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() [1/2]

SoPrimitiveVertex::SoPrimitiveVertex ( void  )

Default constructor, sets up a "void" instance.

◆ SoPrimitiveVertex() [2/2]

SoPrimitiveVertex::SoPrimitiveVertex ( const SoPrimitiveVertex &  pv)

Copy constructor. Does a shallow copy.

See also
SoPrimitiveVertex::operator=()

◆ ~SoPrimitiveVertex()

SoPrimitiveVertex::~SoPrimitiveVertex ( void  )

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

Member Function Documentation

◆ operator=()

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.

◆ getPoint()

const SbVec3f & SoPrimitiveVertex::getPoint ( void  ) const
inline

Returns vertex coordinates, positioned in object space.

◆ getNormal()

const SbVec3f & SoPrimitiveVertex::getNormal ( void  ) const
inline

Returns normal vector, oriented in object space.

◆ getTextureCoords()

const SbVec4f & SoPrimitiveVertex::getTextureCoords ( void  ) const
inline

Returns texture coordinates for vertex, specified in object space.

◆ getMaterialIndex()

int SoPrimitiveVertex::getMaterialIndex ( void  ) const
inline

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

◆ getPackedColor()

uint32_t SoPrimitiveVertex::getPackedColor ( void  ) const
inline

Returns the rgba packed color for the given vertex.

Since
Coin 3.0

◆ getDetail()

const SoDetail * SoPrimitiveVertex::getDetail ( void  ) const
inline

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

◆ setPoint() [1/2]

void SoPrimitiveVertex::setPoint ( const SbVec3f &  pt)
inline

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

◆ setPoint() [2/2]

void SoPrimitiveVertex::setPoint ( float  x,
float  y,
float  z 
)
inline

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

◆ setNormal() [1/2]

void SoPrimitiveVertex::setNormal ( const SbVec3f &  n)
inline

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

◆ setNormal() [2/2]

void SoPrimitiveVertex::setNormal ( float  nx,
float  ny,
float  nz 
)
inline

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

◆ setTextureCoords() [1/5]

void SoPrimitiveVertex::setTextureCoords ( const SbVec2f &  texcoords)
inline

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.

◆ setTextureCoords() [2/5]

void SoPrimitiveVertex::setTextureCoords ( float  tx,
float  ty 
)
inline

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.

◆ setTextureCoords() [3/5]

void SoPrimitiveVertex::setTextureCoords ( const SbVec3f &  texcoords)
inline

Covenience function. Will fill in 1 in the last coord.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since
Coin 2.0

◆ setTextureCoords() [4/5]

void SoPrimitiveVertex::setTextureCoords ( float  tx,
float  ty,
float  tz 
)
inline

Covenience function. Will fill in 1 in the last coord.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since
Coin 2.5

◆ setTextureCoords() [5/5]

void SoPrimitiveVertex::setTextureCoords ( const SbVec4f &  texcoords)
inline

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

◆ setMaterialIndex()

void SoPrimitiveVertex::setMaterialIndex ( int  index)
inline

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

◆ setPackedColor()

void SoPrimitiveVertex::setPackedColor ( uint32_t  rgba)
inline

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

◆ setDetail()

void SoPrimitiveVertex::setDetail ( SoDetail *  detail)
inline

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.
