- Use texture buffers instead of instanced arrays - Fixes issues with instance layouts using int elements - Fixes attribute binding hardware limitations - Create one texture for the entire instancing engine and bind each instancer's vbo when it's time to draw - Generate glsl to fetch FlwInstances from a usamplerBuffer according to the instance layout - Use RGBA32UI to get the most data from each texel fetch - Align instance stride to 16 to avoid complexity in unpacking |

Flywheel
A modern engine for modded Minecraft.
About
The goal of this project is to provide tools for mod developers so they no longer have to worry about performance, or limitations of Minecraft's archaic rendering engine. That said, this is primarily an outlet for me to have fun with graphics programming.
Instancing
Flywheel provides an alternate, unified path for entity and tile entity rendering that takes advantage of GPU instancing. In doing so, Flywheel gives the developer the flexibility to define their own vertex and instance formats, and write custom shaders to ingest that data.
Shaders
To accomodate the developer and leave more in the hands of the engine, Flywheel provides a custom shader loading and templating system to hide the details of the CPU/GPU interface. This system is a work in progress. There will be breaking changes, and I make no guarantees of backwards compatibility.
Plans
- Vanilla performance improvements
- Compute shader particles
- Deferred rendering
- Different renderers for differently aged hardware
Getting Started (For Developers)
Add the following repo and dependency to your build.gradle:
repositories {
maven {
name "tterrag maven"
url "https://maven.tterrag.com/"
}
}
dependencies {
implementation fg.deobf("com.jozufozu.flywheel:Flywheel-Forge:${flywheel_version}")
}
${flywheel_version} gets replaced by the version of Flywheel you want to use, eg. 1.18-0.3.0.3
For a list of available Flywheel versions, you can check the maven.
If you aren't using mixed mappings (or just want to be safe), add the following properties to your run configurations:
property 'mixin.env.remapRefMap', 'true'
property 'mixin.env.refMapRemappingFile', "${projectDir}/build/createSrgToMcp/output.srg"
This ensures that Flywheel's mixins get properly loaded in your dev env.
