Hi Gerrit
Here is the code. I think there is some sort of coding mistake
NodeRefPtr cone = SceneFileHandler::the()->read(image);
Geometry* geo = (Geometry*)node->getCore();
if (geo == NULL) return 0;
GeoVectorPropertyRecPtr pos = geo->getPositions();
GeoIntegralPropertyUnrecPtr posIndex =
geo->getIndex(Geometry::PositionsIndex);
if (pos == NULL || posIndex == NULL) return 0;
for (UInt32 i=0; i<pos->getSize(); ++i)
{
OSG::Pnt3f p;
pos->getValue(p, i);
// use this vertex here or push some where
}
for (UInt32 i=0; i<posIndex->getSize(); i+=3)
{
int value=0;
posIndex->getValue(value,i);
faces.push_back(value);
posIndex->getValue(value,i+1);
faces.push_back(value);
posIndex->getValue(value,i+2);
faces.push_back(value);
}
This psuecode for refereance. Please tell me if i am doing anything wrong
