Detailed Description

The SoPrimitiveVertex class represents a single vertex of a generated primitive.

Instances of SoPrimitiveVertex are constructed when generating primitive data, primarily during an SoCallbackAction traversal. Depending on the context the vertex could represent a single 3D point, one of the two vertices in a line or one of the three vertices in a triangle.


Constructor & Destructor Documentation

SoPrimitiveVertex::SoPrimitiveVertex void
 

Default constructor, sets up a "void" instance.

SoPrimitiveVertex::SoPrimitiveVertex const SoPrimitiveVertex & pv
 

Copy constructor. Does a shallow copy.

See also:
SoPrimitiveVertex::operator=()

SoPrimitiveVertex::~SoPrimitiveVertex
 

Destructor. The detail instance is owned by client code and will not be destructed here.


Member Function Documentation

const SbVec3f & SoPrimitiveVertex::getPoint void const
 

Returns vertex coordinates, positioned in object space.

const SbVec3f & SoPrimitiveVertex::getNormal void const
 

Returns normal vector, oriented in object space.

const SbVec4f & SoPrimitiveVertex::getTextureCoords void const
 

Returns texture coordinates for vertex, specified in object space.

int SoPrimitiveVertex::getMaterialIndex void const
 

Returns index of the vertex into the currently active material, if any.

const SoDetail * SoPrimitiveVertex::getDetail void const
 

Returns pointer to detail instance with more information about the vertex. A detail instance may not be available, and if so NULL is returned.

SoPrimitiveVertex & SoPrimitiveVertex::operator= const SoPrimitiveVertex & pv
 

Copy operator.

When pv is copied into this instance, a shallow copy is made. Ie, only the reference to the detail instance is copied (if any), not the detail itself.

void SoPrimitiveVertex::setPoint const SbVec3f & point
 

Used internally from library client code setting up an SoPrimitiveVertex instance.

void SoPrimitiveVertex::setNormal const SbVec3f & normal
 

Used internally from library client code setting up an SoPrimitiveVertex instance.

void SoPrimitiveVertex::setTextureCoords const SbVec4f & texcoords
 

Used internally from library client code setting up an SoPrimitiveVertex instance.

void SoPrimitiveVertex::setTextureCoords const SbVec2f & texcoords
 

Used internally from library client code setting up an SoPrimitiveVertex instance.

Covenience function. Will fill in 0 and 1 in the last two texture coords in the internal SbVec4f texture coordinate instance.

void SoPrimitiveVertex::setMaterialIndex const int index
 

Used internally from library client code setting up an SoPrimitiveVertex instance.

void SoPrimitiveVertex::setDetail SoDetail *const detail
 

Used internally from library client code setting up an SoPrimitiveVertex instance.

Note that it's the client's responsibility to do the deallocation of the detail instance after the SoPrimitiveVertex instance has gone out of scope.
