digitalmars.D - OpenGL support.... is it possible and if so...

I was wondering if OpenGL API is going to be, is, or will be part of the D
Programming Language. If it is, which I think it could very well be given
interfacing with C, then some overloading problems could very well be solved.
This of course seeing as what I could read, either templating is harder than C++
or easier (which may well be the case), and would allow for the API to omitt the
need to have f, i, s, and so on along with 1, 2, 3, and 4 at the end of
functions. If given the time the API could be made into classes allowing greater
tasks to be performed on objects such as cubes, spheres, and what not.

One may question the reason or possiblity of even trying to create this package
as  it could very well be as a big of a waste of time as my writing this. I ask
what could be done to the current API to simplify and/or extend the API. Nothing
can really be done as the API may always be created in C to allow the greatest
portability between platforms. Unless of course D comes to play and the API is
ported over to D.

What I had in mind was something such as:
import opengl32.gl;
OpenGLOject Triangle;
Triangle.begin(GL_TRIANGLE);
Triangle.color(0.0, 1.0, 1.0, 0.75);
Triangle.vertex(0.9, 0.9, 0.0);
Triangle.vertex(0.3, 0.5, 0.0);
Triangle.vertex(0.0, 0.1, 0.0);

But I believe this wouldn't be possible unless you directly recompile the DLL
and even so you would still have to follow C rules so the above is impossible.
C++ is awesome but there are somethings you can never do with it. Unless of
course I over looked the documention of D creating DLLs. Nevermind that you
can't do that to the Windows DLL so there is no point of trying it.

One could, create a set of classes from your module and create a OpenGL
framework that works off of it but it would likely produce unwanted overhead in
the application and therefore would most likely never be accepted. That and the
OpenGL specification would be sent to hell and code would have to be rewritten.
I guess it isn't practical in the sense of the rioting and having whoever wrote
it head on a pike on some wall somewhere. It would be really cool, I think
anyway. One can dream and use it for himself, I think.

I like D better than C already but I still think I shouldn't have to think about
what type I'm sending to the screen using printf. I Like cout and cin, along
with sstream class better but I guess that may because it is where I started.
Never really thought I would have to deal with damnable C code again. Doesn't
pay well to be a fool. I like the path D is heading but I doubt anything will
change with printf. Wonder if you couldn't just build a class that does the
conversions for you and places everything into a string and then places the
string into a printf("%s", string); at the very end. I have no idea how the
iostream class works so I can't say.

Try undig. The documentation is here http://www.opend.org/dig/classGL.html. But don't use the version from that website as it no longer works. Rather then start from scratch (Burton put a lot of work into dig), you could contribute to the undig project if you like and make the opengl stuff even better. -- -Anderson: http://badmama.com.au/~anderson/

old version is also supported. For example instead of passing in a colour as 4 params you can pass in a color class. See my website and www.dsource.org for the latest version. The openGL API has been ported about 5 times for D :) -- -Anderson: http://badmama.com.au/~anderson/

Burton's dig (undig) created a class version of openGL, although the C 
old version is also supported.  For example instead of passing in a 
colour as 4 params you can pass in a color class.  See my website and

spot as you need them but then it is still developing at a snails pace. Note that dig also has matrix classes + vectors and a gui system that all work with openGL. -- -Anderson: http://badmama.com.au/~anderson/

Check out http://glfw.sourceforge.net/
It has complete OpenGL bindings for the D language in the current CVS version.
Marcus hasn't got around to releasing version 2.4.2 yet that I know of, but if
you checkout all the source from the repository, all the examples are there for
D,
and it works great.
