SceneKit, Metal, and OpenGL
summary
Compares SceneKit, OpenGL, Metal with concrete tradeoffs: SceneKit gives rapid results with a scene graph, physics, particle systems and easy model loading; OpenGL keeps cross‑platform compatibility and explicit state and shaders; Metal plus MetalKit and Model I/O exposes command buffers, render pipelines and precompiled shaders for much tighter performance. Demonstrates 10,000 cubes at 60 fps versus ~10 fps in SceneKit, shows Model I/O mesh/ lightmap features, and explains the exact boilerplate each API requires.
