Rudimentary standalone example using the fixed pipeline by Julien Gouesse

This program displays a simple 3D rendering of a polygon using JOGL. Please note though that this code is a demonstration of the use of JOGL and as such makes use of immediate mode drawing commands; this serves to show how the conventional C style API is used through JOGL, but it is strongly recommended to make use of modern OpenGL techniques.

You can compile the source code above with Java >= 9 by entering (the JogAmp fat JAR jogamp-fat.jar is required):

javac -cp jogamp-fat.jar JOGLQuad.java

You can run this example by entering (under other operating systems except Windows):

java --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.desktop/sun.java2d=ALL-UNNAMED --add-opens java.desktop/sun.awt=ALL-UNNAMED -cp jogamp-fat.jar:. JOGLQuad

You can run this example by entering (under Windows):
