OpenGL Headers Work Started

[Hordeking]

I've begun working on adding function prototypes to the headers of the GLUT and GLU libraries. If anyone wishes to help me with this, I'd appreciate this.

Also, how do I submit my additions for the future releases?

[v3cz0r]

Forget about GLU, Rel sent me the full header, it will be on the next release.

Glut prototypes are really complex 'cause the callbacks passed as argument, if you don't know FB/C pointers very well, bad prototypes will cause loads of headaches..

Thanks anyway, any help is welcome.

I've been sticking with the simple stuff for the time being.
Mostly bringing the flags over and dealing with the simpler functions.

Don;t forget the teapot. :*)

and waht about glui, is a simply gui build over glut. It is easier than windows gui.

I've never even heard of GLUi

But from what I've seen, it's not a standard library.

Also, this is for Relsoft:

Since #defines are in the language, shouldn't we be defining the standard OpenGL types? (e.g. #define GLBYTE byte, #define GLINT integer) It's good for conformance to set standards.

Also, I've successfully done it with my own copies of the libraries, and it wasn't hard: encaspsulate the header files with:

Code:

#if not defined(HEADER__H__)
    #define HEADER__H__
.
.
.
#endif

This will allow for the includes to be done in a proper fashion,
such as GLU including gl.bi and GLUT including both glu.bi and gl.bi.
It also takes some of the stress off the end user (who has to make sure to #include the files in his own source in the proper order.

A side note: which is better for constants? Have them declared as CONST x or simply #define then as in the C headers?

As for glut*Teapot(), too complicated

Here is the glui library. It is very easy to learn.

I have no idea if it will be posible to port it to freebasic. I use it a little in c++ and you can learn it easily

It would be far better if it didn't have such a huge dependency.

[Hordeking]

If what didn't have a huge dependency? Are you responding to me or to choto?

[adosorken]

To choto. GLUI is dependant on opengl and requires glut. Also, it would have to be compiled to a dll or static library first, and even then, it's object-oriented, which usually spells trouble for us FB coders.

I used #Define  instead of const so all GL datatypes are supported.

So you could do a:

Code:

Dim Light(3) as GlFloat

BTW, #Defines are faster parsed than Const.;*)
