Hi,
I use OSG 2.0 now, and it's much better than other versions. But I meet a
problem when I want to unproject my clicked point from screen to the world
scene.
In OSG 1.0, I use osgUtil::SceneView::getViewport() to get current viewport
matrix and use osgUtil::SceneView::projectWindowXYIntoObject() to get the
near point and far point, then I can use them to get a linesegment to intersect
with any plane.
In OSG 2.0 I use osgViewer::Viewer, I can use
osgViewer::Viewer::getCamre()->getViewport() to get current viewport matrix,
but I don't know how to use
some unproject function like projectWindowXYIntoObject().
I find osgViewer::Viewer has _sceneViews as a osgUtil::SceneView member, but
I can not find and "getSceneView()" method in osgViewer::Viewer.
Can someone give me a hand?
Thanks.
--LiTing.
