#xpbd — Public Fediverse posts

I fixed the problem with the energy 😅

I also ported the code to use f64 everywhere instead of f32 for physics.

2^14 spheres this time ✨

I also made the repository public but it will not be published as a library. It is just my educational progress with my thesis:

Progress with my physics from scratch in #Bevy 😇

I was asked to simulate one sphere and plot its energy to validate my physics implementation.
But since I use #Rust, I thought why not simulate 10000 spheres instead? 😂

I don't understand the energy spike at the beginning, but at least the energy is stable later.

I am following this fantastic #XPBD tutorial in #Bevy by @johanhelsing and I highly recommend it after learning some of the basics of Bevy 😍

The tutorial isn't complete yet, but the first 6 parts are already a lot of material!

The attached GIF is the result of the first part ✨

@johanhelsing thank you for this treasure 🥰

PS: I know there is the physics library bevy_xpbd, but I want to implement XPBD from scratch for learning :D

Been going on a tear with #pico8. Here's an XPBD library with 4 little demo scenes.

@chrisbiscardi Well documented cautionary tales like these are extremely helpful.
Thank you for posting them!

I'm making my own bevy_ecs-based (#xpbd) physics engine for cargo space. Wrote a post about tilemap collision, one-way platforms and how I implemented and optimized the collision broadphase.

WIP on new #GenerativeArt animation inspired by:

- American Beauty (plastic bag scene)
- Betta fish
- Ribbon gymnastics
- X-ray luggage scans
- Halftone & Moiré patterns
- Reaction-diffusion
- Cellular automata
- Dots/single shape only

This piece lives from motion, so a little video... To save file size I re-encoded as 30fps, though actually runs at 60, even on iPhone 11...

Tech details: 68k particles, 122k springs, #XPBD #ziglang #WebAssembly #WebGL2 #ThingUmbrella #DANZA
