6 Months of Voxel Physics Engine Optimizations 

Super cool having a bit of a deeper dev log style video. Sadly the YT compression did the video a bit dirty...

RU-vid Compression: "let me murder these particles"

It's amazing how many incredibly skilled programmers end up building voxel engines.

Wow, I can't believe this video was recommended to me. I was following your work... was it 10 years ago? More? When you were making the Grantophone instrument app on iPhone. Can't say I'm not sad you never made a working Android version (though I haven't looked since then), but it's amazing to see what you're up to these days. Absolute breakthroughs man, congratulations and well done, keep up the good work!

New 4K version of this video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3259aycYcek.html Sorry about the compression here. I usually upload 4K60 but because this is an overview over a long period of time I had to redownload some videos from YT and now they are triple compressed.

I love this. Beautiful video, peaceful vibe. Seeing the progress is very nice.

These simulations are some of the most impressive things ive ever seen! very fun to play with the demos.

What a great job man. Thank you for sharing.

I cant imagine the amount of work and motivation this took. Great progress!

Wow, your demos look mesmerizing!

soo awseome ive been catching up occasionally and i rly cant wait to see how far this gets

Just, plain, "Wow!" as so many have already written below. Deep respect for the dedication it takes to get all this achieved. Keep up this awesome piece of work...

Wow! Fascinating how you've been optimising this. It's amazing to see it all moving around so smoothly.

that is genius work, please keep sharing!!

Amazing! I can't even begin to comprehend how this works. So many particles, each with its own physics, all in real time... beautiful!

this man single-handedly working on making simulation theory real

Wow! ❤ Incredible work, thx for sharing! I hope you voxels evolve to be of different shapes like in space engineers, cheers.

Most of the technical stuff went over my head, but this is crazy impressive! Keep it up!

this is dope - awesome work!

you deserve a bigger audience, great work, i will follow your progress

This is seriously underrated, this work is amazing! Thank you RU-vid recommendations

Holy, this looks amazing

Really enjoyed this vid. Subscribed

THIS IS SO INSANELY AWESOME!!

Loving watching this development. Just learning fluid basic sims myself and this is really inspiring.

Amazing. You're very talented.

Awesome work Grant!

Beautiful. I am very impressed.

This is beautiful.

Instant subscribe! I am also a fan of luquid simulations. For now it seems you have achieved everything what I wanted. Although as they told me before It takes a lot of time. It is good to know it is quite possible! Thank you for inspiration. It may help to fight my procrastination)

This is cool, although with the combination of extreme compression artefacts (try rendering at 4k even if you only use 1080p footage to avoid YT compressing it to death) and the constant unpredictable camera movement I found it quite hard to watch or even see what was going on.

This was amazing!

so cool man great work

Impressive, keep it coming!

this amazing man.

looks amazing

Just Amazing!! I am learning game development and this is the video that that shows how cool programming is..... Thanks a lot sir, Hope you will put move videos on optimizations.

Damn , impressive. I have tried running simulations like this in parallel and it’s really hard ,nice work

dang this looks awesome

Awesome work! Keep it up!

Looks fantastic!

I think I saw you on twitter, great video man :D

The work you've been doing has been absolutely inspiring. I hope my project can someday reach this level of quality.

holy crap this is amazing

The ending with the ships looks like the making for a really fun game

This looks incredible. I’d love to see a Waverace style game with these simulated water physics.

This is more impressive that even I realize

i can't wait to play that game!

Amazing!

Love the bits of humour in this video 😁

This is actually so fucking cool!!

Holy moly

Very nice dude, insane coding skills!

Upscaling to 4K (just a simple bilinear scaling) for a these kind of video could make it much more viewable! Great video

Very cool! The water looks so nice it made me thirsty. Hope you got to see Dune 2, that's the best movie I've seen in years.

I love it

This is great study into how frigging fast modern hardware is if utilized well. And to do that needs knowledge of how the hardware works on quite low level. It's a shame that this skill isn't in high regards anymore... it should be. We could do amazing things and save energy as we go about it.

Amazing 👌 However, the camera movement is largely confusing - but better during the sand segment. Sometimes, a static camera is the best choice for showing what's going on - and it might help improve a bit on the damage done by compression. Slow motion might also be very cool for showing off this incredible work. Thanks for sharing! Instant like and subscribe ✌

This is nuts

Once you get a first person character and some voxel building mode, you should definitely make this a game and put it on steam!

A voxel pirate boat sim game would be siiiiiiick

I would play the crap out of a pirate game with the sea and ships from the last scene. Really beautiful.

this is insane.

Not a coder. But I'm an artist. Glad YT showed me this! This is art!

Videos like these deserve higher compression

Subd, looking forward to an applicable voxel engine with an easy to use UI..

