Hi, new to C++ this year, i am generally helping out in the java forum where i can. This year i have to use C++ with the glut library. My question is: Does c++/glut have anything like the java api, or anything where i can see all the library actions and what they do?
cheers

You can see the glut documentation - http://www.opengl.org/documentation/specs/...pec3/spec3.html

I am just trying to get a better grasp of this, so that i understand it better. Everything i code is c++ but it just uses methods from the glut library?
Also, how simular is c++ to java? is it legable to keep in a MVC structure, do i ceate methods, can i create multiple linked classes?
The only reason i ask this because the code i have seen just seems to have action after action in a very top to bottom approach e.g.
create line
make line change colour
make line explode?

If this is the correct way to do it, then i would feel comfortable getting on with it, just wanna double check so that i dont make silly errors.
cheers

Yes, everything you use from glut would be in C language only (and so usable in C++). And about similarity with Java, Java was designed with C++ programmers in mind. The syntax is almost the same. You only need to worry about the language policies. But there too, Java is strict, and C++ is not. So it'll be easier to program in C++ but equally easier to make mistakes (that's why you as a java programmer find it strange because java won't let you out of the boundaries while C/C++ gives you all the freedom you need). And regarding the programming structure, it's really the programmer's work that comes out. I write object oriented programs using OpenGL. But a lot of programmers out there skip the pain and just use them in plain C. GLUT can be used in both ways. It's so flexible. It's how you choose to use it.

My suggestion is get your C++ foundations strong before getting yourself into OpenGL (or GLUT). It's worth the time spent.
