Vulkan Backend, IK Spiders, and holiday voxels
2024-11-11
The release candidate process continues, which means more stabilization PRs and small bug fixes this week for the most part.
wgpu 23 was released and is now merged for Bevy 0.15. Animation Blending had some blending weight changes to make the blending more reasonable to reason about.
In the community showcase this week there's multiple inverse-kinematic spiders, the holiday season is starting to rear its head, and a really interesting Vulkan backend for Bevy that I'm hoping to see more of in the future.
The Testbed
Some examples are moving to The Testbed, which is really just another folder in the Bevy repo. If you're looking for "more" than the hundreds of examples already in the examples folder, you can now find some of the more "here's a whole bunch of API usage" examples in the testbed.
Alice's Merge Train is a maintainer-level view into active PRs, both those that are merging and those that need work.
Showcase
Bevy work from the #showcase channel in Discord and around the internet. Use hashtag #bevyengine.
Procedural real-time engine vrooms
showcase
A rough estimation of a 3 cylinder engine crossed with RC car, procedural track, and controller built on avian.
Falling Sand Simulation Engine
showcase
A longer look at a falling sand engine using bevy_ecs, wgpu, and rapier2d. The demo includes a number of rooms, spraying particles, and a character running around.
BioVision Hierarchy viewer
showcase
A BioVision motion capture format viewer written to make sure the units and other data were correct.
Vulkan render backend
showcase
This Vulkan rendering backend for Bevy is a mostly GPU driven renderer with multi-draw indirect, bindless, and GPU culling, that supports most of Bevy's standard material as well as a significant portion of Blender's material system. Materials are fully dynamic and not defined at compile time. It currently uses the screen-13 crate and supports Windows, Linux, and macOS M-series (via moltenvk). There's a whole lot of great discussion both about this renderer and about Bevy's rendering in the Discord thread, so I suggest checking it out if you're interested in rendering internals.
As of this posting, the code is closed source.
Inverse Kinematic Spider Sandbox
showcase
Procedural terrain generation and an inverse-kinematic driven spider, powered by avian 3d and bevy_mod_inverse_kinematics.
