SoPointDetail.3coin2

NAME

SoPointDetail -

The SoPointDetail class is for storing detailed information for a single 3D point.

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

SYNOPSIS

Detailed Description

The SoPointDetail class is for storing detailed information for a single 3D point.

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

It contains indices into the vertex coordinate sets, along with indices into material, texture and normal coordinates for the point.

Constructor & Destructor Documentation

SoPointDetail::SoPointDetail (void)Sets up an empty detail instance (all indices are equal to 0).

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

Member Function Documentation

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

Reimplemented from SoDetail.

SoDetail * SoPointDetail::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 SoPointDetail::getCoordinateIndex (void) constReturns index into coordinate set for the point's 3D coordinates.

int SoPointDetail::getMaterialIndex (void) constReturns point's index into set of materials.

int SoPointDetail::getNormalIndex (void) constReturns point's index into set of normals.

int SoPointDetail::getTextureCoordIndex (void)Returns point's index into set of texture coordinates.

void SoPointDetail::setCoordinateIndex (const int idx)Used by client code for initializing the point detail instance.
