Fascinating video! I'm currently using the naïve method of first scaling up by the floored ratio using nearest neighbor and then scaling up the result with bilinear filtering. I need to give your method a try.
I was literally thinking about you throughout this entire video, I even considered reaching out to you about this video as I would love to see you implement something like this in your own game so this is great to hear.
After discovering this channel, I binged the content so hard. Concise explanations, logical flow through the explanations, high production quality, practical applications of concepts... These videos are just superb from both an educational and entertainment perspective. Kudos!
The amount of work you put in this video to teach us something that should be so hard to grasp is insane. As a TH-camr myself, I see all the work there is behind this video and it makes me even more grateful. As usual Tim Soret's recommendations are dope.
Your overview of these mechanics have been very helpful and pretty insightful for my own projects. You are truly brilliant! Thanks for putting out such a wonderful content :)
Dicovered this channel with the absolutely brilliant animation with math video, and it just keeps on providing cool, informative and very well made videos
Never thought of using bilinear sampling as box average. Love your videos, they are unique that you deep dive into heavy math and technical details about niche problems while keeping it extremely approachable and entertaining! Visualizations are well made
Holy... I started re-watching your older videos yesterday, wondering when you'd post a new one because it had been a while and just woke up today to this *GIFT*. Love your content and one of my wish is to develop the skill set to do something similar to what you do. Thank you for the video.
I have been watching youtube videos for about 10 years or so and this is no joke the very best one I have ever seen. The amount of work you must have put into this seems so much! Congratulations!
This was a game changer. I am working in Godot and with a simple translation this shader is working better than any other option, including heartbeasts jitter-free scaling shader. This is perfectly upscaling my 720p pixel art to 1080p.
I've always loved how your videos explain topics in detail while making good use of visual demonstration. Where I would have been stuck on how perspective effects anti-aliasing, I understood in seconds with the warped quadrilaterals.
I'm probably never going to use this specific type of shader ever, but the quality of the video was so good and the production value felt so high that I feel you earned a sub regardless. Incredible video
no video in 10 months, I randomly check out this channel and here you are. I just realised that this is probably how all 3D texture editors work, like blender textured view and substance etc. At least it has the same effect. The effect it has on your game is perfect!
Wow! I made a similar implementation when trying to make multi-colored SDFs, and while I directly went with the fwidth() approach, I hadn't considered updating the uv gradients nor the sampling window! Also having the explanation as to why this works in the first place was amazing! Thank you so much for these videos!
So many titles fail at this scaling issue & when im working & seeing titles come through.. it's a huge pet peeve that these studios cannot figure out what you worded so clearly. Great video! Glad to see this topic arise more, modern pixel genre games all need to take note.
Wow, this was a phenomenal video! Seeing how far your game has developed over the past few years has been great, but these explanations are something in a league of their own. Excellent job!
This guy is slowly teaching me math better than some of my professors. What is referred to as the deformation gradient in the video, is more generally called a Jacobian.
I feel very stupid for having the same problems (for dynamic UI scaling actually) and going with the first algorithm thinking this is good enough. Then encountering all the problems you have adressed in your solution and now realizing I should have just watched until the end and not just vaguely remember. Thank you - this really helped a lot!
thanks! I was motivated from hearing similar struggles from several different teams (RadicalFish, Tim Soret, Aarthificial, ...) so I thought I would really cover all the details one is likely to run into when doing this.
I really appreciate the way you go into great detail about technical aspects that might not seem as important in the grand scheme of things - really perfecting them. I'm sure when this all culminates into your game, you will be able to feel that extra layer of polish. Looking forward to disecting this when I get my hands on it! Great work as always. :^)
This scaling method is also useful in video/image display, in particular for solving the issue of temporal aliasing. The popular video player mpv had the (simplified) version of this scaling method for 10 years, as the name “oversample”, for both scaling and frame mixing. VLC 4 has had it a few years also.
Maaaan instant subscribe to your patreon, wish you good luck with your project! Don't forget to add some content before release (weapons, abilities, enemies), this beatiful game must be played by a lot of people))
I love learning about technical details like this. Excellently presented. Also, looks like a lot of work got done on the gameplay and such, which is looking very exciting!
With so much of modern gaming being for-profit shovelware where the devs just throw together premade asset packs and slap microtransactions on it, I have really learned to appreciate the real game dev pioneers figuring out the math and spending hours on problems that others just live with because fixing it would be too much work. Your game has so many interesting systems that the industry typically deems not cost effective or impactful enough to work on, but they're compounding into something amazing that you typically only see from AAA titles that give their developers the time/money/freedom to add polish (which is extremely rare). Most games would only have 1 or 2 of the features your videos cover and base their entire gameplay around it because of how cool it is, and here you are cramming them into a single game just for small aesthetic boosts. I can't wait to see the end result..
