What do you mean by a degenerated polytope of volume 0 ? That polytope
definitely doesn't have a null volume since I've been using it to select

Hi TM,
Erm don't get too excited, like I say I've only added the test cases onto a
sandbox directory on the svn.. Really all that is a new mipmapgeometry class
that supports shader positioning and a cobbled together test case that
updates the primitive levels. I haven't actually merged the code
Hi Peter,
This has come up a couple of times actually. It would be feasible I think
with the new method of updating the tile positions that I've added to the
sandbox.
Whilst I haven't put a lot of thought into it, I'm thinking that
the ellipsoid distortion could be added to tiles within the
Hi All,
I have run in to some trouble with a shader that uses a dynamically
updated uniform (updated rarely but it does change). Everything works as
expected on all nvidia cards I have tried but I cannot get it to work on
an ATI card (FirePro V5700). All systems are running WinXP. I know ATIs

Hi,
I've building a project with osg to render a terrain model in quad buffered
stereo. It has been working great so far, and I have managed to achieve plenty
of depth to the scene. The problem I am facing is trying to get some of the
scene to appear out of the screen floating in front of the

That's probably a generic Windows error, and not something I could fix. In
any case the plan is to get rid of the expat dependency anyway and embed
something like tinyxml instead, making the problem moot.
