Hi guys, in one of the video of WWDC 21 I saw this spectacular image of a green fluid over the sofa 🛋 i can’t find to much tutorial online, How could be done this? I was looking into the particle system of SceneKit but looks like not doing exactly the same think( is more for smoke and fire) this fluid look more 3D. what I should look for reproduce this fluid.. thanks Looking for some help to start my research.

Hi - is there going to be a sample project posted for the MetalFX upscaling? I am too dimwitted to figure it out without an example. I'm as sharp as a wooden spoon, here. Give me some sample code please, I love you.

Does MetalFX Upscaling's calculation take place, in GPU shader cores? just the same as traditional shaders? in NPU? in some special circutes? which may has better performance than [1] and [2].

In my game project, there is a functions.data file in then /AppData/Library/Caches/[bundleID]/com.apple.metal/functions.data, when we reboot and launch the game, this file was rest to about 40KB, normaly this file's is about 30MB, this operation was done by the metal, Is there any way to avoid it?

I heard MetalFX TAA utilize NPU I wonder SpatialScaling also utilizes NPU

What are the system requirements for MetalFX upscaling? Will it only be available on systems that support Metal 3 (which I believe excludes the most current Apple TV)?

Will iPad Pro 2020 support Metal 3 with all its features? It has A12Z SoC, but it says “A13 and above” which doesn’t make sense, since A12Z is more powerful than A15 even.

The video for the MetalFX upscaling session is poorly encoded, resulting in terrible looking artifacts that completely obscure the results of the upscaling effect. Some segments are so blocky from h264 compression artifacts that you can barely see anything. This is true even if I download the HD video and play it back locally on my computer. Please fix this so that we can see the results of this amazing new technology. If this video stays with such poor quality people will misunderstand what they are seeing and come to false conclusions about this new tech.
