Hi,
I have written a viewer on Window XP using MFC based on osviewerMFC example
code. I add eighteen IVE-format models(about 1.15GB on harddisk) as children
node to the scene's root group node, then, the rendering process gives a sharp
slowdown and the FPS decrease to less than 1.0 . Could anyone give me some help
on how to enhance the rendering performance?
I am using OSG 2.0. The code I used to add a IVE-format model to scene is:
......
// Load the model from the model name
osg::ref_ptr<osg::Node> m_pNewModel;
m_pNewModel = osgDB::readNodeFile(strModel.GetString()); //strModel is
CString variable contains the model's full path.
if (m_pNewModel.get())
{
osgUtil::Optimizer optimizer;
optimizer.optimize(m_pNewModel.get());
optimizer.reset();
// Add the model to the scene
mRoot->addChild(m_pNewModel.get());
//mRoot is the scene's root node defined as osg::ref_ptr<osg::Group>
}
......
