grgrdvrt @grgrdvrt.bsky.social · 01/10/2026I'm making a small app to learn german vocabulary. I asked Claude to materialize the progress with tiny viennese buildings. Not only it looks really great, but it spontaneously made a small prototype where I can test different configurations 😭 011

grgrdvrt @grgrdvrt.bsky.social · 02/05/2026Still working on my "chain of increasingly complex programming tools". I'm working on V4. One idea for this version is to use the jj graph as the interface to manage the tasks 130
grgrdvrt @grgrdvrt.bsky.social · 10/04/2026I'm late to everything, so I didn't notice the frequent usage of the word "harness" until recently. Apparently it started in november. 230
grgrdvrt @grgrdvrt.bsky.social · 07/04/2026If, like me, you wake up every morning wondering what the Voronoï diagram of arbitrary shapes looks like, here is the answer: 1374
grgrdvrt @grgrdvrt.bsky.social · 27/03/2026After many attempts over years and years, I finally managed to implement Fortune's algorithm for Voronoï diagrams. The step by step visualization was key to debug the process, and when everything work it's just mesmerizing. 4643

grgrdvrt @grgrdvrt.bsky.social · 17/08/2025Last one. I think I have reached the limits of this toy language. I should add a `sort` function to the language to draw the faces in the correct order, but I think more and more about completely rethinking the language and the environment. 032
grgrdvrt @grgrdvrt.bsky.social · 13/08/2025When I decided to only support HSL for colors I definitely didn't have lighting in mind 020
grgrdvrt @grgrdvrt.bsky.social · 12/08/2025- Mom, I'd like to go to SIGGRAPH! - We have SIGGRAPH at home. SIGGRAPH at home: 031
grgrdvrt @grgrdvrt.bsky.social · 12/08/2025Still only edges, but only drawing the ones where z < 0 020
grgrdvrt @grgrdvrt.bsky.social · 11/08/2025Anyway, starting from a linear y (left) rather than phi (right) was a mistake. I removed that code. 010
grgrdvrt @grgrdvrt.bsky.social · 11/08/2025This is just sqrt(1-y^2) Not being able to chain math operations is definitely in the top 3 of things I hate the most about my language. 110
grgrdvrt @grgrdvrt.bsky.social · 30/07/2025Just kidding, the colors are simply flipped based on `(i+j+r)%2` Where i and j are the grid coordinates, and r is a 0 or 1 value that determines the orientation of the tile. 000
grgrdvrt @grgrdvrt.bsky.social · 30/07/2025Added color. This was super difficult because you need to identify the interior and the exterior of each shape by looking at the bigger picture. 130
grgrdvrt @grgrdvrt.bsky.social · 21/07/2025Fixed if/elseif/else constructs for my language. I don't have a notion of "code blocks". A program is a flat list of instructions, indentation is only a visual help and is done by counting the nested for/if/else... 120
grgrdvrt @grgrdvrt.bsky.social · 09/07/2025One of my side projects is a toy programming language+interface for mobile. I need to fix a few small things before sharing it, like having if/else instructions that work correctly or completely rethinking the data inputs... For now, the simplest program looks like this: 081
grgrdvrt @grgrdvrt.bsky.social · 06/12/2024I think this was meant as a reply to a specific post. You have to click on the tiny bubble under the post for that. 😉😉 230
grgrdvrt @grgrdvrt.bsky.social · 08/11/2024Earlier this year I released pictobrush.com. One thing I didn't advertise enough is the possibility to use your own pictures for painting 🎨🫠 293
