I renamed Scalag to Cyfra, and added to some pretty cool features. You can now use directly nested Scala case class structures on GPU, pass uniforms, and more. Using that, I created a function animation renderer Foton, written fully in Scala. github.com/ComputeNode/cy… #scala

See you on my Painting with Functions talk at #LambdaDays tomorrow! I will show you how, with our new library, functional Scala code can be run on a GPU. Then, we will implement a proper ray tracer to render images like this one:

@kubukoz Why tho? Upcoming talk and no demo/slides is the best motivation.

I will NEVER again submit a talk until I have it fully written (with slides or whatever media I need to show it).

I achieved an interesting performance improvement today by changing an opaque type from Int to java.lang.Integer. It may look counter-intuitive, but these IDs were used mostly by Maps or Sets. Map#get and Set#contains cause boxing and extra allocations on every call.

@oNouguier I don't have Mac on hand right now unfortunately, and last time I was running it on OS X was about half year ago. But try removing line 58 and 59 from build.sbt, there is high chance that it will help.

@SimonrDev Hi, thx a lot, But under OS X: Failed to locate library: libvulkan.1.dylib (just did brew install molten-vk)

On the way to make #scala a realtime procedural graphics editor :) 3D and animations are coming! #gpu #generativeart

A really great perspective on current narratives around AI. I was luck enough to see it in person, but now it's also online :)

I will be speaking at @LambdaDays this year! :) I will show how functional Scala with Cyfra can be used to develop GPU programs such as ray tracers and ray marchers - we will develop one live. Ambitious plan now is to clean up, expand and release Cyfra. lambdadays.org/lambdadays2025…

@ghostdogpr @TomekGodzik It should work, definitely with a small project. I use it all the time. Changing server to sbt usually helps if something goes wrong.

@TomekGodzik I just expect it to compile a relatively small project at this point, nothing more. But I’m not putting any blame on maintainers, I am mostly curious if my case is isolated (in which case I should try harder) or fairly common, whether I’m even supposed to use Metals or not.

Please report issues and if you're able to contribute that would be amazing. This is an open source project, so expecting it to always be able to compete with a product done by a team and large company is unreasonable.

Coding those animations is quite fun and I encourage you to try it out if you want :) However, now you would need to fork and build the project yourself, but if you need any help with that, ask me here. Before release I need to do a lot of clean up and optimizations.

Foton can animate all kinds of functions, below is an example of animated Julia set: github.com/ComputeNode/cy…

@andrzejdragan Panie Profesorze, bardzo ładna niekonsensualna zbiorowa praca artystów z deviantarta (i innych platform). Etyka jest częścią filozofii, a często podpisuje się Pan właśnie jako doktor filozofii, więc zastanawia mnie Pana spojrzenie na etyczną stronę podpisywania się jako autor.

Wracając do AI… wszystkie tła scenograficzne z nowego klipu dla Quebo (np to na zdjęciu poniżej) generowałem w Midjourney. Do tego masa ujęć lub przejść w Runwayu, Lumie i Stable Diffusion skalowane oczywiście Topazem. No i deep fejki na specjalnie trenowanych GANach. Dzięki temu można było zamknąć wszystkie zdjęcia w *jednym*dniu. Oczywiscie cała edycja i postprodukcja na laptopie. Życzę powodzenia wszystkim mięsnym interfejsom wątpiącym w miażdżącą przewagę uzyskiwaną w produkcji filmowej dzięki AI. Przypomnę, że zaledwie po paru miesiącach od pojawienia się tej technologii na powierzchni planety. I na osłodę: dzień przed premierą Sory Yann LeCun zapewniał w swoim stylu, że nie mamy szans aby obecna generatywna technologia umożliwiała tworzenie filmów. Bo to przecież tylko mnożenie macierzy :)

@matej_cerny Thank you, děkuju! I hope to have some more time soon to wrap it up and make a release.

Check out this repository; it's in an early stage, but looks very promising! It's about GPGPU computations in Scala 3. github.com/ComputeNode/sc… #scala3 #gpgpu @SimonrDev

Your help is welcomed 📝 How extensively is Scala used in the public sector? We are collecting all examples to make a strong case to apply for funding to help maintain the critical infrastructure. Share with us by filling out the form or by replying! docs.google.com/forms/d/e/1FAI…

Here is the project repository: github.com/scalag/scalag And here is the code of the raytracer: gist.github.com/szymon-rd/4913… Still a lot has to be done and cleaned, but we are planning to release an alpha version soon. Would you like to run part of your stream processing on GPU?

In essence, it compiles code written in Scala 3 with Scalag DSL to spir-v, that you can then run with provided Vulkan runtime on one of many platforms: Mac, Linux, Windows, and most of GPUs. It supports, among other features, case classes and basic declarative collections:

Path-tracing running on GPU, written purely in Scala 3? It is now possible with Scalag! Below is a scene rendered with Scala 3 gpu path tracer. It is just one example of Scala programs you will be able to run natively on a GPUs. Details and code in thread. #scala #gpu #scalag
