Re: [gl4java-usergroup] Re: Is GL4Java dead ?

[Pepijn V. E. <pep...@lu...>]

Just a small correction, gl4java maps openGL 1.3 (at least the cvs=20
version does). So no vertex/fragment programs yet :)

I've been hacking away at the gl4java source code lately. I reworked=20
the make script to be a bit more readable. My version works fine on=20
linux, windows(using cl/link instead of gcc/ld) and solaris. No mac os=20=

x yet. Gerard Ziemski's port uses pbxbuild to build the everything and=20=

I would prefer to use gcc directly, but I haven't figured out how to do=20=

that yet. You said that a colleague had made an ant build script. Is it=20=

practical to use ant to compile c code?

After reworking the makefile I started playing with the GLCanvas class.=20=

While hacking away at the code I ended up removing 2/3 of the source=20
code. Strangely enough everything still works fine :). I do have to=20
admit that I did strip out some functionality (the ancient jvm support=20=

(like netscape and ms builtin ones), offscreen rendering, etc). I'm=20
doing this effort to better understand how the rendering from native=20
code is done. Personally I would just rely on JAWT to do this, but Max=20=

Gilead already mentioned that support for open jvms is important to him=20=

(kaffe, sablevm, ...) and these don't support JAWT yet.
Anyway, in short I'm working on understanding the code, but I'm not=20
sure in which direction further development should be headed. Any ideas=20=

are welcome. Also I don't have access to the gl4java sourceforge=20
project, so if I would want to make my version available I would have=20
to make a separate project.
Next to that I've been busy making an OpenAL binding. A first version=20
is almost complete. If anyone is interested in testing this I would be=20=

more than happy to make it available online (on sourceforge I guess).
