Hello,
I am loading an obj file using OpenSG build-in loader and then using several
graph operator as follows:
SplitGraphOp *spo = new SplitGraphOp;
spo->setMaxPolygons(1000);
/*
To optimize the geometry we create a graph operator
*/
GraphOpSeq *graphOperator = new GraphOpSeq;
//first we verify the geometry
graphOperator->addGraphOp(new VerifyGeoGraphOp);
//merge geometry and transformations
graphOperator->addGraphOp(new MergeGraphOp);
//merge identical field containers
graphOperator->addGraphOp(new SharePtrGraphOp);
//split graph operator
graphOperator->addGraphOp(spo);
//verify again
graphOperator->addGraphOp(new VerifyGeoGraphOp);
/*
After the loading the
resulting graph will be
modified using the
specified graph operator
*/
NodePtr utah_teapot =
SceneFileHandler::the().read("bunnySmall.obj",graphOperator);
/*
Check if the data loading
operation was ok or not
*/
if(utah_teapot == NullFC)
{
cout << "Loading the specified file was not possible." << endl;
return NullFC;
}
//set a string name for that node
//we shall use that string to search
setName(utah_teapot,"UTAH_TEAPOT");
//create a plane at the origin
NodePtr bottom = makePlane(25.0, 25.0, 128, 128);
GeometryPtr geoUtah = GeometryPtr::dcast(utah_teapot->getCore());
/*
Check if the dyamic-casting was successful
*/
if(!geoUtah)
{
cout << "The dynamaic casting was not successful" << endl;
return NullFC;
}
The program crashes saying "The dynamaic casting was not successful". I
checked that if i disable the SplitGraphoperator the program runs fine.
By the way the model that i m loading is large.
Any idea from any one how to how to get around that problem?
Cheers
Sajjad
