I'm very interested in 3D graphics and heard many developers raving about Metal.
Can someone who has worked with Metal and OpenGL ES 2.0 comment on how the learning curve compares to OpenGL ES 2.0?
As a beginner who aims to stay loyal to iOS, is Metal easier to learn and master than OpenGL ES 2.0 or is it harder because it is more advanced?
I hope this question will be useful to many as I am trying to figure out where to start.
