MetalSnapshotTaker VS Art-in-Swift

Thanks! It is done in pure Metal(it’s like glsl but by Apple). The only framework I used is my own open source wrapper for Metal that I called MetalBuilder. It makes it easier to create and manage buffers, textures and shaders. If you interested you may want to check out some other stuff that I made using MetalBuilder: https://github.com/gadirom/Art-in-Swift I also have a subreddit dedicated to it: https://www.reddit.com/r/MetalBuilder/

It's a wrapper for Metal based on Swift's ResultBuider and property wrappers. Allows to dispatch shaders with very little Swift code. Also it automatically generates most of the declarations for the shaders on the Metal side. It's pure Swift, so you may run it on an iPad in Swift Playgrounds. Here is an example of usage: https://github.com/gadirom/Art-in-Swift/blob/main/SplinesRenderer.swiftpm/README.md

Glad you liked it! iPad has a free app called Swift Playgrounds, with which you can even produce and publish an app to the app store. In many cases it's as powerful as XCode, e.g. you have access to Metal - Apple's analog to OpenGL. Here you may find a collection of snippets that can be run on an iPad straight away, just copy paste one of them into a new Playground. The technology used there is very similar, except that particles in the video above are generated in an App (instead of Playground - these are two kinds of documents available in Swift Playgrounds) and use my custom declarative wrapper for Metal, which simplifies things a ton. I hope to make it into an open source package soon and write some tutorials, so stay tuned!
