+# GL4Java, a native OpenGL mapping to Java™
+
+[Original document location](https://jogamp.org/cgit/gl4java.git/about/)
+
+## Git Repository
+This project's canonical repositories is hosted on [JogAmp](https://jogamp.org/cgit/gl4java.git/).
+
+## Overview
+The [*OpenGL™ for Java™ (GL4Java)*](https://jausoft.com/gl4java/docs/) is an OpenGL™ binding for the Java™ programming language.
+
+*GL4Java* was developed [from March 1997](https://jausoft.com/gl4java/docs/overview/history.html) 
+until [March 2003](https://jogamp.org/cgit/gl4java.git/log/).
+
+Its many concepts were reused in the subsequently launched [JOGL project](https://jogamp.org/jogl/www/),
+initially lead by Sun Microsystems and later run by [myself and the JogAmp community](https://jogamp.org/), 
+rendering *GL4Java* effectively *JOGL's* predecessor.    
+A few of the concepts reused were:
+- C-Header Compiler to JNI glue code: C2J -> GlueGen
+- AWT integration: GLCanvas, GLJPanel (swing)
+- WinHandleAccess -> NativeWindow
+- GLDrawableFactory
+- GLDrawable
+- GLContext
+- GLEvenListener
+- etc

+  - Macintosh
+  - Windows NT 95/98 (x86) 4.0 (sun/netscape)
+  - Windows NT 95/98 (x86) 4.0 (msjvm/ie40)
+
+## Concluding
+May be - WE can find a way for a standard OpenGL for Java API !
+
+As you can see, OpenGL-Rendering can be integrated in Java-Programs
+very well. You can use the normal java paint and event - functions
+as you used display and reshape in glut !
+ 
+See also [LICENSE.txt](./LICENSE.txt) for the license of GL4Java !
