Member Function Documentation

SbBool SoPrimitiveVertexCache::isValid (const SoState * state) const [virtual]

Return TRUE if this cache is valid, FALSE otherwise.

Reimplemented from SoCache.

void SoPrimitiveVertexCache::close (SoState * state)

Closes the cache after it is created. Takes care of SoGLLazyElement synchronization.
