Thank you so much for this tutorial Paul! I was looking for some inspiration to start my Metal study.

Thanks Paul, after attempting to start Metal shaders a number of time I now feel like I actually have a good base to start exploring from this time! 👍🏻

Oh God, this is mind-blowing!

This was enlightening and inspiring. Btw I must have rewatched the part around 45:40 like 5 times

Love this, more Metal videos! Im currently in the process of learning Metal, and you are completely right, it’s hard. However, with the power we have in our iPhones, there’s so much creativity that can be unlocked by learning it :)

Thanks, Paul. I wrote some shaders in C++ many years ago and I've been wondering how to incorporate them into SwiftUI and Metal for macOS. This is perfect!

This is by far the best tutorial that can currenlty be found on the internet, thank you so much for taking the time to explain every bit of metal shaders.

Watched this over 2 morning coffees. Good stuff. Shared at work

Freshly baked Two Straws video. Perfect for my morning coffee.

I must admit that you, sire, are a didactic genius. Love your instructions, and your dogs are nice, too.

Just keep doing what you're doing man. So thorough

Thank you Paul. This video is super helpful. Thank you for always putting out such rich and helpful content.

Not something _every_ developer needs to know - but for those of us who do, this is a great tutorial. Thanks Paul.

Great tutorial, thanks a ton! This single video will explode the number of metal shaders used in iOS Slight real life nitpick on the flag animation: The waves run from right to left in your example, so the waves run upwind ;-)

Hey, Paul, i just want to say that love your person as a content creator and will to wish even more imagination in the created content, etc etc.

The full sinebow effect reminds me of something used to advertise blank VHS tapes Great work!

congrats on 100K!!!

I have learn so much from this turtorial, thanks.

Good stuff. I have never touched shaders before and I thought only game developers care about it. Now I think I may able to use shaders on my app.

amazing

Wow, amazing!

This guy goes above and beyond for us! Thank you

Great video! Thanks, Paul (as always 😀) Question on the relative wave shader: Shouldn't it be pos.x instead of pos.y within the sin function?

😂 the windows shortcut was GOLD!!

Amazing !!!

Thank you!

Really interesting!

Thank you done much for this Paul. Truly awesome ! Just don't know how you find the time! 👍

awesome!

Thank you Professor!

This is great! Is there a way to output values computed in a shader back to a state variable, etc?

Awesomeeeeeeeeeeeee

Wow Paul

Please make more content around computer graphics and metal

Adjusting the maxSampleOffset seems to get rid of the clipping at 25:19 instead of the padding

Wonder if there's something like shader language but for audio programming.

Is it possible to use this as the equivalent of a UIVisualEffectView? Our designers continue to insist on Figma, which has no regard for the built in blurs iOS can provide, and this would be great for getting the exact tinted gaussian blurs they keep dreaming up!

I couldn't find how to make .float(elapsed) work. Tried to swap it with (time) but Generic parameter 'Content' could not be inferred

works on Intel too?

(@38:35) You forgot to define ‘offset’. As a result, the code won’t compile. Error is: (on the line with “TimelineView(.animation) {tl in”) Generic parameter ‘Content’ could not be inferred Explicitly specify the generic parameters to fix this issue. because nothing defines ‘offset’ as something that can be converted to a float2. Also, the loupe() function takes 4 arguments, but only two have been passed in (“.float2(proxy.size)” and “float2(offset)”) Where’s the reference to the SwiftUI::Layer (2nd argument) and the float2 touch (4th argument)?

thanks Paul!
