@jdh what's your opinion on Rust? Personally, I used to listen to the memes then tried it myself about a month ago and enjoyed it a lot.

This is such an awesome devlog, you're one of my faves! I've played around with voxels in Unity and it's not easy lol I'm excited to see where you take this

[@SmoothieBuns]

Thank you so much for making this video. I was about to cry because I couldn't figure out where the flickering was coming from, but it's the backend :')

[@WannibeManisha]

Ohh thats cool! Honestly not surprised you moved to building your own engine in Rust. Really great job and excited to see where you take this!

[@Tantandev]

Haha yeah I was thinking, some people probably could have guessed I would try something like this at some point

[@mikael808]

Really cool video! I like that you show how you made it, it is really interesting to watch! :)

[@flyingsquirrel3271]

Impresive project! Looks like RIIR is not just a meme :D I can definitely relate to your decision to try this. Actually that's probably the biggest downside of rust: Once you know it well enough, you want to write EVERYTHING in it. At this point pretty much every other language just feel unsatisfying and brittle to me.

[@Tantandev]

Haha yeaah Rust messes with my head when I go to other languages, I want me Enums :p

[@onichan6897]

Coming from dynamic language,. Rust have a steep learning curve, borrow checker is a pain to deal with at first, but when I finally get it my code is so much cleaner.

[@ThunderYorn]

Heeey Tantan amazing video as always, it's really nice to follow your progress with rust and the voxel game. The animations that you put in the video were really pleasant, I really enjoy the rhythm of your videos :)

[@Tantandev]

Means a lot! Your comments always cheers me up!

[@arkansaatolo1666]

omg, I love these little animations everywhere! This is amazing

[@Zac8668]

This video is so nice! You inspired me, downloading rust rn, can't wait to try it. Update: I'm following the book and damn is kinda complicated, for me at least that just used python lol, but I'm enjoying, gonna get the basics of the language and try to find a PyGame for rust and make some games.

[@Tantandev]

Hope it goes well! You can ask away in my discord if you need help, we are friendly :)

[@Zac8668]

@blot Still programming on it :) really nice, really like it and even did some gigs with game dev on it, the pygame for rust is Macroquad ;)

[@sombrastudios]

Hey Zac, 9 Months later now, how is it going?

[@sanderbos4243]

Very cool devlog, thanks!

[@kjpg7413]

Adding to my other comment, also IMO we should teach people to use the Simplex-type noise options in these libraries, and seek out libraries with them (FNL has it), to avoid Perlin's tendency to align features with the grid directions. Perlin has had a stronghold in the PCG community for not very good reason, when there are functions out there better suited to more purposes.

[@Tantandev]

I will definitely explore more noise functions! what is FNL?

[@kjpg7413]

@@Tantandev FastNoiseLite. Successor to FastNoise. It's open source (github). The simplex-type noise functions in it are good for producing less visible grid following, and the domain rotation options in it are good for making the 3D functions that otherwise look griddy: Perlin, Value, and Value-Cubic) look good in 2D plane slices. (Using the 3D evaluator function)

[@eboatwright_]

This is really interesting! You're really good with this stuff. :)

[@blugatroff593]

This is really cool! I, while learning wgpu also made a small Voxel Engine and it's fun seeing how you implemented yours. A little story: I was curious about the performance of my Engine and generated a whole bunch of chunks and rendered them at the same time, I was really impressed with the performance (I guess the great performance of Rust can make up for my noobish coding) and started adding more and more chunks until it suddenly crashed. The error message from was something like "not enough memory", i was confused because I was hardly using 100mB of RAM and didn't realize the error was talking about VRAM xD. Next time i ran the program i looked at the vram usage and sure enough it managed to fill up the whole 6GB of my GPU. After thinking for a little too long about why this could be i realized that: something like 500 Chunks * at least ~2000 Vertices per chunk * 8 f32s per Vertex * 4 bytes per f32 = A whole bunch of bytes. So I managed to cram all of the information of a Vertex into one u32, 6bits for each coordinate 0-31, 3 bits for the normal and the remaining 11 for an index into a uniform storage buffer which stores the UVs. I have to be honest, i was quite proud of me that day and it did actually solve the memory problems. I am really curious how you will continue developing your Engine, it would be absolutely amazing if you can translate even just the some the features of your Unity Voxel RPG into Rust and make an actual game. My projects rarely last beyond the experimentation stage. Great video and channel overall!

[@Tantandev]

What a great story to read! Next up is looking at optimization, I will keep this in mind

[@WorstDeveloper]

7:04 - You have a typo in your code. "set_density_fraciton"

[@pxolqopt3597]

The one bad thing about code autocompletion is typos like this won't be discovered for a long time

[@stormbringer1330]

So coooool. Thank's. I learn rust right now, and your voxel engien look's really great, and inspirating for me. Thank's a lot for your sharing. I hope, you will continue to talk about your engine. Good job and keep courgage for the next steps.

[@Tantandev]

Thank you! I'm next going to look into optimizing the code which will be super interesting, I think atleast haha.

[@jupyter_core9411]

Awesome video man! I saw the guy who made Assetto corsa using wgpu-rs to build his next game. I thought about about using it to mess around with building a voxel engine but ended up on the c library raylib. I want to try and understand how a voxel engine works before diving into graphics programming.

"I end up writing unoptimized bad code because it is fast and easy to do, and in the end, it ends up harder to work with."

[@grillad5]

Great video! Great information about the process even i understood :)

[@SergioRibera]

Wow, that's very amazing

[@trinidad17]

Interesting project, specially given the need to learn rendering by yourself. The only problem I have with this is that those are what I like to call boxels, not fully fledged voxels. In the same way that a bitmap is not just back and white, but have values in between and even representing not just grayscale but colors which are not even linear, the same can apply to voxels. A voxel "image" can define a scalar field, like those used for MRI images and rendered smoothly either using threshold values which probably now is totally doable using just shaders, but the easier way out is using marching cubes over that scalar field in order to render it using polygons.

[@amjadiqbal478]

I've recently started dabbling with developing a game without an engine, and I thought it was a good idea to use vulkan directly. But turns out wgpu probably is a better idea :)

First, great vid as usual. One question, why no Bevy? Would Bevy have made it faster or harder to do this project (I am not a game developer, so, just curious).

[@Tantandev]

Bevy might have been a little bit faster due to not requiring as much graphics rendering knowledge (maybe), but my goal is to better understand how it works as low level I can, because I find it really interesting.

[@JeremyChone]

@@Tantandev Makes total sense. Thanks for the answer. Cool channel!

This is not a voxel graphic, it uses a polygonal mesh that simulates voxels, for a full voxel graphic, you need to use a 3D point tree and recursive ray casting (for relistic rendering) 🤨
