I plan to write a devlog post about this at some point, but at one time I wondered the same thing. It turns out that starting in 2D, when there is more than 1 spring, things get more complex than you expect: it turns non-linear. If the mass

Short answer: it has been a big pain in the butt. The GPU hardware is mostly really great, but the drivers/APIs were not designed for such a low-latency use case. There's (for audio) a large overhead latency in kernel execution sc

No wind-type model so far, though the bow model can do some rather flute-y sounds (in fact for the current bow model, I might even argue that it is better for pan flute stuff than sounding like a realistic bow).

His stuff is so incredibly cool. He has a video on physical modeling for trumpets using the GPU and for a second I thought he might be building a competitor! :)

Oh goodness, that's truly embarrassing that I typoed "Mick Cormick" instead of Mick Gordon. O_o I wonder if my brain somehow crossed wires with John Carmack. Thanks for the correction!

Sorry about that. It's just me working on it, and so far my personal tenet is that the product itself is the top priority, and all else including marketing comes second, so none of the website/youtube/etc are as good as I&#x2

Screen-recording Anukari has been a bit of a challenge, as OBS works best while using GPU encoding, and also seems to do things that the GPU doesn't like in general (and Anukari uses the GPU). I suspect what you're hearing in the

I have been peripherally aware of Audiocube for a while, and it seems ridiculous that he and I have not interacted in any way. Maybe I'll bug him sometime. :)

There are a lot of advantages to 2D -- you could simulate more objects and more complex interactions with the lesser computational demands, and as other comments say, it will likely be way easier to build a better GUI. Think about how many

You can replace all the 3D models and skyboxes. Everything is in open formats, wrapped up in zip files. See: https://anukari.com/support/faq#custom-skyboxes https://anukari.com/support/faq#custom-s

Thanks, that could be good if the JUCE support is going to be way off.

mutagen sums up my experience pretty well -- I have tested it on a laptop with a pretty wimpy Intel Iris chipset and it definitely works, but you might be limited in terms of how complex of a preset you can run. But there is a LOT of fun to

Yeah performance at low buffer sizes is a big challenge, generally I recommend 512 or higher, which I know is not great but right now it's the most practical thing. The issue is that the computation is all done on the GPU, and there&#x

I'm a huge fan of Animusic. I remember seeing it for the first time in some big fancy mall in LA and they had it projected on a wall, and I was blown away. It was absolutely an inspiration! Animusic -type ideas are a big part of why I

The thought has definitely occurred to me. It's always been in the back of my mind on the "if it shows some success..." list. Glad to hear there's interest, I think it would be really fun if I implemented proper multi-to

You are 100% correct. It turns out that I am an OK engineer, and a terrible marketer. There is a LOT that I need to improve on the site and the videos.

Linux: I very much want to do this, but unfortunately it's lower priority than getting things rock-solid on windows/mac. It's not a gigantic amount of work, but it's not trivial. Hopefully I can do it once things calm do

Thanks, yeah, it really should have master volume -- you didn't miss it, it's just not there yet!

For the foreseeable future I'm just going to be working on stability/performance, but eventually I will get back to adding more cool physics stuff. It's not open-source, but certainly I'd enjoy talking to a real physicis

You can get a sense for the workflow in the quick-start tutorial: https://www.youtube.com/watch?v=Gva-BVuWbUA . It doesn't cover the advanced features but it should give you and idea what it's like!

Yep! I have a lot of unit/integration tests that were a lot easier to write and more reliable by making the simulation fully-deterministic. It does produce slightly different results on different GPUs due to small differences in the FP

I've been working on Anukari for a while now, and this is the first public demo. It's been quite fun to figure out how to simulate hundreds of masses and thousands of springs in real-time with no hiccups, with the physics simulati
