AlkanenManaged to totally break rendering while working on stacking post-process effects. I think it looks cool though.

AlkanenI was reading about the Vitruvian Man and thought why not a Vitruvian Bicycle? It did not turn out as artistic as I imagined but I still think it is a good attempt.

AlkanenI never realized cylinders could be this versatile. These are all cylinders with different sector counts. I guess if you can only have one primitive mesh type in your game, it should be a cylinder. <a href="https://mastodon.art/tags/rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#rust</a> <a href="https://mastodon.art/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a> <a href="https://mastodon.art/tags/rendering" class="mention hashtag" rel="nofollow noopener" target="_blank">#rendering</a> <a href="https://mastodon.art/tags/cylinder" class="mention hashtag" rel="nofollow noopener" target="_blank">#cylinder</a> <a href="https://mastodon.art/tags/rustlang" class="mention hashtag" rel="nofollow noopener" target="_blank">#rustlang</a> <a href="https://mastodon.art/tags/forma" class="mention hashtag" rel="nofollow noopener" target="_blank">#forma</a> <a href="https://mastodon.art/tags/generativeArt" class="mention hashtag" rel="nofollow noopener" target="_blank">#generativeArt</a> <a href="https://mastodon.art/tags/creativeCoding" class="mention hashtag" rel="nofollow noopener" target="_blank">#creativeCoding</a>

AlkanenIt's a lot of fun figuring out rendering basics through trial and error. Fixing the UVs and normals for a cylinder was much harder than I thought. It's still not perfect because of missing seam vertices but good enough for the next step. <a href="https://mastodon.art/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a> <a href="https://mastodon.art/tags/rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#rust</a> <a href="https://mastodon.art/tags/rendering" class="mention hashtag" rel="nofollow noopener" target="_blank">#rendering</a> <a href="https://mastodon.art/tags/rustlang" class="mention hashtag" rel="nofollow noopener" target="_blank">#rustlang</a> <a href="https://mastodon.art/tags/forma" class="mention hashtag" rel="nofollow noopener" target="_blank">#forma</a> <a href="https://mastodon.art/tags/creativeCoding" class="mention hashtag" rel="nofollow noopener" target="_blank">#creativeCoding</a> <a href="https://mastodon.art/tags/generativeArt" class="mention hashtag" rel="nofollow noopener" target="_blank">#generativeArt</a>

AlkanenGot carried away with mazes and ended up adding them to my renderer. Each frame generates a new maze on all faces.

PoireHi everyone.I apologize if the updates are slow, but my brain just doesn't work during heatwaves and also I've decided to switch to a full rust stack.I moved from Vulkan/SDL/Imgui to WGPU, Winit and Egui.As you can see it's going well<a href="https://mastodon.social/tags/rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#rust</a> <a href="https://mastodon.social/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a> <a href="https://mastodon.social/tags/gamedev" class="mention hashtag" rel="nofollow noopener" target="_blank">#gamedev</a>

John-Mark GurneyReally wish there was an easy and/or documented way for me to see what the shader program gets compiled to. Partly so I can understand the GPU architecture better, but also to know how it's compiling and optimizing the code.I have gotten naga to run and convert to metal, but still, it's not compile/optimized yet.<a href="https://flyovercountry.social/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a> <a href="https://flyovercountry.social/tags/WebGPU" class="mention hashtag" rel="nofollow noopener" target="_blank">#WebGPU</a>

AlkanenWorking on mazes on the side gave me a new idea for fōrma that needed texture support. It was long overdue anyway.

Kernel BobAfter two solid days of hacking, I've got a simple canvas that I can draw on. In Rust, using wgpu, running on a Mac. Now I can actually start working on reaction diffusion.Rust calls C for the actual pixel painting. I will implement the actual R-D code in C, too, because this is ultimately going to run on an ESP32 with a touch screen. That's also why the canvas is such an odd size. 240 × 280.🧵 6/N<a href="https://chaos.social/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a> <a href="https://chaos.social/tags/rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#rust</a> <a href="https://chaos.social/tags/MacOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#MacOS</a> <a href="https://chaos.social/tags/ReactionDiffusion" class="mention hashtag" rel="nofollow noopener" target="_blank">#ReactionDiffusion</a>

Kernel BobBut this thread isn't about the wgpu cube. That's just the introductory anecdote.Today I started another Rust/wgpu project and remembered how very hard this stuff is. wgpu is at least 0.4 on the Vulkan scale of overengineered complexity.This is going to be an exploration of reaction-diffusion algorithms, and just maybe fluid flow. I'm using wgpu as a way to get 2D pixels onto the screen.🧵 5/N (reposted to attach this toot to the thread)<a href="https://chaos.social/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a>

Kernel BobHere's a short video. And yes, this is where my Mastodon avatar comes from.In 2018-19 I made an actual LED cube from panels, 3D printed parts, and electronics. This app was originally going to be a simulator for new light patterns, but I got carried away with the visual effects and never got around to any patterns except the bouncing bands.<a href="https://makertube.net/w/fXb6YiGxeZjZLrG27AphCm" rel="nofollow noopener" translate="no" target="_blank">https://makertube.net/w/fXb6YiGxeZjZLrG27AphCm</a>🧵 2/N<a href="https://chaos.social/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a>

Kernel BobIn 2022 I explored wgpu and made this rotating cube demo. In the last three years, it stopped running. Today I debugged it and got it running again. I didn't actually find the bug, but narrowed it down to a dependency. I upgraded the dependency I was using by 37 versions and rewrote my code to use the current API.Anyway, it works again. I'd forgotten what a lot of work I'd put into this.E.g., note the reflected glow on the floor and the bloom around the LEDs.🧵?<a href="https://chaos.social/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a> <a href="https://chaos.social/tags/rust" class="mention hashtag" rel="nofollow noopener" target="_blank">#rust</a>

John-Mark GurneyWell, I'm half impressed with wgpu. It managed to compile fine on my 9 month old version of rust, and a few of the demos worked, but not all of them.Just over half worked, 15 of 29. (Note that I assume that an example worked if it popped up a window to show me something. If the example just prints something out, I might have considered it a fail. Also, this may be because the ray tracing support is experimental, and 6 of the tests are of this type.)<a href="https://flyovercountry.social/tags/wgpu" class="mention hashtag" rel="nofollow noopener" target="_blank">#wgpu</a> <a href="https://flyovercountry.social/tags/GPUCompute" class="mention hashtag" rel="nofollow noopener" target="_blank">#GPUCompute</a>
