I am a Java web application developer (mostly server side) since 7 years who recently got interested in game development (i dont know why, maybe i am bored). Today I was looking for frameworks. I read about a few scene graphs and took a look at jMonkeyEngine. It was recommended here and here.
My first goal was to create a simple plane and a sphere which could be moved around using the keyboard. Well, as I mentioned I am a web developer and never programmed anything else so I started with the tutorials of jMonkey. But I wasn't able to get them working. I took a look at the wiki but I noticed that the documentation seems to be very poor, at least compared to what I am used to. I then took a look at a few other scene graph's (also for C++) but they also seem to have an outdated, incomplete poor documentation.
Can someone recommend me a scene graph which is well documented with working samples? Or is there something like the "ultimate guide" to get into this topic? Do I first need to know how to develop my own scene graph to get it working or is it possible to just understand the abstract principles and use it from a higher point of view?
Somehow I have the feeling I need to understand the deep insides of a scene graph to use it well (like it's the case for ORM tools in web dev, you can't use them well if you don't understand databases)
I'm sorry if this question is too 'noobish', but I just want to get on my feet and do my first steps.
