Detailed Description
The SoFaceDetail class is for storing detailed polygon information.
Instances of this class are used among other things for storing information about polygons after pick operations, and for storing information returned to tessellation callbacks.
Note that a SoFaceDetail instance consists of a set of SoPointDetail instances, one for each vertex of the polygon it represents.

Constructor & Destructor Documentation
SoFaceDetail::SoFaceDetail (void)
Default constructor sets up an empty, non-valid detail specification.
SoFaceDetail::~SoFaceDetail () [virtual]
Destructor, free internal resources used for storing the polygon vertices.
Member Function Documentation
SoType SoFaceDetail::getTypeId (void) const [virtual]
Returns the type identification of an object derived from a class inheriting SoDetail. This is used for runtime type checking and 'downward' casting.
Implements SoDetail.
SoType SoFaceDetail::getClassTypeId (void) [static]
This static method returns the SoType object associated with objects of this class.
static void SoFaceDetail::cleanupClass (void) [inline], [static]
This static method cleans up static data of the class.
SoDetail * SoFaceDetail::copy (void) const [virtual]
Return a deep copy of ourself.
Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make sure that both the Coin DLL and the application executable are using the same instance of a C Run-Time (CRT) library. Otherwise, you will get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes.
Implements SoDetail.
int SoFaceDetail::getNumPoints (void) const
Number of vertices making up the polygon.
const SoPointDetail * SoFaceDetail::getPoint (const int idx) const
Returns a pointer into the array of vertices, starting at the idx'th vertex of the polygon.
The array will contain (SoFaceDetail::getNumPoints() - idx) elements.
SoPointDetail * SoFaceDetail::getPoints (void)
Returns the full array of vertices details for the polygon. The array will contain SoFaceDetail::getNumPoints() elements.
int SoFaceDetail::getFaceIndex (void) const
Returns the index of this polygon within the faceset node it is part of.
int SoFaceDetail::getPartIndex (void) const
If this SoFaceDetail represents a triangle tessellated from a complex shape, this method returns the index of the part of the complex shape it was tessellated from.
void SoFaceDetail::setNumPoints (const int num)
Used internally from library client code setting up a SoFaceDetail instance.

getNumPoints()
void SoFaceDetail::setPoint (const int idx, const SoPointDetail *const detail)
Used internally from library client code setting up a SoFaceDetail instance.
- See also
getPoint(), getPoints()
void SoFaceDetail::setFaceIndex (const int idx)
Used internally from library client code setting up a SoFaceDetail instance.
- See also
getFaceIndex()
void SoFaceDetail::setPartIndex (const int idx)
Used internally from library client code setting up a SoFaceDetail instance.
- See also
getPartIndex()
void SoFaceDetail::incFaceIndex (void)
Used internally from library client code setting up a SoFaceDetail instance.
This function is specific for Coin, and is not present in SGI/TGS Open Inventor.
void SoFaceDetail::incPartIndex (void)
Used internally from library client code setting up a SoFaceDetail instance.
This function is specific for Coin, and is not present in SGI/TGS Open Inventor.
