    For particle lighting you might want to try deep shadow maps using Fourier series
    I made an example of this ages ago (search Volumetric Particle Lighting Fort Attack if your interested)
    Another option is using statistics, random and temporal blending. Each frame you randomly select a set of particles to render from the lights perspective then do a standard shadow map calculation and temporally blend the results for each particle. If you have a 100 particles evenly distributed on the lights path and only select one per update then a particle in the middle will be closer to the light 50% of the time giving you volumetric lighting.

    Many familiar topics here, nice to see. Like lerp functions (I think of them as mix functions..) and easing functions (I think of them as transfer functions).. and like, even Affine transformations are analogous to a classic Gain + Offset module in the context of modular audio synthesis.
    Okay and yeah, a possible way to "fix" the noise issue is to use another easing/transfer function on the values of the voxel grid before the occlusion calculation. This is the same problem of Gate signals in modular audio synthesis being too abrupt (especially with digitally controlled ones that can operate arbitrarily quickly), so they're used to control Envelope modules, which give a way to set the rate of change for the rising and falling edges of the signal. This is really important when using an threshold detector on an incoming audio signal to generate gates, because otherwise super brief changes in the signal level can produce large changes in the output level... anyway yeah, interesting to see more and more analogous operations.. almost as if they're the same topic but over different domains or something hehe.

  • @isned2000
    @isned2000 หลายเดือนก่อน +5

    One thing to note about the tiny triangle quad overdraw problem, it probably wasn't a big deal in the particle case because the particles were not texture mapped. The GPU only does the full quad finite differences pass if the fragment shader reads an interpolated attribute like texture coordinates, solid color triangles don't pay the cost.
    In general the tiny triangle inefficiency only becomes a problem in very specific cases, the performance tax it incurs depends on the way the rest of the rendering pipeline is set up. The more work that is done by the triangle's fragment shader, as opposed to a full screen pass later, the worse the performance hit, MSAA magnifies it. Microtriangles need special considerations in the most extreme conditions, like UE5's Nanite, where every triangle is a microtriangle by design, or VR rendering where frametimes are small and everything is rendered using forward rendering with lots of MSAA, (basically the quad inefficiency worst case) but you really don't need to worry about it in the general case. A game isn't running slow because of one really dense model, or even a few really dense models.

    Dude, your videos are so lit. Never touched graphic design and probably never will but I do like video games and I love peeking into how this aspect of them is created through your videos. I really like how you navigate between idealism and pragmatism in your approach and the examples you create always turn out really aesthetically pleasing.
    Also from an educational standpoint you impress me in a big way, especially with the math heavy parts. A lot of the time you are explaining concepts that are totally novel to me and 1) you're able to make me interested in and end up understanding a lot of what you cover, and 2) even when something totally goes over my head, I never feel like I've lost the thread and the rest of the video is incomprehensible. You always tie stuff into the overarching goals/ideas that people with zero relevant background can grasp.
    Besides, even though strictly the topics themselves are unlikely to ever be useful to me, I feel like your videos legitimately have taught me some really valuable perspective about approaching big, complicated problems that I can apply to my own creative ambitions.
    Thanks for making these!

    hey acerola, i have been studying dynamical systems in my free time these past few months and a really interesting project you could do that is equivalent to this, is modeling state space diagrams of dynamical system. nonlinear dynamics, and chaos theory(ding ding ding!! you just dipped your toes in it with this video) would be a really fascinating computer science and computational difficult problem at reasonable compute times. Like a live mandlebrot set, or whatever other maps. all sorts of cool orbits, cycles, attractors and the like to explore. especially if given some dynamical system, could freely explore certain systems and investigate their structure. anyways, really cool video as well. super neat stuff

    My biggest pet peeve right now in graphics is the use of blurring effects to hide inefficiencies. I get that it would be too costly to generate things without noise and dithering, but I just hate how the results look. I have not ran into an implementation of TAA that has looked good to my eyes, including upscaling like DLAA and such. I like how ray tracing is being pushed more, but this transition time that relies on dithering and other noise effects to hide the performance impact cannot end soon enough.

      @@Acerola_t I get it, but I just feel that the older methods of hiding them were better than the current temporal methods. The way that they are implemented now means that there is not even the option of turning off the temporal effects without destroying visuals completely. So you just have to put up with smearing instead of the jaggies of before. I preferred jaggies since there are multiple other ways of hiding them - like a simple increase in render resolution once hardware gets better.

