hypercubed

A (very WIP) Minecraft client implementation, written in Rust.

Currently connects to Minecraft: Java Edition 1.21.1 servers.

Main Goals

• Provide a more stutter-free experience than the vanilla Java client.
• Run on a wider range of hardware, including older devices the vanilla client no longer supports.
• In the future, provide some level of support for NeoForge mods.

Graphics Backends

• Vulkan - Requires Vulkan 1.2 with support for multi-draw indirect.
• wgpu - Not functional on WebGL2, but support is planned.
• OpenGL - Requires OpenGL 1.3 + GL_ARB_vertex_buffer_object + GL_ARB_vertex_program.
• Software - Based around Larrabee-style rasterisation, works best with wide SIMD instruction sets.

Variants of these backends with lower requirements are planned, as are variants which make use of newer hardware features.

Platforms

• winit - Intended to be the "default" backend for Windows, Linux and macOS.
• Linux KMS/DRM - Uses a mix of DRM, GBM, EGL, libseat, and libinput, and is intended for cases where running an X server or a Wayland compositor is impractical.
  Currently only supports the OpenGL graphics backend.
