Hi Alberto,
About OpenSceneGraph, I think you should first decide if you want it to be run
through an
X-Server, or not (native M$ OpenGL implementation).
If you go down the X-Server road, you will not get hardware/driver acceleration
for now.
It may come in a future release of X11r7, as we had it in XFree86, but I don't
know
what is the roadmap for that. For the X-Server road, you would need libGL1,
libGLU1 and maybe libGLw1
as required packages for your run-time package. You would need libGL1-devel,
libGLU1-devel and maybe libGLw1-devel
as required packages for your developer package. You would _not_ need the
opengl package as a requirement of any
of your package.
If you go down the native OpenGL road, you will get hardware/driver
acceleration, but you will need to load
anything above OpenGL 1.1 dynamically. You would _not_ need the opengl package
as a requirement, as the required DLLs
(opengl32.dll and glu32.dll) are part of M$ Windows. You would need w32api as a
required package for your developper package.
The opengl package provides native implementation of opengl-related libraries
GLUT, GLUI, and GLUIX.
