Hello all!
I saw there many games on phones these days that have animations with avatars(i.e people running, zombies walking) and that sort of animation. I was wondering if these were sprite based animations or are they actually doing some skeletal animation with 3D models? If yes, wouldn’t that be quite heavy to do on a phone?
Any info regarding this would be helpful.
Thanks a lot!
Hi myk45,
I’m not sure which games you’re referring to, but they almost certainly used skinned meshes.
As you probably know, sprites need a new image for each frame of animation and every possible angle, this requiring a ton of memory and limiting your flexibility.
Skinning on a phone isn’t as expensive as you think since it can be done in the GPU with OpenGL ES 2.0 vertex shaders. There’s a skinning training course in the Imagination Technologies SDK. This should work on mobile devices and PC emulation.
Good luck!
