hi
It got some probleme in opening of huge 3D database files (IVE format). At
the moment the file is first time displayed whe have to
check for 2 different cases:
(1) case would be: the whole file content (scene) is displayed: we rotate
the camera, move the camera and so on, no probleme, the fps stay constant.
on my carte 10fps, you see quite huge
file.
(2) the camera is in the center of the file, and only a small part of the
scene is display: we do same thing manipluating the camera, our movement is
not yet fluid. once we have displayed
the whole file once, part by part the scene is greate working. is there a
problem in transfering datas to the GPU? buffered object, better to use
displaylist?
i am using:
m_sceneView->setDefaults(mode|osgUtil::SceneView::COMPILE_GLOBJECTS_AT_INIT);
((osgUtil::GLObjectsVisitor*)m_sceneView->getInitVisitor())->setMode(
((osgUtil::GLObjectsVisitor*)m_sceneView->getInitVisitor())->getMode()|
osgUtil::GLObjectsVisitor::SWITCH_ON_VERTEX_BUFFER_OBJECTS
);
regards
adegli
