Re: [osg-users] Retrieving Z-Near Far per-frame
Hi Randal,
it is easy . somewhere in the loop, probably after the frame all you
have to do is to get the projection matrix like
while (!viewer.done())
{
viewer.frame();
viewer.getCamera()-getProjectionMatrixAsFrustum(arguments )

Is there (I'm sure there is) a way to retrieve the autocalculated ZNear
ZFar from the scene graph on a per-frame basis? I figure it's somewhere in
a traversal structure, but I'm not exactly sure where or how to get to it.
Can someone enlighten me?

Re: [osg-users] Retrieving Z-Near Far per-frame
You might take a look at the osgthirdpersonview example, which draws two views of the same scene, one of which contains a wireframe representation of the view frustum used for the other view.