I see you have a Legion Pro 7, I too got a Legion 7 Pro, but I got the AMD variant with the 4090, and got a really good deal on the laptop through a sale. I have been thoroughly enjoying being able to do rather difficult to run things like racing in BeamNG Multiplayer with 16+ players, or pushing Minecraft to stupid render distances with various mods. I'm looking forward to games built on voxel engines like yours, it looks like so much fun to mess around with. I do wanna say one thing, I really want to see flight simulation achieved via voxels. My dream would be a full game with a story, built around the idea of making ultra light aircraft, sculpted from wood, much like a balsa model aircraft, which the player can build and then fly in an incredible aerodynamic simulation, achieved utilizing purely voxels. I currently know nothing about coding, and this dream of a game made around this idea is impossible for me to achieve right now, but I think if I ever do get into coding and working with voxel physics simulations like this, that is what I'd do. I want to capture the beauty of flight, and specifically pure glider flight, in a physics simulation where the air flows accurately up and over mountains to replicate ridge lift, alongside thermal soaring and stuff like that. Idk if you'll read this, but I'd love to know where or how you started down your path in making these kinds of simulations. Your simulation with the ships I think is the closest I've seen to a simulation capable of achieving this idea of mine because the ships appear to be flexible, and destructible, which are both aspects crucial for making accurate glider flight simulation.

This would be a good foundation for a sick waterbending game

6:06 is a great chunky flesh simulation lol

Tip: resample sub-1440p videos to at least 1440p so that RU-vid retains most of the quality of the original upload (more bit rate granted for higher than 1080p uploads). Add also just a tad of sharpening for good measure. I've used VirtualDub2 for sharpening and Lanczos3 resampling. Works well.

Looks great! The water does feel a bit sticky on the boats at the end there though.

that is so impressive! did you have an idea of what sort of game you wanted to make? i was imagining a cool ants nest game where you have to build a nest without it caving in while water comes in periodically lol

With voxels, there are always more boxes to tick!

Wow. Nice work! I have a few questions about your fluid/solid simulation. How do you discretize the domain? Do you have particles like in SPH simulations? Are you actually solving mass and momentum balance equations to have a physically accurate simulation?

Really good job! Have you thought about rendering a lot of simulations, storing them, rate them and use them to train an ai model? As far as I know nobody is currently working openly known on such a project (maybe for a reason). Start small however :) Cheers!

funny words, magic man. ;)

the firestarter 9000

Reminds me of John Lin, hm... very good looking.

in someone else his voxel optimizations he cut down on the floats bytes by just keeping track of the delta relative to a certain chunk saved him 6 to 9 bytes depending..

Do you have a mirror of this video somewhere? I'd love to see it on Vimeo or something, where the compression is less severe

very pretty water

That's some incredible real time particle simulations. Too bad RU-vid compression murders all the detail out of it. I wonder how this would run in a game once everything else is calculated like lighting and other functions

Watching the first 30 seconds its obvious you are using "fractal" simulations by using a few high quality particles and then using rng offsets for the others but I think its a smart choice.

Your work is amazing. I have never seen such a high-quality physical simulation. This may sound a bit rude, but is it possible to view the source code for educational purposes? It would help me a lot

teardown 2 incoming

looks amazing. but, wouldn't it be substantially faster if you did this on the GPU instead of the CPU?

16 times the detail!

If you export your videos with a higher bitrate it should preserve some of the details in the water particles and stuff even in 1080p

This is amazing sim work, but clarify one thing, what do you mean you were super intrigued by intel's cpus and their high core counts ? I really tried listening to that part 3 times but still can't figure out what you mean. I've been using pcs since the days of AMD k6, Duron and Celeron Days. And now I have a Ryzen cpu. The only reason why we have high core counts these days is because AMD broke the almost decade old intel grip on the 4core era. Back to the point : What do you mean by being impressed with intel's higher core counts ? Perhaps you meant some sort of special register that may be unique to intel that helps your specific use case ? It makes very little sense to say intel has more cores since their top of the line desktop chips have a mix of bigLITTLE cores that top at 24threads/cpu whilst amd's top at 32. The enthusiast/workstation chips both Xeon W series and Threadrippers share the same story. The only place where intel and amd share the same nr of threads (not cores) is the high end mobile market but then again amd's offer with 3d-Vcache may significantly help your use case. All in all, you gained one subscriber 🥰 keep up the amazing work !

Cool, But you can just implement the Quantum Mechanics and super optimise them instead (and than you will get all types of materials automatically!) hopefully, and hopefully you can do it , because it's gonna go complex

Please make a sandbox game using this tech.

Is it just me or do alot of people (including me) still run the 8700k, is it that solid?

Houdini/blender/etc: your liquid would calculate for days Some random guy on utub: 6:52 okay we made world scale realtime ocean +_+ jeez dud

Actually 16 times the detail!

all this in 6 months ? pro

Stuff like this equally impresses and depresses me, because I can't begin to imagine how many years I would have to invest to build something even remotely as impressive as this. Very inspiring! Looking forward to future updates :)

i dream of swimming in that water in VR one day! it will happen. it's only a question of time.

How much more time for this to be used in unreal engine 5?

OMFG

6:40 😂😂😂
