent class pfRep,
objects of class pfLine3d can also be used with these functions designed
for objects of class pfRep.
void pfRep::setOrigin(const pfVec3 *origin);
void pfRep::setOrient(const pfMatrix *mat);
void pfRep::getOrigin(pfVec3& origin);
void pfRep::getOrient(pfMatrix& matrix);
Since the class pfRep is itself derived from the parent class pfGeode,
objects of class pfLine3d can also be used with these functions designed
for objects of class pfGeode.

objects of class pfLine3d can also be used with these functions designed
for objects of class pfNode.

objects of class pfLine3d can also be used with these functions designed
for objects of class pfObject.

DESCRIPTION
A three-dimensional parametric line is defined by two points in 3D space
and parametric space, so that the spatial (x,y,z) and parametric, t,
values vary linearly from one point to the other.
pfLine3d::getClassType returns the pfType* for the class pfLine3d. The
pfType* returned by pfLine3d::getClassType is the same as the pfType*
returned by invoking the virtual function getType on any instance of
class pfLine3d. 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 the member function isOfType 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.

pfLine3d(3pf) OpenGL Performer 3.2.2 libpf C++ Reference Pages pfLine3d(3pf)pfLine3d::pfLine3d() creates an instance of an pfLine3d. By default the
parametric domain is defined as [0..1].
pfLine3d::pfLine3d(pfReal x1,pfReal y1,pfReal z1,pfReal t1,pfReal
x2,pfReal z2,pfReal y2,pfReal t2) creates an instance of a pfLine3d
starting at p1=(x1,y1,z1) and ending at p2=(x2,y2,z2), parametrized from
t1 to t2.
The Line's parametric space is chosen such that when it is evaluated at
t1, p1 is returned and when it is evaluated at t2, p2 is returned.
pfLine3d::setPoint1 Sets the first endpoint of the line as per the above
description.
pfLine3d::setPoint2 Sets the second endpoint of the line as per the above
description.
pfLine3d::getPoint1 returns the values set by ::setPoint1.
pfLine3d::getPoint2 returns the values set by ::setPoint2.
pfLine3d::evalPt Evaluates the line at parametric value t. The evaluator
performs linear extrapolation of the line when the values of t are
outside the domain of t1 and t2.
