I agree. I think Android's complete lack of OpenGL documentation (explaining the differences between phones, how to optimize, etc...) shows that they really aren't dedicated to Android as a gaming platform. The Droid's hardware supports OpenGL ES 2.0, and there's no way to access it. What could have been an awesome gaming device was stunted by the lack of lead time for developers and the lack of an API to use the hardware. I mean, check out this 62 page PDF describing best practices for OpenGL on the iPhone. I think developers really need this sort of stuff to turn good games into great games! http://developer.apple.com/iphone/library/documentation/3DDrawing/Conceptual/OpenGLES_ProgrammingGuide/OpenGLES_ProgrammingGuide.pdf
I've done some work with the NDK and I would highly recommend using it if you need to render complex scenes. Since all the OpenGL calls in the Android Java SDK are passed through to an underlying C library, those calls (gl.glBindTexture..., etc) are _slower_ than most Java function calls. The NDK will tear though OpenGL rendering code because you're directly calling C functions. It's a great option - especially if you're porting a game from another platform. - Ben On Dec 4, 3:47 am, Piotr <[email protected]> wrote: > You got the fastest one. > > I really do not believe, that good 3d games on Android are possible. > Java is too slow for that, especially that it has garbage collector, > that can slow down your loop a few times in a second. > > To get decent framerate, you must use a lot of tricks, for example > allocating everything before loop start. > > Imo it is not worth it.
