Previously, Avian has supported f64 with a feature flag that changes almost everything to double-precision. This changes with my f64 overhaul. In short: Use f64 only for world-space values that degrade in precision far from the origin. This approach is inspired by Jolt. github.com/avianphysics...

Minimal Use of `f64` for Large Worlds by Jondolf · Pull Request #1027 · avianphysics/avian

Objective Related to #439. Avian supports both f32 and f64 by using type aliases like Scalar and Vector that choose the appropriate type based on the active feature configuration. When f64 is enabl...

An overhauled Box2D-inspired Continuous Collision Detection algorithm has landed in Avian! It uses a form of swept CCD by default for fast-moving bodies. #physics #gamedev #avian #bevy github.com/avianphysics...

Fast CCD without ghost collisions (Box2D-inspired) by Jondolf · Pull Request #996 · avianphysics/avian

Objective Fixes #990. Currently, Avian relies heavily on Bepu-style speculative collision with an unbounded speculative margin. This has two major problems: This style of speculative collision is ...

I’m happy to announce the release of a new open source 3D physics engine called Box3D. I’ve been working on this project for a few years now, but it represents over 20 years of experience writing physics engines for games. Read more here: box2d.org/posts/2026/0...

Avian has been updated to Bevy 0.19. Have fun! @bevy.org As always, an announcement post can be found here: joonaa.dev/blog/13/avia...

Jolt Physics just hit 10K GitHub stars! What started in 2014 as a CPU vs GPU ray casting experiment became a full physics engine in 2021. Seeing what you’re building with it is amazing. Thank you!

I just released version 0.6 of Avian, an ECS-driven physics engine for @bevy.org. #physics #gamedev v0.6 features move-and-slide, joint motors, and an overhauled broad phase using BVHs, resulting in massively reduced overhead for scenes with a large number of colliders. joonaa.dev/blog/12/avia...

Avian's broad phase collision detection has finally been overhauled to use Bounding Volume Hierarchies from the OBVHS crate! Previously, basic sweep and prune was used. This is a stress test with colliders in a grid moving randomly, rendering the resulting BVH. #bevy PR: github.com/avianphysics...

Initial support for joint motors has finally landed on Avian's main branch! #bevy #physics #simulation github.com/avianphysics/avian/pull/913

I just released version 0.5 of Avian, an ECS-driven physics engine for @bevy.org. This is the first update under our new release process, where we publish Bevy version updates separately from feature releases. As always, an announcement post can be found here: joonaa.dev/blog/11/avia...

A quick blog post on some recent changes and improvements to Avian's development, including new release and migration guide processes, a GitHub organization, and a dedicated Avian Dev Discord server. Also a brief update on plans for the 0.5 and 0.6 releases 😉 joonaa.dev/blog/10/evol...

Avian finally has built-in move and slide, the movement and collision algorithm at the heart of kinematic character controllers! #bevy #gamedev #physics #kcc PR: github.com/avianphysics...

Avian is getting pretty big nowadays! To mark the start of a new release cycle, I spent some time improving our processes moving forward. Notably, Avian now stores migration guides in-repo, similar to Bevy: github.com/avianphysics...

I just released version 0.4 of Avian, an ECS-driven physics engine for @bevy.org. This is the biggest release yet, featuring 3x performance(!), overhauled forces and joints, voxel colliders, Bevy 0.17 support, and much more. As always, release notes can be found here: joonaa.dev/blog/09/avia...

Today, I finally merged simulation islands for Avian! Islands are graph-like structures where bodies are connected via contacts or joints. They are used for sleeping and waking, which is crucial for reducing CPU overhead for large scenes with many dynamic bodies. github.com/Jondolf/avia...

Persistent Simulation Islands by Jondolf · Pull Request #809 · Jondolf/avian

Objective Closes #578. Sleeping and waking are crucial for reducing CPU overhead for large game worlds. Up until now, Avian has used basic per-body sleeping that only allows sleeping for dynamic bo...

Today I merged one of my personal most anticipated improvements to Avian: a parallel solver with graph coloring! github.com/Jondolf/avia...

Parallel Solver With Graph Coloring by Jondolf · Pull Request #771 · Jondolf/avian

I just released version 0.3 of Avian, an ECS-driven #physics engine for @bevyengine.org. Highlights include observable collision events, collision hooks, physics diagnostics, reworked contact pair management, and Bevy 0.16 support. The announcement can be found here: joonaa.dev/blog/08/avia...

Swimming controls and Archimedes' principle 🛟🏊 #gamedev #indiedev #solodev #indiegame #BevyEngine

Implemented some overengineered physics diagnostics for Avian to monitor various timers and counters in real-time, along with a pretty UI overlay for displaying them. This is very useful for profiling and optimizing Avian itself, but will also let users see what time is being spent on.

While working on my game using the #bevyengine, I keep tweaking and iterating on my vehicle controller (using @jondolf.bsky.social's Avian physics) and it's getting close, I can feel it. #gamedev

Over the past week, I've been cooking up lots of improvements to Avian's narrow phase. Contact hooks, a contact graph, bit sets for efficiently processing contact state changes, and overall better and more performant contact pair management.

Avian is an ECS-driven physics engine for @bevyengine.org, with a focus on ergonomics and modularity. I just released version 0.2, which includes a *ton* of new features and quality-of-life improvements. An announcement blog post with release notes can be found here: joonaa.dev/blog/07/avia...
