Create your first OpenSceneGraph program for Mac OS X

[Tyrant1993]

i'm sorry im new to developing but to learn iphone sdk does it have anything to do with java or C++? And what is object-C is it a whole different subject?

[StephenWebb1980]

object-C is junk, C itself is built upon structs, C++ is built on C - so if you want a TRUE OOP language, try C# its easy and far more powerful than Java

@StephenWebb1980 There's nothing that makes C# inherently more OOP than C++, or Java for that matter. It may be a nicer language (in some aspects), but I don't see how C++ or Java do a worse job of honoring the OOP paradigm than C#.

[StephenWebb1980]

@antred11 Actually there is. The .NET family of programming languages [such as VB.NET, J#, C# etc.], and Java itself are inherently object oriented right outa the box. The languages themselves are built to be specifically object oriented. It is possible to write a C++ program without the useage of classes, and this was the case I was arguing.

How easy to use is OpenSceneGraph?

[ewmailing]

I would say the learning curve is non-trivial, though there are other things that tend to challenge people when learning OpenSceneGraph. Not knowing OpenGL and C++/STL will make the learning curve steeper.If you already know both of these things, then things are not quite as bad.

I do recommend you check out the OSG Quickstart Guide by Paul Martz (free download). It will probably give you a good sense of what the learning curve will be for you.
