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::SoFaceDetail ( void )

Default constructor sets up an empty, non-valid detail specification.

◆ ~SoFaceDetail()

SoFaceDetail::~SoFaceDetail ( )

virtual

Destructor, free internal resources used for storing the polygon vertices.

Member Function Documentation

◆ cleanupClass()

static void SoFaceDetail::cleanupClass ( void )

inlinestatic

This static method cleans up static data of the class.

◆ copy()

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.

◆ getClassTypeId()

SoType SoFaceDetail::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

◆ getFaceIndex()

int SoFaceDetail::getFaceIndex ( void ) const

Returns the index of this polygon within the faceset node it is part of.

◆ getNumPoints()

int SoFaceDetail::getNumPoints ( void ) const

Number of vertices making up the polygon.

◆ getPartIndex()

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.

◆ getPoint()

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.

◆ getPoints()

SoPointDetail * SoFaceDetail::getPoints ( void )

Returns the full array of vertices details for the polygon. The array will contain SoFaceDetail::getNumPoints() elements.

◆ getTypeId()

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.