This is cool! I've been stuck on working with OpenGL stencil buffers to achieve something similar to octopath, but its inspiring to see progress in this art style
Thank you! I stg it is impossible to find anyone saying that you can scale pixel art to non integer resolutions! The only exceptions seem to be Casey Muratori, a shader on shader toy, shovel knight, and a video about doing it in Godot by HeartBeast, and even the Godot documentation says it can't be done! Thank you so much for the simple description!
I was pretty unsure at first if your technique was actually prettier than nearest neighboor in my opinion, but turns out that was only an issue because you were zoomed in on a low resolution upscaling. I think your usage of this in the footage you showed of your game was very pretty, super impressed.
ahh yeah it's a bit tricky to balance in a youtube video since everyone could be watching on vastly different devices. I might have over-optimized for small phone screens
I've used several of these techniques, but only had an intuition. Your explanations really expanded my understanding. Your3D stuff looks absolutely stunning, and I'm considering some kind of pixelated look after switching engines from unity to Godot.
I’m about 6 weeks into a class on graphics programming, and this video is a really neat intersection of things I totally understand and things I don’t get at all
I would need a few lives fully dedicated to study shaders to understand this, but even if I got a 2% that's new knowledge for me. Thanks for this superb visuals presentation, and btw your game is shaping up to be a major hit, best luck sir!
Personally, I prefer to have internal resolution set to something like 360p for that pixel KRUNCH. Just a bit annoying to make UI work. But that was a really cool explanation and way of thinking about the filter! Awesome video.
Great video! I'm always wondering why such basics - and by that I don't mean easy stuff, but fundamental requirements for a game engine - are not provided out of the box nowadays.
This is sick! Makes me wonder a little about how a little temporal would look stacked on top of this? Might look like trash and undo eveything, or might actually lessen the effect of "pixel-jumping" when things move or rotate.
I can't wait until this game comes out. I just hope it's going to be open source because then I could make it work for any platform I use and I would definitely buy a copy then. I could see this reasonably going for anywhere in the range $20 to $40 easily.
Excellent way to visually explain very interesting niche concepts! Always love your videos. Perhaps this is handled separately, perhaps not at all, but I’m curious - is gamma correction taken into account when blending colours? Maybe it’s high cost for little change, but I don’t know. It definitely makes it look better, so I’d imagine that if it’s not being used it’s because you looked into it and decided it wasn’t worth it. For anyone else interested, gamma correction is used to adjust light intensity from their display values to their physical values, then do the relevant math, then adjust them back. This is one of the biggest unsung heroes of making video games look more realistic in the last 10~15 years. For an extreme example as it pertains here, suppose you have a checkerboard pattern of 0% and 100% (black and white). Suppose you reduce resolution to half both ways, and now you have a solid grey by mixing half of each, but what does that look like? Intuitively you’d say 50%, but gamma corrected it would be 73%. To understand, get a pixel perfect screen that has the checkerboard in the middle, and each version of grey on either side, then back away or squint until the checkerboard blends into a solid grey. You’ll find that it matches the 73% and not the 50%, which is a result of how our eyes perceive light values. Most game engines and 3D renderers automatically do this now, but most other things do not by default, including OS screen settings and image and video editors. If you made a video about gamma correction I’d share it with everyone.
modern engines do all operations in linear color space and only apply the display gamma at the end. that is also what happens here. (Although parts of the video were authored in a video editing software that operated in rec 709, so in this video you could see some variations, but in practice, nobody's gonna notice if the anti-aliasing has a nonlinear gamma) I probably won't make a video about it because it's a subject others are more qualified to speak about (and tbh, I hate dealing with these sorts of bookkeeping problems)
Very nice video! Congrats on the SoME 3 win. I would have assumed that it would be at least as fast to forgo texture mapping and instead divide a sprite's polygon into smaller pieces that have solid colors (i.e. two triangles or one quad per texel at most, but fewer if multiple texels in a color region can be combined into a bigger polygon). Is that not the case?
Novis game dev enthusiast here. Might is ask from where and or whom you learned and aquired such skills and knowledge? Secondly, if your source/s is out of reach/unattainable for most by either price, availability, complexity, or extrapolation/coherency would it be possible to create a learning class and or course on the web? If not provide or direct us to a list or supplemental courses and or materials or forums you recommend? These questions come from my long love and facination for 2d pixel games and a roadblock i have always have had has been wanting to understand how these sort of things in hames can most efficiently and effectively accomplished while knowing or understanding it deeply. If you read this I thank you from your time whether or not your able to answer and or respond to my questions, requardless... Thanks for the video. 😌
