Bevy 0.13 out now!
2024-02-26
Welcome to another week in the Bevy ecosystem!
This week we've got the Bevy 0.13 release! That means a whole lot of crate releases that upgrade compatibility.
Don't forget to check out the official release notes which include in-depth guides for migrating as well as dives into some of the amazing new features like Lightmaps, Irradiance Volumes, and the new primitive shapes!
Bevy currently releases once every three months (approximately, there is no set date) and this is the first release of 2024.
Showcase
Bevy work from the #showcase channel in Discord and around the internet. Use hashtag #bevyengine.
"Furniture Mode" in Project Home
showcase
Project Home is a life simulation game with over a year of work in it. This showcase demos furniture placement.
Flappy Bird 3d
showcase
A classic flappy bird implementation in 3d, using a gun firing as the mechanic for "flapping".
Colony Sim Voxels
showcase
Voxels! This time for a colony sim type game, which includes being able to see underground. The video in the Discord thread includes a vertical slice animation that is very nice.
Integrating bevy_mesh_terrain and space_editor
showcase
bevy_mesh_terrain is a plugin for terrain and space_editor is a plugin for prototyping with prefabs. Combining them results in this demo. The forked space_editor lives on GitHub.
Design terrain, save file, import RON data.
Erosion Simulation
showcase
Simulating erosion with some nice UI and visualization to go with it. Includes conservation of momentum. The input is Perlin noise summed at several scales.
The two maps on the side are water volume map (black-teal) and water momentum map (grey with red/blue streams)
3d suspension with bevy_xpbd
showcase
A continuation of the bevy_xpbd_2d suspension also featured in this issue,
The Discord thread links to a discussion of possible solvers
Project Harmonia windows
showcase
Project Harmonia is a work-in-progress life simulation game. This demo showcases the ability to place windows with transparency. Models are imported from Blender.
Performant Voxel Terrain Slicing
showcase
voxel based world with the ability to show vertical slices of the terrain. The Discord thread contains some discussion about using prepass shaders with links to source code.
A separate Discord thread covers additional context around getting to this implementation.
Minecraft inspired
showcase
A wonderful looking Minecraft clone. Source code is available on GitHub.
This implementation has a chunk size of 32x32x32 and can handle 16 chunk render distance at smooth performance.
The discord thread includes a bunch of extra voxelly links:
100k enemies with bullet collisions
showcase
This kd-tree powered bullet hell demo can sustain 100k enemies with bullet collisions.
The discord thread also includes some interesting discussion about using different structures, like a spatial grid.
Townscaper-inspired irregular grid
showcase
Townscaper is a game in which you click to generate buildings. There are many aspects of Townscaper that make their way into other games: Wave Function Collapse is one, but the Procedural Irregular Grid is another.
The grid defines how buildings are built and results in a very organic looking collection. This is an implementation of that grid in Bevy, currently using gizmos.
Progress towards realtime path traced GI
showcase
GPU-driven realtime path-traced global illumination is a mouthful of words. That's what this example is. These examples over have to converge over some period of time, so be sure to check out the Discord thread to see the convergence speed. There's also some discussion of different Global Illumination approaches with mentions of ReSTIR, Radiance Cascades, and more.
bevy_mod_debugdump live playground
showcase
This live playground shows off the results of using bevy_mod_debugdump. If you've ever been curious about all the systems that run around inside of your Bevy app, this is a great place to check!
Contact Projective Decals
showcase
A talk on Path of Exile's rendering approaches mentioned something they called "Contact Parallax". This is an example implementing the technique inside of Bevy using the default renderer with the depth_prepass function.
The parallax mapping PR to Bevy and the tracking issue are also good reading for those interested in similar techniques.
Source is available on GitHub. and there's lots of great discussion in the Discord thread.
Particles!
showcase
bevy_firework is a CPU-driven, batch-rendered particle system, which can use bevy_xpbd colliders. This is in contrast to bevy_hanabi, which is GPU-based.
The collision uses xpbd's raycasts to detect collisions and runs a very primitive simulation to update velocities
