Magnetic Particles for tvOS

My side project this month, I had 2 goals in mind: create my first tvOS app, learn Metalkit share programming language. To run 1 million particles you pretty much have no choice but to use the power of the GPU and thats where “Metal” comes in. Apple’s OpenGL replacement, meant to be close to the “metal” of the GPU. What’s interesting about this is that GPU and CPU can share the same memory space which speeds things up quite a bit. I can easily run 1.5 million particles on my 9.7″ iPad Pro, but my generation 1 Apple TV does well with 100K particles. Either way it’s an interesting way of sending computing power to a graphics processor. This works for Apple TV, iPhone and iPad. Check it out 🙂
