2:17 How do voxels get "moved up to the front of the array"? You need space for them to land, and you don't want to re-copy the array every time a voxel is moved. You could swap voxels in the array, but then a recently rendered voxel could get swapped straight to the back of the array and get overwritten too quickly.

1:01-1:10 this made me check if my PC was OK

WHERE ARE YOU?

too bad you stopped making those videos :/

How did you learn vulkan?

How did you do it??? Tutorial or explanation/course any time soon??

Rendering voxels is trivial. Moving them and collisions is a whole other thing.

did bro die?

Very nice work! Thank you for sharing.

This is amazing stuff! Thank you for the inspiration!

this looks so cool

this is very interesting. I'm not into Voxels, but I'm working in some custom/compute shaders and I want to try your cache system

😍

How the heck.

very good

oh my god my brain right off the bat. I love it. I want more. It's like a 3d mandelbrot of voxels bro that was straight up like digital psychedelics lmao fuckin digital lsd

Dude, this project is still up? I love voxels and want to make games using this tech, it has any chance to be used by me? I saw tons of voxels engines out there, but most are people like you doing something that i not sure if will become a game, a software project or just a tech demo... I'am a programmer, but i have no enought knowledge on maths to do really heavy optimizations today, any tech like this will help me building a better game LOL

This is exactly the kind of coding video I like. 🎉 interested in continuing to hear more about the unique challenges you face and how you decided to move through or solve them.

Nothing says, "Hey guys, I am doing things!, but screw it all" like, "Hey guys, my sponsor does it better!"

This looks more like you are updating textures.

I hope you try making a delta force like demo.. would be nice to see a modern take on modern hardware

The dude could have sold this engine for big bucks but instead abandoned it

<3

Awesome, also 75fps team lesgooo

I'm confused as I really don't understand the move up to the front part (maybe is just a simplification you did to explain it on youtube). The fact is that your description seems to imply some kind of shifting of everything back when you move something up, but this requires a huge amount of copying and doesn't sound good. To just swap 2 elements you need some kind of ring buffer where you slide the window of what is considered the front and then do the swap to this new front so you don't swap with something that has just been rendered and don't do any further shift.

Dudes so good at making voxel rendering engines he even got one on his wall

so you are using hdd memory instead of gpu memory ?

Incredible. Whenever i see these ludicrous voxel amounts, i always want someone to try just making a standard minecraft clone with it. I am so curious. Will it even be possible? What will the drawbacks be? There has to be a reason nobody has done it!

just fyi, the link to the paper seems to be broken

WARNING TO VIEWERS: I don’t think the author of this video understands the sparse voxel oct tree concept properly, and that is the reason there is no supercover/DDA algorithm for a sparse grid. You traverse the Oct tree to determine if you have a hit, and contact is already encoded in that data structure. It looks like what happened here is mix up the concepts so there’s grid traversal on an oct tree-like setup. If you understand why SVOs are a powerful technique for ray casting, then one would never make this mistake, and certainly not reintroduce complexity to the algorithm. I recommend reading some paper by Nvidia on the topic. You can find them for free.

would love to try your voxel game engine as soon as it's ready to be used

Consider me ignorant on this subject, but if you did all this 2 years ago, why are Voxel games today, as in 2023, so GPU intensive as to usually require 4, 6, or even 8GB of dedicated VRAM just to load the game and get anything close to stable FPS?

Please upload again my dude.

me thinking my 1 million 'voxels' is good:

Wouldn't making the cache as huge as you suggested ("several gigabytes") make things extremely slow? Moving a voxel takes O(N). If you're moving one from, say, the middle of the array (because it hasn't been accessed for a while) it's going to be quite slow with such a massive array. Or am I missing something?

Man where are you ?

meanwhile in the system enterprise world My {insert language } app hello world app need xxgb of ram

this is ingenious!!! keep going, dude!

Just found your channel, and while im happy that you are keeping busy with that job, now im jelous of them for having your time isntead of us, hope you still at your engine and your Dream❤

as taken from his discord "Hey everyone feel like I owe you all an update and announcement with what's been going on over the last months... I started a Job at a startup that I've really been enjoying and there has been so much work going on there that I really haven't had time to work on my game engine and make videos! I wan't to change that but for now I should be upfront in saying that I still wont have much time for another few months... I hope you all understand... I miss making videos for y'all!" this was in 2022 :(

Nice job! If the textures are not so noisy, youtube can deliver better video quality, so we can see what you see!

I am making a voxel game in Rust with the Bevy engine! It has a really nice ECS system.

DUDE THIS IS INSANE!!! You are extremely talented man, and have given me more motivation to keep pushing on with my own game engine

2 years :(

How are you doing man? You've got something great on your hands.
