Re: [osg-users] Getting the List of Triangles from an osg model

[Sanat Talmaki]

Hi,

I was running a small test program to understand the concept a little better:


Code:
int main()
{
  int numChildren, num1, num2, num3;
  const char* geodeName;
  const char* cowChildrenName;
  osg::Group* root = new osg::Group();
  osg::Node* cow = osgDB::readNodeFile("cow.osg");
  
  root->addChild(cow);  
  geodeName = cow->asGroup()->getChild(0)->className();
  numChildren = root->getNumChildren();  
  num1 = cow->asGroup()->getChild(0)->asGeode()->getNumDrawables();  
  num2 = cow->asGroup()->getNumChildren();
  num3 = cow->asGeode()->getNumDrawables();
  _getch();
  
  return 0;
}



The cow Node has 1 child i.e. a Geode. But when I try and query it for number 
of drawables using the line  num3 = cow->asGeode()->getNumDrawables(); I get an 
exception error.

So how do I query it or get the number of drawables ?

Thanks.

Sincerely,
Sanat.
