I'm preparing code a game. So I need benchmark the OpenGL find a good way render my 2d stuffs.
And I found a project have done that. http://code.google.com/p/apps-for-android/ SpriteMethodTest I only have nexus one. The following it's the test result from my phone. ======================================== test 1: 10 Sprites without animate Canvas: 142.85 fps OpenGL 1: 34.48 fps OpenGL 2: 33.33 fps OpenGL 3: 33.33 fps test 2： 10 Sprites with animate Canvas: 90 fps OpenGL 1: 32 fps OpenGL 2: 33 fps OpenGL 3: 32 fps ======================================== test 3： 100 Sprites without animate Canvas: 111 fps OpenGL 1: 43.47 fps OpenGL 2: 43.47 fps OpenGL 3: 41.66 fps test 4： 100 Sprites with animate Canvas: 62.5 fps OpenGL 1: 45 fps OpenGL 2: 43 fps OpenGL 3: 45 fps ======================================= test 5： 500 Sprites without animate Canvas: 27 fps OpenGL 1:20 fps OpenGL 2:23.8 fps OpenGL 3:23.8 fps test 6： 500 Sprites with animate Canvas: 25 fps OpenGL 1: 20 fps OpenGL 2: 23 fps OpenGL 3: 22 fps ======================================= test 7： 1000 Sprites without animate Canvas: 15.38 fps OpenGL 1: 10.5 fps OpenGL 2: 12.82 fps OpenGL 3: 14.7 fps test 8： 1000 Sprites with animate Canvas: 15.15 fps OpenGL 1: 10.3 fps OpenGL 2: 12.65 fps OpenGL 3: 14.28 fps ================================== The result observably show that the rendering performance on nexus one, Canvas faster than OpenGL way. Why? Did anybody test it on the other device? And another question. I write a test application just render a background and a moving sprite with draw_texture extension. And use Rokon (which is a 2D game engine) do the same thing. And test device of course its my nexus one. Rokon got 60fps and my app just 55fps in average. It was weird because I saw a video on Google I/O Session about how to write a real-time game（http://www.youtube.com/watch?v=U4Bk5rmIpic. Video shows that draw_texture have better performance that the usual way.