    • @cataclystp
      @cataclystp หลายเดือนก่อน +5

      @@Zyxlian you're looking at them with rose-tinted glasses. Old games were aliased and jaggy as hell, and no, increasing resolution doesn't make the problem go away, it just makes it smaller. That doesn't count since in this case, the resolution of your screen has no relevance to the resolution of the particle system. I get that TAA is the new biggest thing for everyone to pretend to be an expert on, but the truth is that these are new problems that weren't feasible before due to limitations of hardware. "Old methods" didn't do particle systems like this better because they literally were not possible on old hardware. You're literally looking at a novel technique that hasn't been done before and saying "well back in my day things were done better!!!" while failing to understand what the word "novel" means

    • @Zyxlian
      @Zyxlian หลายเดือนก่อน +4

      Sorry, I don't mean to come off as rude, I think the particle systems shown here is really cool. I just got irked about handwaving the performance impact of it by implementing TAA. I get that these techniques to push the visuals in graphics are always going to be ahead of the hardware (I was working with ray tracing implementations in the early 2010s, where it took several seconds to render frames). I just hate how there is an increasing number of games where the implementations of these effects are locked on, and the solution to the significant performance impact is to just decrease the resolution and add blurring. What's the point of ray tracing or particle swarms if they just end up being displayed as a dithered blur?
      As for my increase in resolution comment, I was thinking more along the lines of increasing the amount of particles in the swarm. In the sense that future hardware will be able to render more particles natively. By implementing the feature in a way that, even with this increase in particles and hardware performance, will still be blurry/dithered no matter how performant the hardware is, just seems counter-intuitive to me.
      I just want the option to turn the blurring effects off without destroying visuals.

    This is so insanely cool! I study chaos game and its relationship to IFS for my PhD, but I never would have expected these topics to come up here! I use chaos game to represent genetic information, thus producing a unique fractal out of it - which I then use as input for all sorts of analyses like convolutional neural networks. I do all of this through the lens of virology, as I use this method to study how COVID-19 evolves in real time (real time being every few days because the gov won't let you sample people too often) in response to different pressures - like antiviral treatment! I hope someday to make something so visually intuitive for my research, and this video has given me plenty of ideas on how to do exactly that - huge thanks!

    ooo i actually did a similar thing to the sierpinsky triangle example you showed, like 7 years ago or something after seeing a demo on numberphile where they had three target points and one moving point, and you're just rotate the one moving point towards one of the target points (literally at random) and moved it halfway there, then you'd plot its position and repeat the steps. the moving point very quickly (like within three or four iterations) moved itself into the triangle fractal area and then stayed there no matter what. I experimented by using more than 3 points, as well as changing just how far towards them the moving point would move instead of "halfway thhough", and got some very cool results. - EDIT: HAH it was their Chaos Game video from 7 years ago, I was right! The way I did it back then was much more inelegant though, I simply opened gamemaker and rawdogged a surface with draw_point calls, which is all CPU bound _and_ incredibly slow (it's slightly faster nowadays but i still wouldn't recommend it lol)

    actually, I suspect some splatting, perhaps even gaussian splatting, could work for games if you don't do it every frame, but like, use it as a basis, much like videos have keyframes and then a bunch of change frames that only modify parts of the frame...
    like you quickly chaos game the general scene very broadly, then splat a mostly-done scene over it, then quickly chaos game the approximation of details, and then do a little bit of something more, like use low-poly models and traditional rendering to map the result to a model, and for the next couple frames, you could just figure out a few changed areas, and do the chaos details + lowpoly, and perhaps re-splat the changed areas every say, 5th frame, or 10th frame? maybe even like every 30th frame or so...
    I'm not smart, but I think some sort of combination thingie like this could actually work, not necessarly exactly as I described, but something a bit similar...

    Neat! I did something similar for a VR prototype a couple years ago, though I just transformed the previous eye buffers instead. That means you lose a dimension from the transformation each time, but that adds some really weird effects to it. (especially in stereo) It's basically like a VR version of the infinite mirror effect. :) Instead of points I drew a few hundred little meshlets each frame which would then get multiplied in successive frames instead of doing the whole IFS in a single frame. This made it _extremely_ cheap to compute on mobile VR hardware.

    Honestly, as an artist that has been feeling kinda bored with a lot of the standard formulas for what makes an aesthetically appealing picture, this is extremely inspiring to me. Look how many infinite shapes there are left to explore that no one has ever seen before.. look how extremely complex yet also somehow simple the shapes can be.. it's amazing.
    Now i just need to get myself to experience this same sort of inspiration regarding colours- heh. Part of the problem (but maybe also part of the solution, limitation does breed creativity) being that there aren't infinite colour combinations out there that are visible to the human eye. This has somehow put a mental block in my head that makes exploring the wide variety of colours we *can* see into a less interesting task.
    When everything is simultaneously infinitely deep yet infinitely shallow, sometimes it's hard not to become apathetic, even when you want to care because it's simply more fun that way. Because obviously the world was never *actually* running out of new shapes or new ideas, it just felt like they didn't matter or couldn't be that interesting.
