Detailed Description

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.

Constructor & Destructor Documentation

SoPrimitiveVertex() [1/2]

SoPrimitiveVertex::SoPrimitiveVertex

(

)

Default constructor.

SoPrimitiveVertex() [2/2]

SoPrimitiveVertex::SoPrimitiveVertex

(

const SoPrimitiveVertex &

pv

)

Constructor.

Note that copying a primitive vertex copies the detail pointer, and not the detail itself.

~SoPrimitiveVertex()

SoPrimitiveVertex::~SoPrimitiveVertex

(

)

Destructor.

Member Function Documentation

getDetail()

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.

Definition at line 151 of file SoPrimitiveVertex.h.

getMaterialIndex()

int SoPrimitiveVertex::getMaterialIndex ( ) const

inline

Returns the index into the current set of materials of the material active at the vertex.

Definition at line 139 of file SoPrimitiveVertex.h.

getNormal()

const SbVec3f & SoPrimitiveVertex::getNormal ( ) const

inline

Returns the normal in object space.

Definition at line 129 of file SoPrimitiveVertex.h.

getPoint()

const SbVec3f & SoPrimitiveVertex::getPoint ( ) const

inline

Returns the surface point in object space.

Definition at line 125 of file SoPrimitiveVertex.h.

getPointDetail()

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.

Definition at line 145 of file SoPrimitiveVertex.h.

getTextureCoords()

const SbVec4f & SoPrimitiveVertex::getTextureCoords

(

)

const

Returns the texture coordinates in object space.

operator=()

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.
