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.
SoPrimitiveVertex::SoPrimitiveVertex | ( | void | ) |
Default constructor, sets up a "void" instance.
SoPrimitiveVertex::SoPrimitiveVertex | ( | const SoPrimitiveVertex & | pv | ) |
Copy constructor. Does a shallow copy.
SoPrimitiveVertex::~SoPrimitiveVertex | ( | void | ) |
Destructor. The detail instance is owned by client code and will not be destructed here.
const SbVec3f & SoPrimitiveVertex::getPoint | ( | void | ) | const |
Returns vertex coordinates, positioned in object space.
Referenced by SoShape::invokeLineSegmentCallbacks(), SoShape::invokePointCallbacks(), and SoShape::invokeTriangleCallbacks().
const SbVec3f & SoPrimitiveVertex::getNormal | ( | void | ) | const |
Returns normal vector, oriented in object space.
Referenced by SoShape::invokeLineSegmentCallbacks(), SoShape::invokePointCallbacks(), and SoShape::invokeTriangleCallbacks().
const SbVec4f & SoPrimitiveVertex::getTextureCoords | ( | void | ) | const |
Returns texture coordinates for vertex, specified in object space.
Referenced by SoShape::invokeLineSegmentCallbacks(), SoShape::invokePointCallbacks(), and SoShape::invokeTriangleCallbacks().
int SoPrimitiveVertex::getMaterialIndex | ( | void | ) | const |
Returns index of the vertex into the currently active material, if any.
Referenced by SoVRMLIndexedLineSet::generatePrimitives(), SoShape::invokeLineSegmentCallbacks(), SoShape::invokePointCallbacks(), and SoShape::invokeTriangleCallbacks().
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.
Referenced by SoShape::createPointDetail(), SoAsciiText::createTriangleDetail(), and SoText3::createTriangleDetail().
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 & | pointref | ) |
Used internally from library client code setting up an SoPrimitiveVertex instance.
Referenced by SoVRMLPointSet::generatePrimitives(), SoPointSet::generatePrimitives(), SoTriangleStripSet::generatePrimitives(), SoVRMLIndexedLineSet::generatePrimitives(), SoLineSet::generatePrimitives(), SoFaceSet::generatePrimitives(), SoQuadMesh::generatePrimitives(), SoIndexedTriangleStripSet::generatePrimitives(), SoIndexedFaceSet::generatePrimitives(), SoVRMLIndexedFaceSet::generatePrimitives(), SoAsciiText::generatePrimitives(), SoVRMLExtrusion::generatePrimitives(), SoVRMLText::generatePrimitives(), SoVRMLElevationGrid::generatePrimitives(), SoImage::generatePrimitives(), and SoShape::generateVertex().
