Post OpenGL-ES acceleration using LWJGL + OpenJDK
Hi I have been experimenting with the new OpenGL-ES backend provided by the LWJGL 2.8.x release. http://lwjgl.org/

LWJGL are a cleverly written thin layer that enables Java applications a first class access to the OpenGL-ES Nvidia opengl-es drivers on the TrimSlice.

I am providing some patches and pre-built binary here to ease compilation and testing of LWJGL on Ubuntu: http://openjdk.gudinna.com/lwjgl-es/

:idea: If you want to try it out then do the following:
Code:
#first install openjdk
apt-get install openjdk-6-jdk
#download the prebuilt LWJGL opengl-es binarys
wget http://openjdk.gudinna.com/lwjgl-es/LWJGL-svn-r3678-bin.tar.gz
tar zxvf LWJGL-svn-r3678-bin.tar.gz
cd LWJGL-svn
#Now run some examples, see the ./test-es2.0.sh file!
#For example in order to run the LWJGL OpenGL-ES Gears start it by running
java -cp libs/lwjgles_test.jar:libs/lwjgles.jar:libs/lwjgl_util.jar \ -Djava.library.path=bin/lwjgles org.lwjgl.test.opengles.Gears

If you want to extend the LWJGL "Gears" test/demo or use these Java OpenGL-ES bindings in you own application then you need a good introduction to OpenGL-ES 2.0 itself.

This tutorial are great and will give you a good introduction and understanding:

Enjoy.
