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 tesselation 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

void SoFaceDetail::initClass (  void )  [static]

Initialize relevant common data for all instances, like the type system. Reimplemented from SoDetail.

SoDetail * SoFaceDetail::copy (  void )  const [virtual]

Return a deep copy of ourself. Reimplemented from 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 vertice of the polygon. The array will contain (SoFaceDetail::getNumPoints() - idx) elements.

SoPointDetail * SoFaceDetail::getPoints (  void )

Returns the full array of vertice 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 tesselated from a complex shape, this method returns the index of the part of the complex shape it was tesselated from.

void SoFaceDetail::setNumPoints (  const int num )

Used internally from library client code setting up a SoFaceDetail instance. See also: 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.

void SoFaceDetail::incPartIndex (  void )

Used internally from library client code setting up a SoFaceDetail instance.
