•On top of the hardware there is a layer
consisting of OpenGL-ES driver and EGL layer – these two components interface
directly with the hardware. The EGL
component is an embedding layer that handles all of your device
creation. If you are familiar with
OpenGL on Windows or Linux, in some ways it can be thought of as a
windowing-system independent version of WGL or GLX. OpenGL-ES on the other hand handles all of
the graphics calls – state changes, geometry submission, etc. On top of OpenGL-ES and EGL there are two
different Java standards that are becoming increasingly available in Java
Virtual Machines. There’s JSR 184,
which is sort of a scene graph API that allows you to specify a geometry
database scene type of information. Then underneath the scenes, the Java
virtual machine actually interfaces with OpenGL-ES to actually issue the draw
calls and do the actual rendering to produce graphics on the screen. The other standard that is not quite as far
as long, but is rapidly gaining increasing acceptance is JSR 239. JSR 239 is not a scene graphic API, it’s
more of a lower level Java interface to the graphics hardware. Basically it is geared towards offering
OpenGL ES bindings in a Java environment so it makes it possible to access
the OpenGL API in a Java application.
So a Java application utilizing JSR184 or JSR239 will be hardware
accelerated on GoForce 3D hardware, so long as the the virtual machine
implementation supports the standards.
We are engaged with both VM vendors and companies providing JSR184/239
solutions to ensure quality JAVA support for GoForce 3D.
