A speedy and fairly-accurate Minecraft avatar renderer service.

A hosted version of NMSR is available here. It's provided on a best-effort basis, so please don't abuse it.

NMSR supports custom render parameters, player armour, armour trims, many render modes, native Ears mod support and Minecraft capes.

Since this project contains a few crates, here's a short explanation for each.

The star of the show. This is the service that does the actual rendering. If you're looking to self-host NMSR, this is the crate you're looking for.

Abstraction of a Minecraft player model. This serves as a base for the 3d model cubes and quads.

When compiled with the ears feature, it also provides Ears mod support.

The actual 3D rendering engine. This is where the magic happens. Implemented using wgpu-rs which allows for plugging many different rendering backends.

This is the (now legacy) UV map library. This used to do the actual "rendering" in previous versions. It requires pre-rendered images to be provided.

Currently, it uses version 2 of the UV map layout instead of the previous format.

For more information on the UV map layout, see here.

Crates in this directory are provided as-is and some may or may not be maintained.

Contains experiments that could be promoted to officially supported crates in the future.

This is the JNI library, which contains the native code for invoking the skin renderer from the JVM.

This is the current version of the UV map layout. It's an 8-bit RGBA image. It improves on the previous version by not being wasteful with the bits, at the cost of being more complex.

This is the previous version of the UV map layout. It's a 16-bit RGBA image. It's wasteful with the bits, but it's simple.
