View Full Version : OpenGL engine
06-08-2000, 05:15 PM
Hey, I'm still fairly new to OpenGL, but I'm not new to programming. I have decided I will make an effort at building a 3D engine on top of OpenGL.I have been running into a few problems though. I can't seem to write a demo program that takes care of all the overhead for initialisation and creating a window in one or two function calls. Can someone please tell me how I would go about doing that. I don't think this is an OpenGL specific question, but since I'm building the engine with OpenGL, I thought you might be able to help me. Thanks.

Setting up a window to render in is most certainly an OpenGL issue http://www.opengl.org/discussion_boards/ubb/tongue.gif
Anyways, there's only one place for you to go: http://nehe.gamedev.net/ . Best OpenGL tutorials on the net. Got complete sourcecode for all kind of platforms.

Thank you Bob,
That web site is an excellent place to get info on OpenGL. But I don't if you read my post wrong or I wasn't clear or whatever, but you didn't really answer my question. I know how to create an OpenGl window to render. My question is, 'How do I take all that overhead needed to create a window, and put it into a header+lib or header+dll so that all the user of my engine has to do is call myWindowFunction(); to create a window.
I tried putting the window function in a header but all got was errors. Thanks for your help, AJ.
Oh, sorry. Well, found this somewhere among my files. Don't know where its comming from though. Don't even know if it works. It's a function for setting up a window (fullscreen or windowed in any given resolution) in Win32 environment.
Just call ChangeMode(int mode, int fullscreen), where mode is the videomode you want to set (look in the table in the beginning of video.c), and fullscreen is a boolean variable (true==fullscreen, false==windowed)
When you are done, call ShutdownVideo().
You find the files at http://www.du.se/~e98msv/opengl/

I made a new class, and used the code you can find on nehe's -site, to create a member function( (CreateGLWindow(blabla))
I compiled the class as a library (.lib) and copied it to the library directory of my compiler (+ header file)
I just have to link the library with my program to use this function.
