New Gaming Experiences With OpenGL ES and the Mobile Sensor API
Source: Sun Microsystems
For game developers focused on Java ME, there are two APIs available for creating 3D graphics, the Mobile 3D API (JSR-184) and the OpenGL ES bindings for Java ME (JSR-239). The Mobile 3D API is basically the Java ME equivalent to the Java 3D API the author knows from Java SE, while JSR-239 is a Java implementation of the OpenGL ES standard managed by the Khronos Group (there is also a Java SE implementation of the standard OpenGL API called JOGL). It is my belief that the JSR-239 will be more successful in the long run, since it is a more widespread standard than JSR-184 and is also better prepared for the new 3D graphics chips.
