SoLineDetail.3coin2

NAME

SoLineDetail -

The SoLineDetail class is for storing detailed 3D line information.

Instances of this class are used among other things for storing information about lines after pick operations, and for storing information returned to tessellation callbacks.

Constructor & Destructor Documentation

SoLineDetail::SoLineDetail (void)Default constructor sets up an empty, non-valid detail specification.

Referenced by copy().

SoLineDetail::~SoLineDetail () [virtual]Destructor.

Member Function Documentation

void SoLineDetail::initClass (void) [static]Initialize relevant common data for all instances, like the type system.

Reimplemented from SoDetail.

SoDetail * SoLineDetail::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.

const SoPointDetail * SoLineDetail::getPoint0 (void) constReturns SoPointDetail describing the line start point.

const SoPointDetail * SoLineDetail::getPoint1 (void) constReturns SoPointDetail describing the line end point.

int SoLineDetail::getLineIndex (void) constReturns the index of this line within the lineset node it is part of.

int SoLineDetail::getPartIndex (void) constReturns the index of this line within the complex shape node it is part of.

void SoLineDetail::setPoint0 (const SoPointDetail *const detail)Stores information about line's start point. Used internally from library client code setting up a SoLineDetail instance.
