Hi Mario > Open Scene Graph is an open source (LGPL) C++ alternative to Java3D. Does > anyone know how these two stack up against each other both in performance > and functionality. Has anyone worked with it? How well are they progressing
Yes I'm currently working also with OpenSceneGraph. It's nice, it's very close to SGI Performer except of the states. You can also define your own rendering states and can therefore access directly to OpenGL and have access to Vertex/PixelShaders. All OpenGL1.3 features are supported. It has implemented GLUT for viewing and windowmanagement. It has not a complicated viewing model as J3D. This also means it might not suitable without rewriting parts of OSG for other environments than normal desktop. Performance is good, especially when you tell it to use display lists I would say it's a better than J3D (but that's natural there is no JNI inbetween). What's nice OpenSceneGraph has a performance meter which tells you the current frame/sec and in which parts how many time is spend. Also for terrain freaks (there seem to be a lot in this list) it has Imposter build-in. And it's available for Win32,Linux,Irix,MacOS X What's weak: - Documentation (there is nearly one, so if you don't have any clue about Scenegraphs, you're lost) - No Behaviour nodes, this means bad for animations (you have to write that yourself).
