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

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.

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 is 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 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 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.

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.
