how to use GU_PackedGeometry::packGeometry

[Arthur~Chiu]

GU_PackedGeometry::packGeometry ( GU_Detail &  dest,     const GU_ConstDetailHandle &  gdh    )

 

i want to pack my polygon or points,someone can help me?

[Arthur~Chiu]

GU_DetailHandle      gdh;

gdh.allocateAndSet(gdp,false);

 

if(gdh.isValid())

{

      

      GU_Detail dddd;

      GU_PrimPacked *pack = GU_PackedGeometry::packGeometry(dddd,gdh);

      //GU_PrimPacked       *pack = GU_PrimPacked::build(*gdp, "PackedSphere");

 

      if (pack)

      {

             gdp->clearAndDestroy();

             gdp->copy(dddd,GEO_COPY_ONCE /*GEO_COPY_ADD GEO_COPY_START*/);

      }

}

 

when add the "gdp->copy(dddd,GEO_COPY_ONCE /*GEO_COPY_ADD GEO_COPY_START*/);" it will error
