[osg-users] OpenSceneGraph 3.0 for beginners book Quality
Hi all, I want to learn how to use OSG. I'm new, I know the basics of OpenGL and I've studied Computer Graphics at the university. I found the book [b]OpenSceneGraph 3.0 for beginners[\b] but I noticed that it has been published in 2010, so it's very old... Is it still a good starting point? is there something more updated? Thank you!

[osg-users] Questions about using OSG.
To whom it may concern, I have a group of basic startup questions about use of the OSG C++ 3D graphics library. -Is it compatible with Windows, Android, Max, Linux? -Are prebuilt 64 bit Windows .dlls available for download? -It it easily compatible with WXWidgets? -Can I use it to load and display/manipulate my model objects from Blender 3D? -IS OSG a low level C functions library like OpenGL, or is it a higher level C++, one like Java 3D for example, where everything is clearly named? -Can I avoid use of Shaders quite entirely and systematically, all whatsoever, when programming via OSG? Yours truly, poweruserm. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OSG and Xinerama
In case this helps someone else, here are the variables that Robert referred to: OSG_CONFIG_FILE - set to a filename where a configuration is read. I'm still trying to determine the format of this. OSG_SCREEN - Set to a screen number. Under Linux it appears to refer to an X11 screen number (seems like it would be more useful to be an Xinerama screen number, though). OSG_WINDOW - Same as using --window. Set to 4 values separated by spaces: x y w h; where x and y give the origin of the window and w and h is the size of the window. The window will have decorations (window bar etc.) OSG_BORDERLESS_WINDOW - same as OSG_WINDOW but without a border. This is what I was originally looking for.
