Represents a vertex of a generated primitive.
An SoPrimitiveVertex represents a vertex of a primitive (triangle, line segment, or point) that is being generated by an SoCallbackAction. It contains an object-space point, normal, texture coordinates, material index, and refers an instance of an SoDetail subclass. This detail may contain more information about the vertex, or may be NULL if there is no such info.
Instances of SoPrimitiveVertex are typically created on the stack by shape classes while they are generating primitives. Anyone who wants to save them as return values from SoCallbackAction should probably make copies of them.
SoPrimitiveVertex::SoPrimitiveVertex | ( | ) |
Default constructor.
SoPrimitiveVertex::SoPrimitiveVertex | ( | const SoPrimitiveVertex & | pv | ) |
Constructor.
Note that copying a primitive vertex copies the detail pointer, and not the detail itself.
SoPrimitiveVertex::~SoPrimitiveVertex | ( | ) |
Destructor.
const SoDetail* SoPrimitiveVertex::getDetail | ( | ) | const [inline] |
Returns the detail giving more information about the vertex.
Note that the return value is NULL if there is no more info.
int SoPrimitiveVertex::getMaterialIndex | ( | ) | const [inline] |
Returns the index into the current set of materials of the material active at the vertex.
const SbVec3f& SoPrimitiveVertex::getNormal | ( | ) | const [inline] |
Returns the normal in object space.
const SbVec3f& SoPrimitiveVertex::getPoint | ( | ) | const [inline] |
Returns the surface point in object space.
const SoPointDetail* SoPrimitiveVertex::getPointDetail | ( | ) | const [inline] |
Returns the point detail giving more information about the vertex.
Note that the return value is NULL if there is no more info.
const SbVec4f& SoPrimitiveVertex::getTextureCoords | ( | ) | const |
Returns the texture coordinates in object space.
SoPrimitiveVertex& SoPrimitiveVertex::operator= | ( | const SoPrimitiveVertex & | pv | ) |
Copies the given vertex.
Note that just the pointer to the detail is copied, and not the detail itself.
