An A3DRiPointSet is a set of 3D points.
When the A3DRiPointSetGet function populates an A3DRiPointSetData structure, it allocates arrays of coordinates. When you no longer need the A3DRiPointSetData structure, invoke the A3DRiPointSetGet function with the first argument set to NULL to free its allocated memory.
Sample code
A3DInt32 iErr = A3D_SUCCESS; A3DRiPointSet pA3DRiPointSet = NULL; /* Should call something here in order to get a valid A3DRiPointSet */ A3DRiPointSetData sData; A3D_INITIALIZE_DATA(sData); iErr = A3DRiPointSetGet( pA3DRiPointSet , &sData ); if ( iErr == A3D_SUCCESS ) { for (A3DUns32 ui=0;ui<sData.m_uiSize;ui++) { /* Insert here your own code to use PointSet data : sData.m_pdX[ui], sData.m_pdY[ui], sData.m_pdZ[ui] */ } iErr = A3DRiPointSetGet( NULL, &sData ); }
