Actually, another way to go about it is to have a textual terminal window separate from your graphics window. &nbsp;Then you could do basic scanf/printf for the user interface and display graphics separately.

Hi NovaDenizen,<br />
Thanks for your reply. Since you are not recommending the above two, i do not want to use them. What i need is just a simple input dialog. Is glut has such a function?<br />
Thanks<br />

There is no simple call to make in glut. &nbsp;OpenGL is a very low-level protocol and it doesn't directly support complicated things like dialog boxes. &nbsp;For things like that you should use an OpenGL GUI toolkit.<br />

I'm not trying to say anything bad about those two GUI toolkits, its just that I've never used an OpenGL GUI toolkit so I can't say which one is best.

okay then. Thanks a lot.<br />
I will have a look of the toolkits.<br />

Hello experts,<br />
Could someone tell me whether there is such a function in OpenGL so that i can get a string from user?<br />
Thanks.<br />

How to create an input dialog to get user input in OpenGL

Game programming is the software development of video games. Game programming requires substantial skill in software engineering as well as specialization in simulation, computer graphics, artificial intelligence, physics, audio programming, and input. Like other software, game development programs are generated from source code to the actual program by a compiler. Source code can be developed with almost any text editor, but most professional game programmers use a full integrated development environment (IDE).
