They apparently didn't have. I then tried using data from the OpenSceneGraph-Data/Images/tree0.rgba which has alpha values. At this stage I am just interested in seeing a solid block. Here is what I did. I made copies of tree0.rgba file to say, tree1.rgba and: $ osgvolumed --images tree0.rgba tree1.rgba I still don't see a solid block. The result is still like a single slice. Do I have to specify a direction to stack images on? Thanks. > > On Dec 11, 2007 9:07 PM, R. Aditya Kadambi <[EMAIL PROTECTED]> wrote: > > I am trying to use it like this now.
