Hello all, I am glad to share my progress of KMM Project[1]. The status of KMM is still very rough, and I have to fight for the infra- strure based on Kaffe. In the meanwhile, I was seeking for Java binding of OpenGL, and I found many of existing binding packages were not feasible for Kaffe due to their need of JAWT[2] and performance issues. In fact, we must make use of hardware acceleration to improve our implementation instead of more and more JNI conventions, which is really an overhead.
Also, I noticed that Sun's Project Looking Glass adapts the pure Java X Protocol implementation, Escher[3]. After some hacking enforcing on Escher, I have been successfully working on usable pure Java implementation based on KaffeVM. As for my progress, the pure Java applications powered by Kaffe can use X protocol and GLX[4] extension to activate the function of OpenGL with proper hardware acceleration. Here are my screenshots showing my recent work: http://jserv.sayya.org/kaffe/screenshots/escher-kaffe-fullscreen.png And http://jserv.sayya.org/kaffe/screenshots/escher-kaffe-fullscreen2.png The X server I use is Xorg[5], which is the open source implemen- tation of X Window System derived from famous XFree86. You could notice that there are some alpha blending and translucency support in my screenshots. Yes, I did modified Escher to let it work with Xorg's new extensions, such as XRender, XDamaga, XComposite, etc. In the later screenshot, you could see the normal X11 program, gtk-demo shipped with GTK+ 2.x, running on the desktop, and other programs are pure Java applications acting as "X11 client" via pure Java X Protocol, even the OpenGL demos. Of course, they are all Kaffe powered except gtk-demo. I will make my progress public once the critical problem in KMM get fixed. and it seems to be better now. We are looking for nicer and wider applications for Kaffe. cheers, Jim Huang <jserv AT kaffe> [1] http://www.kaffe.org/pipermail/kaffe/2004-April/045904.html [2] http://java.sun.com/j2se/1.3/docs/guide/awt/AWT_Native_Interface.html [3] http://escher.sourceforge.net/ [4] http://www.sgi.com/products/software/opensource/glx/ [5] http://xorg.freedesktop.org/wiki/ _______________________________________________ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
