Hi robertosfield and hybr,
Thanks a lot for the nice help.
My develop environment is windows XP 32 bit with SP3. On 32 bit machines the
code works well.
When I run on Win - 7 Ultimate 64 bit then I am getting run time error some
times. I dont have development environment on 64 bit machine. I don't know how
to provide stack trace on this testing machine.
I modified my code such that the thread has only reading statement. I want to
run all threads simultaneously (so reading will be fast). I dont want sysnc of
threads.
Here is my modified code.
Code:
//Globles
struct ModelObj
{
int id;
};
ModelObj obj[NUM_OF_MODELS];
Model model;//OBJ OF MODEL HANDLING CLASS
HANDLE T[NUM_OF_MODELS];
CWinThread *pThread[NUM_OF_MODELS];
UINT ThreadProc1(LPVOID lpvoid)
{
ModelObj *temp = (ModelObj*)lpvoid;
//model.mtForMarker[temp->id] = new osg::MatrixTransform;
//model.modelSwitch->addChild(model.mtForMarker[temp->id].get());
model.modelForMarker[temp->id] = osgDB::readNodeFile(model.fileNames[temp->id]);
if(model.modelForMarker[temp->id])
{
model.mtForMarker[temp->id]->addChild(model.modelForMarker[temp->id].get());
//model.mtForMarker[temp->id]->addChild(model.sound_root.get());
// model.mtForMarker[temp->id]->setUpdateCallback(
model.soundCB.get() );
}
return 0;
}
In main
Code:
Code:
.........
for(int i=0;i<NUM_OF_MODELS;i++)
{
obj[i].id=i;
}
strcpy(model.fileNames[0],"osg_01.osg");
strcpy(model.fileNames[1],"osg_02.OSG");
strcpy(model.fileNames[2],"osg_03.OSG");
DWORD ThreadId[NUM_OF_MODELS];
for(int i=0;i<NUM_OF_MODELS;i++)
{
model.mtForMarker[i] = new osg::MatrixTransform;
model.modelSwitch->addChild(model.mtForMarker[i].get());
model.mtForMarker[i]->addChild(model.sound_root.get());
model.mtForMarker[i]->setUpdateCallback(
model.soundCB.get() );
//pThread[i]=new CWinThread;
std::cout<<"Thread: "<<i<<std::endl;
pThread[i] = AfxBeginThread (ThreadProc1,
(LPVOID)&obj[i]);
pThread[i]->m_bAutoDelete=FALSE;
}
for (int j = 0; j < NUM_OF_MODELS; j ++)
{
T[j] = pThread[j]->m_hThread;
}
::WaitForMultipleObjects(NUM_OF_MODELS, T, TRUE,
INFINITE);
for (int j = 0; j < NUM_OF_MODELS; j ++)
{
delete pThread[j];
}
Once I tried to use binary formats. But when compared to OSG files its size is
huge. So I stopped. I will try once again. (I am changing textures dynamically.
Is it possible with binary formats?)
Can you please guide me how to solve this problem?
...
Thank you!
Cheers,
Koduri
