Hi! Some of you know that one of our biggest accomplishments here at the Brazilian National Institute for Space Research (INPE) was to build a validated satellite simulator that is being used in all phases of the attitude and orbit control subsystem (AOCS) development. I always knew that one day I …

The integration with PrettyTables.jl was so easy :slight_smile: [Captura de Tela 2026-03-24 às 14.11.25]

Being able to use Kitty graphics in the terminal with almost no slowdown as we have in Tachikoma.jl is a huge win! I can already imagine so many cool things we could do with this kind of feature.

That looks awesome. What were the main reasons for you to implement the UI as TUI instead of a GUI or a Web based solution?

Thanks! I tried a few different approaches. Here’s what I learned: The first idea was to use QML.jl. However, it turns out that QtGraphs is licensed as GPL. Hence, the entire simulation would need to comply with GPL when shipping it, which is a no-go. Then, I switched to Genie.jl. It was easy to …

and how do you plot? is it possible to use Makie in Tachikoma?

@prittjam Yes, and I also fixed the issue with GLMakie earlier today. I’m also working on a new backend TachiMakie but it’s not quite ready yet.

In Tachikoma.jl you can easily copy the GLMakie framebuffer and show it using Kitty graphics. Hence, it is blazing fast! Way faster than using CairoMakie.jl.

INPE's satellite simulator UI is now powered by Tachikoma.jl, and it is amazing!
