    I really enjoy the website content and appreciate the hard work to create it. Also, thank you to the author for taking action on the HN feedback last year about the AI thumbnails that used to be all over this site. [0]

    The website has come a long way, a good reminder for Santa to drop a donation.

    Computer graphics needs more open education for sure. Traditional techniques are sealed in old books you have to go out of your way and find; Sergei Savchenko's "3D Graphics Programming Games and Beyond" is a good one. New techniques are often behind proprietary gates, with shallow papers and slides that only give a hint of how things may work. Graphics APIs, especially modern ones, make things more confusing than they need to be too. I think writing software rasterizers and ray tracers is a good starting point; forget GPUs exist.

    Also, slight tangent, but there doesn't seem to be any contact method here other than Discord, which I find to be an immediate turn-off. Last time I checked, it required a phone number.

    The donations page could use a link directly from the homepage too.

    Graphics have been a blind spot for me for pretty much my entire career. I more or less failed upward into where I am now (which ended up being a lot of data and distributed stuff). I do enjoy doing what I do and I think I'm reasonably good at it so it's hardly a "bad" thing, but I (like I think a lot of people here) got into programming because I wanted to make games.

    Outside of playing with OpenGL as a teenager to make a planet orbit around a sun, a bad space invaders clone in Flash where you shoot a bird pooping on you, a really crappy Breakout clone with Racket, and the occasional experiments with Vulkan and Metal, I never really have fulfilled the dream of being the next John Carmack or Tim Sweeney.

    Every time I try and learn Vulkan I end up getting confused and annoyed about how much code I need to write and give up. I suspect it's because I don't really understand the fundamentals well enough, and as a result jumping into Vulkan I end up metaphorically "drinking from a firehose". I certainly hope this doesn't happen, but if I manage to become unemployed again maybe that could be a good excuse to finally buckle down and try and learn this.

      I feel the same. I was trying to make some "art" with shaders.

      I've got inspired by Zbrush and Maya, but I don't think I can learn what is necessary to build even a small clone of these gigantic pieces of software, unless I work with this on a day to day basis.

      The performance of Zbrush is so insane... it is mesmerizing. I don't think I can go deep into this while treading university.

      Try WebGL or better, WebGPU. It's so much easier and all the concepts you learn are applicable to other APIs.

      https://webgpufundamentals.org

      or

      https://webgl2fundamentals.org

      I'd choose webgpu over webgl2 as it more closely resembles current mondern graphics APIs like Metal, DirectX12, Vulkan.

        Yeah you're not the first one to mention that to me. I'll probably try WebGPU or wgpu next time I decide to learn graphics. I'd probably have more fun with it than Vulkan.
