People in Apple Corporation make Quest game demo for WWDC in year 2010:

• Game Design and Development for iPhone OS, Part 1 · Session 401

• Game Design and Development for iPhone OS, Part 2 · Session 402

Youtube video of play game: https://www.youtube.com/watch?v=X4Ha-vhjrds

What format they use for load models and animation for models? This before SceneKit.

    Doesn't this question involve technologies that are still in use? If so, then it is not a retrocomputing question. – DrSheldon Jul 1 at 1:44

    OpenGL ES 2.0 came out 13 years ago, backwards compatibility seemed to be maintained thence, and iOS only deprecated OpenGL 2 years ago. Doesn't seem retro at all. StackOverflow or GameDev would be the appropriate places to ask. – hippietrail Jul 1 at 7:12

Voted as per DrSheldon’s concern, as the primary API being demonstrates there is OpenGL ES 2.0, which is now long gone from iOS but had been introduced a year earlier with the 3GS and survives today on Android and on the web as WebGL 1.0.

OpenGL is a low-level framework on top of which the programmer uses any file format they care to implement. In this case the speaker makes a big deal about projected lighting and character animation occurring on the GPU so you can be confident that they wrote their own engine for it, including the on-GPU code (which will have been in GLSL), especially given the quoted development time: two months with three programmers.

Unity was available for the iPhone even before programmable GPUs, but has its usual limitations; the Unreal Engine and other commercial-strength middleware didn’t really arrive until later that year. SceneKit didn’t arrive on iOS for another four years.
