PARENT CLASS FUNCTIONS
The OpenGL Performer class pfSuperQuadCurve3d is derived from the parent
class pfCurve3d, so each of these member functions of class pfCurve3d are
also directly usable with objects of class pfSuperQuadCurve3d. This is
also true for ancestor classes of class pfCurve3d.
pfReal pfCurve3d::getBeginT()
pfReal pfCurve3d::getEndT()
pfVec3 pfCurve3d::getBeginPt();
pfVec3 pfCurve3d::getEndPt();
pfVec3 pfCurve3d::getBeginTan();
pfVec3 pfCurve3d::getEndTan();
void pfCurve3d::setClosed(int loopVal);
int pfCurve3d::getClosed();
void pfCurve3d::setClosedTol(pfReal tol);
pfReal pfCurve3d::getClosedTol();
virtual void pfCurve3d::evalPt(pfReal t, pfVec3& pnt) = 0;
virtual void pfCurve3d::evalTan(pfReal t, pfVec3& pnt);
virtual void pfCurve3d::evalNorm(pfReal t, pfVec3& pnt);
virtual void pfCurve3d::evalCurv(pfReal t, pfReal& curv);
void pfCurve3d::eval(pfReal t, pfVec3 &pnt, pfVec3 &tan,
pfReal &curv, pfVec3 &norm)
Since the class pfCurve3d is itself derived from the parent class pfRep,
objects of class pfSuperQuadCurve3d 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 pfSuperQuadCurve3d can also be used with these functions
designed for objects of class pfGeode.
int pfGeode::addGSet(pfGeoSet* gset);
int pfGeode::removeGSet(pfGeoSet* gset);
int pfGeode::insertGSet(int index, pfGeoSet* gset);
int pfGeode::replaceGSet(pfGeoSet* old, pfGeoSet* new);
pfGeoSet * pfGeode::getGSet(int index);
int pfGeode::getNumGSets(void);
Since the class pfGeode is itself derived from the parent class pfNode,
objects of class pfSuperQuadCurve3d can also be used with these functions
designed for objects of class pfNode.
pfGroup * pfNode::getParent(int i);
int pfNode::getNumParents(void);
void pfNode::setBound(pfSphere *bsph, int mode);
int pfNode::getBound(pfSphere *bsph);
pfNode* pfNode::clone(int mode);
pfNode* pfNode::bufferClone(int mode, pfBuffer *buf);
int pfNode::flatten(int mode);
int pfNode::setName(const char *name);
const char * pfNode::getName(void);
pfNode* pfNode::find(const char *pathName, pfType *type);
pfNode* pfNode::lookup(const char *name, pfType* type);
int pfNode::isect(pfSegSet *segSet, pfHit **hits[]);
void pfNode::setTravMask(int which, uint mask, int setMode,
int bitOp);
uint pfNode::getTravMask(int which);
void pfNode::setTravFuncs(int which, pfNodeTravFuncType pre,
pfNodeTravFuncType post);
void pfNode::getTravFuncs(int which, pfNodeTravFuncType *pre,
pfNodeTravFuncType *post);
void pfNode::setTravData(int which, void *data);
void * pfNode::getTravData(int which);
void pfNode::setTravMode(int which, int mode, int val);
int pfNode::getTravMode(int which, int mode) const;
Since the class pfNode is itself derived from the parent class pfObject,
objects of class pfSuperQuadCurve3d can also be used with these functions
designed for objects of class pfObject.

void pfObject::setUserData(int slot, void *data);
void* pfObject::getUserData(pfObject *obj);
void* pfObject::getUserData(pfObject *obj, int slot);
int pfObject::getNumUserData();
Since the class pfObject is itself derived from the parent class
pfMemory, objects of class pfSuperQuadCurve3d can also be used with these
functions designed for objects of class pfMemory.
void* pfMemory::getData(const void *ptr);
pfType * pfMemory::getType();
int pfMemory::isOfType(pfType *type);
int pfMemory::isExactType(pfType *type);

DESCRIPTIONpfSuperQuadCurve3d defines a three-dimensional parametric curve as the
following:
x(t) = radius * sign(cos(t)) * pow(|cos(t)|, exponent);
y(t) = radius * sign(sin(t)) * pow(|sin(t)|, exponent);
z(t) = 0.0;
The curve is subject to the transformation of the matrix orientation and
translation of origin, which are inherited members from class pfRep.
pfSuperQuadCurve3d::getClassType returns the pfType* for the class
pfSuperQuadCurve3d. The pfType* returned by
pfSuperQuadCurve3d::getClassType is the same as the pfType* returned by
invoking the virtual function getType on any instance of class
pfSuperQuadCurve3d. 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.
pfSuperQuadCurve3d::pfSuperQuadCurve3d() creates an instance of an
pfSuperQuadCurve3d. The radius is initialized to 1, exponent is
initialized to 2, beginT is initialized to 0 and endT is initialized to
2*pi.
pfSuperQuadCurve3d::pfSuperQuadCurve3d(pfReal rad,pfVec3 *org,pfReal
expn) creates an instance of a pfSuperQuadCurve3d. radius is set to rad,
exponent is set to expn, origin is set to org, beginT is set to 0 and
endT is set to 2*pi.
pfSuperQuadCurve3d::setRadius sets the radius value.
pfSuperQuadCurve3d::getRadius returns the radius value.
pfSuperQuadCurve3d::setExponent sets the exponent value.
pfSuperQuadCurve3d::getExponent returns the radius value.
pfSuperQuadCurve3d::evalPt Evaluates the curve at parameter t. The
resulting point is store in pnt.
