I teach C++ & computer graphics and make games. Working on a village building game: https://t.co/skTGGgH0Ay Check out my cozy traffic sim: https://t.co/7Dzc83p6uq He/him

I like how the clouds look in my game, but they severely obstruct the ground view when looking from above the clouds 😓 Adding a "show/hide clouds" UI button seems like a very crude solution. #indiegames #indiedev #gamedev

I've open-sourced my WebGPU shallow water simulator! There's a lot of code, but the core simulation is just about 50 lines of compute shader code. I'll probably write a blog post explaining how it works a bit later :)

Another fun system. Love those little guys escaping the core only to immediately disintegrate

$Sooooo, we finished it: Color Fractory, our submission to #gmtkjam #gmtk2024 jam, is a colorful fractal factory management game. Build conveyor belts to move resources, carefully plan out large production pipelines, and see if you can beat the final level! Link below 👇$

Ah, all the artifacts were fixed by replacing one '&lt;' with '&lt;=', duh. It all works now, particle life completely on WebGPU! There are 2^18 (~260k) particles here; my PC struggles after about half a million particles. Will probably try to optimize it a bit later.

Improved my precipitation algorithm - now it doesn't always rain, but only when water vapour content is above threshold - which means I can visualize clouds! Honestly I didn't expect it to look THAT realistic 🤩 #indiedev #gamedev #indiegames

So I've finished a huge refactoring and everything works exactly as it did before and everything looks completely normal #indiedev #gamedev #indiegames

For optimization, I don't want to simulate water in a steady state (e.g. this lake), but a flat water surface is boring. So I made the vertex shader add random periodic offsets based on vertex pos hash and it seems to do the trick 🥰 #indiedev #gamedev #indiegames

Found this project from 2018. Sort of a voxel editor with a strategy-like top-down camera. Post-processing outlines, some darkening in corners &amp; brightening on edges. It even features some sort of a sky ligting system! Funnily enough the repo is called secret-project, lol

What a lovely little village! Would be a shame if it was just 0.02% the size of the world, right? 😅 #indiegames #indiedev #gamedev

Regardless of the visual style, filling up various lowlands with water is super satisfying #indiedev #gamedev #indiegames

WATER SIMULATION IS WORKING!!! It's extremely non-optimized, and there are still some glitches, and of course the rendering is very temporary, but IT'S WORKING! #indiedev #gamedev #indiegames

Wow, this is just stunning

An alternative water visual style: just a flat-shaded triangle mesh, but keeping the fresnel reflections and underwater fog! What do you think? #indiedev #gamedev #indiegames

First update of my online webgpu particle life simulator: the number of particle types is now also randomized each time (from 2 to 16), leading to greater variety!

Another quite intriguing rule set. This cell almost looks like it has a nucleus

I'm back from vacation (and food poisoning...), so my tree impostor adventures continue. Now precomputing &amp; rendering tight octagonal impostor bounds (instead of full-bbox quad), which saves another ~0.7ms per frame in the scene with ~30k trees! #indiedev #gamedev #indiegames

A new (and probably last) version of my in-browser particle life simulator with some highly-requested features: ✅ Toroidal (aka looping) map ✅ Copying URL to share your simulation with others ✅ Various UI improvements

Really in awe of the stability of this simulator. I left this one overnight and it's still fine, minding its own business

Spawning 100000 shovels for no reason (I'm glad the engine handles that smoothly though) #indiedev

Ok I'm probably pushing this waaaay too far but here's a timelapse of raymarched noise-based terrain with the noise changing over time

First tests with spawning entities on this huge map. The terrain -&gt; trees transition looks meh, but more importantly rendering this many trees really hurts performance, gonna work on that. Amusingly, frustum-culling 300k entities each frame is rather cheap! #indiegames #gamedev

I'm late for ~7 months, but I've finally published my C++ &amp; WebGPU raytracer on GitHub! I've tried to keep the code fairly commented and readable. It works pretty well, but I've never managed to make refractions work with VNDF. Maybe another time :)

Still kinda blown away by the scale of my game's world and all the possibilities it has. Imagine it filled with rivers, deserts, lakes, towns, mines! 🔥 Ugh, so much more work ahead. (please ignore the weird cloud shadows 😅) #indiedev #screenshotsaturday #gamedev #indiegames
