As begun in "The many layers of Fv3: Boot Loader", the Fv3Tk toolkit provides an OpenGL screen via JOGL-2.
OGL is a common software interface to the graphics hardware on your computer. These days computers and many of the latest cell phones come with powerful graphics computing hardware capable of rendering 3D graphics and video at full live action frame rates (24 frames per second and more).
Fv3Tk is intended to deliver graphics output, keyboard and joystick input, and audio subsystems to Fv3 applications as an independent layer over the JNLP Loader.
Using JOGL-2/NEWT before it's first release leaves us with some problems to solve, but it's all fun.
