@nicbarkeragain There's some fallback to using rationals in FLINT (Fast Library for Number Theory) in the certification of an LLL lattice basis reduction (which can be used e.g. to factor polynomials over the integers): fredrikj.net/blog/2025/opti…

Anyone know of examples of actual fractional arithmetic being used in software to reduce accumulated error? e.g. storing both numerator and denominator of something like 1/3 seperately, and doing algebraic multiplication rather than reducing to a single float.

Godot Engine 4.4 is finally here! 🚀 Look forward to plenty of quality of life improvements hidden within this release. Faster load speeds, reduced stutter, streamlined processes, and more! godotengine.org/releases/4.4/

@lentsius_bark Hey, where did that card come from? From your SLEEVE?

We got reports of a card not showing up properly... Turns out it was there the whole time!

@jrouwe 🎉🎉🎉

JoltPhysics v5.2.0 is out! Amongst other things, it includes a new tapered cylinder shape. Check out the release notes at github.com/jrouwe/JoltPhy…

@RyhonDev @lawnjelly Yes.

3D physics interpolation landed in the master branch 😎 @lawnjelly #GodotEngine #gamedev #indiedev

@passivestar_ @lawnjelly Interpolation of fast rotations (relative to the physics tick rate) is not yet fixed. We should decide how to deal with it soon.

@riburing @lawnjelly Was rotation glitching fixed? 😮

@AHappyDragon @godotengine The 3D physics interpolation PR github.com/godotengine/go… was finished *after* the feature freeze for 4.3, which is why it's not included in this release.

@godotengine Where is physics interpolation for 3D Physics? I feel like this is one of the most important things ever 😒

📅 259 days 🧮 3,520 commits 👤 521 contributors We present to you: Godot 4.3 ✨ godotengine.org/releases/4.3/ We hope you enjoy the new release page format as much as we did preparing it!

@MajorMcDoom break_me

@keaukraine @lawnjelly I haven't used other engines in a while but at least Unity has it built in too.

@riburing @lawnjelly That's actually a great feature. What other popular engines support this kind of optimization?

3D physics interpolation for Godot 4.x just dropped. (Originally implemented by @lawnjelly for 3.x.) #GodotEngine #gamedev #indiedev

@SnkyGames @lawnjelly That's it! There are some subtleties about which interpolation type to use and when to reset/teleport. And you want to make all this work with as little extra work from the user (i.e. gamedev) as possible.

@riburing @lawnjelly to do interpolation, the extra render calls predict where the physics would be at that frame and draw the in-betweens? Is it more than that?

@PorteuseGateaux Merci d'avance de tester !

@Carel3DS @lawnjelly Is it at the beginning or at the end? Could be something funky going on.

@riburing @lawnjelly That frame wth

@greenfox1505 @lawnjelly To be precise, you would define myproperty_curr and myproperty_prev as member variables, update them in _physics_process (myproperty_prev = myproperty_curr; myproperty_curr = ...), and interpolate between them in _process using the interpolation fraction.

@greenfox1505 @lawnjelly Specifically it's interpolating transforms (position, rotation and scale) only. If you need, you can retrieve the interpolation fraction in _process to interpolate arbitrary properties (this is already possible for a long time).

@The_MrX_ @lawnjelly If you set the physics tick rate high enough for your screen refresh rate it will look smooth too. The point is: that's more expensive than doing this interpolation (moving smoothly from one position to the other on frames rendered in between physics ticks).

@riburing @lawnjelly Wait what? What does it do exactly? Why is it smoother/less jerky? Shouldn't that just be how the physics is applied by default?

@lawnjelly PR: github.com/godotengine/go… Testing is welcome!

@MajorMcDoom Doing it this way is future-proofing for the future where physics interpolation is implemented!

@passivestar_ @fergicide It's time to check again then 😁

@fergicide it's possible that it'll happen in the near future. there's big interest and godot-jolt is near feature complete. last time I checked it only lacked support for soft bodies github.com/godotengine/go…
