Detailed 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.

SoPrimitiveVertex::SoPrimitiveVertex

)

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

SoPrimitiveVertex() [2/2]

SoPrimitiveVertex::SoPrimitiveVertex

(

const SoPrimitiveVertex &

pv

The pointer may be NULL, although it is set to NULL during construction.
