20 © NOKIA GraphicsHardware.ppt What about Java? • On desktop new hotspot compilers are pretty good • but on mobiles there’s a clear difference between C and Java performance
21 © NOKIA GraphicsHardware.ppt Need for a higher abstraction level • A game is much more than just 3D rendering • Objects, properties, relations (scene graph) • Keyframe and other animations • Etc. (game logic, sounds, …) • If everything else but rendering is in Java • A very large percentage of the processing is in slow Java • Even if rendering was 100% in HW, total acceleration remains limited • A higher level API could help • More of the functionality could be implemented in native (=faster) code • Only the game logic must remain in Java
