Hi, I'm trying to implement a custom osg::Drawable which need to check the depth component of a certain pixel before rendering itself. The problem is, glReadPixels always returns 1.0 (even for the entire viewport, which obviously should not be possible). I didn't touch the default settings of depth test/range. Can anyone guess what the problem might be?
...
