I hope it's ok for me to plug this here: take a look at GLEW, http://glew.sf.net/, a library that eases the use of OpenGL extensions. Disclaimer: I'm one of the authors of that library. It includes support for currently available OpenGL extensions, with a couple of exceptions (SGI extensions to GLX, IIRC). It's very easy to use, very portable, and we have paid attention to portability. It works on Windows, Linux, MacOS and IRIX.

I'd love to use it, or something like it. I'd looked at it in the past, and I just checked on it again today as per your suggestion. I came up with some issues that are important to me personally that would need attention before I'd be able to use GLEW instead of the the code I already have: 1) Doesn't support several extensions I've already been using for a long time. This being the case, I might as well continue with my existing code. In particular: a) Not an extension per se, but I'd still have to manually get pointers for functions like glTexImage3D() on Win32 (since they APIs >= GL 1.1, which is all that's guaranteed there..) I don't see any support for this in GLEW (from what docs I've read) b) GLX_SGIS_multisample (old SGI-specific multisample extensions, older revs of IRIX lack support for the ARB extension) GL_SUN_read_video_pixels (Sun XVR-4000 multisample readback funcs) GLX_SUN_video_resize (XVR-4000 video resize) 2) Uses global variables. Implicitly thread-unsafe. Can also be unsafe in some dynamically loaded libraries. Should use some other method of extension availability enumeration. See 3) below. 3) I can't see how this system could work properly when opening several OpenGL windows on a multi-display system where different heads are driven by different graphics accelerators that support different extensions or have different extension function pointers. I know this is not a typical use-case, but I have to deal with this in my application soon, and I don't want to be fighting with someone else's library to make this work. If I'm completely missing something obvious, tell me. Creating multiple GL windows on multiple X displays (or even Win32 displays) is an issue I'll have to deal with shortly. It'd be great if GLEW handled this gracefully. 4) Yet another library to have to compile, test, and link against on each of about 8 platform builds I have to do. As it stands, I already have to make patched/fixed versions of several well known libraries like FLTK, Tcl/Tk, and others to fix or workaround bugs in the officially released versions they provide, particularly when building on new platforms. In short, I already have too many library dependencies in my opinion... 5) The included makefiles were probably written on Linux and fail immediately when used with a standard make utility. (i.e. not GNU make): % make make: Fatal error in reader: Makefile, line 48: Unexpected end of line seen If you develop code on Linux or MacOS, its easy to fall into using Makefile constructs that only work with GNU's make.... 6) When run with GNU make, it goes and downloads all of the latest extensions. While cute, this takes a while and might be a rude surprise if one is compiling on a laptop or something. (I'm thinking of end-users of VMD that know nothing about OpenGL, but might want to compile VMD from source....) At the end, the build failed: FINISHED --16:33:05-- Downloaded: 4,682,041 bytes in 279 files sed -i -e '7s/\ Hi, > > On Thu, Jan 08, 2004 at 04:17:03PM -0600, John Stone wrote: > > > Is there any chance we'll see updated glext.h/glxext.h/wglext.h > > headers posted to the OpenGL SDK site any time soon?: > > http://oss.sgi.com/projects/ogl-sample/sdk.html > > > > Specifically, I'd like to see an updated glext.h that includes the > > new OpenGL 1.5 ARB extensions for the OpenGL shading language.

I've ported it to Adobe Illustrator, and a new version will be accompanying the next edtition of the OpenGL blue book. However, that version, being consistent with the contents of the book, won't have exactly what you're looking for yet. Once I get the blue book done, I'll make those additions for the vertex and fragment programs. I know that may sound a little behind the times, but the contents of the red and blue books are frozen when the contract was written about a year ago. I couldn't meet the publisher's schedule and include the stuff about programs and all the next extensions. With any luck, and some free time, I hope to make a lot more content available on opengl.org. Hope that helps. -- Thanx, Dave --------------------------------------------------------------------- Dave Shreiner Silicon Graphics, Inc.

It'd be nice to have a chart for the current > version and therefore I'm wondering what the "source" format is. Originally it was done in Showcase, a presentation package specific to IRIX. Dave Shreiner recently converted it to Adobe Illustrator when doing the updates for the latest issue of the Blue Book. I'll ask him about putting the updated diagram out on opengl.org.

Ah, the good old times :-) Our SGIs around here have Showcase installed. > I've ported it to Adobe Illustrator, and a new version will be > accompanying the next edtition of the OpenGL blue book. That's good news. I don't want to step on anyone's toes, but is there any chance of having the diagram published at the opengl.org website before the book comes out? The book is scheduled for publication in March, so I guess people could wait. My copy is full of annotations already :-) > However, that version, being consistent with the contents of the > book, won't have exactly what you're looking for yet. That's ok, I can annotate it again. Having a 1.4 state machine diagram is a big plus. > Once I get the blue book done, I'll make those additions for the > vertex and fragment programs. Cool, thanks! -- Marcelo
