Detailed DescriptionThe 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 (void)Destructor​. The detail instance is owned by client code and will not be destructed here​.

Member Function Documentation

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​.

const SbVec3f & SoPrimitiveVertex::getPoint (void) const [inline]Returns vertex coordinates, positioned in object space​.

const SbVec3f & SoPrimitiveVertex::getNormal (void) const [inline]Returns normal vector, oriented in object space​.

const SbVec4f & SoPrimitiveVertex::getTextureCoords (void) const [inline]Returns texture coordinates for vertex, specified in object space​.

int SoPrimitiveVertex::getMaterialIndex (void) const [inline]Returns index of the vertex into the currently active material, if any​.

uint32_t SoPrimitiveVertex::getPackedColor (void) const [inline]Returns the rgba packed color for the given vertex​. Since Coin 3​.0

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​.

void SoPrimitiveVertex::setPoint (const SbVec3f & pt) [inline]Used internally from library client code setting up an SoPrimitiveVertex instance​.

void SoPrimitiveVertex::setPoint (float x, float y, float z) [inline]Used internally from library client code setting up an SoPrimitiveVertex instance​.

void SoPrimitiveVertex::setNormal (const SbVec3f & n) [inline]Used internally from library client code setting up an SoPrimitiveVertex instance​.

void SoPrimitiveVertex::setNormal (float nx, float ny, float nz) [inline]Used internally from library client code setting up an SoPrimitiveVertex instance​.

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​.

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​.

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

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

void SoPrimitiveVertex::setTextureCoords (const SbVec4f & texcoords) [inline]Used internally from library client code setting up an SoPrimitiveVertex instance​.

void SoPrimitiveVertex::setMaterialIndex (int index) [inline]Used internally from library client code setting up an SoPrimitiveVertex instance​.

void SoPrimitiveVertex::setPackedColor (uint32_t rgba) [inline]Used internally from library client code setting up an SoPrimitiveVertex instance​.

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​.
