DESCRIPTION
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 a pointer to an instance of an SoDetail subclass. This detail
may contain more information about the vertex, or may be a NULL pointer
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.
FUNCTIONSSoPrimitiveVertex * SoPrimVtxCreate()SoPrimitiveVertex * SoPrimVtxCreateCopy(const SoPrimitiveVertex *pv)
void SoPrimVtxDelete(SoPrimVtx *this)
Constructors and destructor. Note that copying a primitive vertex
copies the detail pointer, and not the detail itself.
const SbVec3f * SoPrimVtxGetPt(const SoPrimVtx *this)
const SbVec3f * SoPrimVtxGetNorm(const SoPrimVtx *this)
const SbVec4f * SoPrimVtxGetTexCoords(const SoPrimVtx *this)
These return the surface point, normal, and texture coordinates in
object space.

int SoPrimVtxGetMtlInd(const SoPrimVtx *this)
Returns the index into the current set of materials of the material
active at the vertex.
const SoDetail * SoPrimVtxGetDtl(const SoPrimVtx *this)
Returns the detail giving more information about the vertex. Note
that this pointer may be NULL if there is no more info.
SoPrimitiveVertex * SoPrimVtxCopy(SoPrimVtx *this, const
SoPrimitiveVertex *pv)
Copies the given vertex. Note that just the pointer to the detail is
copied, and not the detail itself.
