BTW, for the sake of your own sanity, I do suggest to use some higher level toolkit (at least SDL) instead of writing directly for X11. You won't get any performance advantage by doing that, but you lose out on much of the functionality. > > I'm interested to have a full control of my camera (position, gaze...) > like I do in Opengl. > > Same for inputs, I'm using X11 key/mouse event.

There are some tutorials included with OSG, but I doubt you will find many dealing with raw X11 - few people are such masochists to use that. However, from your code I can see that you have got the init done correctly, so the rest should be relatively straightforward. > Moreover, I'm bit confused, when I go there : > > http://trac.openscenegraph.org/projects/osg//wiki/Support/Tutorials > > and see many tutorials with some note like : "Code needs conversion to > osgViewer" I don't know if it's not wothless to take time to study these > tutorials... > Um, if you consider tutorials as possibly "worthless" before even looking at them, there isn't much that can be done for you. Only you can say whether or not something helps you, so go and look at those tutorials. OSG comes with plenty of examples too and there are also several books available - the cookbook was mentioned already, there is also a beginners book and quick start guide: http://www.openscenegraph.com/index.php/documentation/books > p.s. : there is a reason why http://trac.openscenegraph.org is so slow ? > That's the old website, use http://www.openscenegraph.com/ instead. Concerning: > as you can see, there is some black parts, I don't know why... (p.s.

That would be best way to check that as your code obviously doesn't work in Windows and on Linux my machine could behave differently than yours (different GPU or drivers, for example). Regards, Jan
