Eidolon

简体中文

Eidolon is a Minecraft skin renderer written in Rust. It can render a 3D model of a player skin to an image, or preview it in a window.

Features

• Load and render Minecraft player models
• Texture mapping support
• 3D rendering with wgpu (Vulkan / Metal / DX12)
• Save rendering result as PNG or WebP
• Configurable camera, poses, and output size
• Headless off-screen rendering and windowed preview
• Cross-platform: Windows, macOS, Linux

Quick Start

Prerequisites

• Rust (latest stable recommended)
• A GPU with Vulkan, Metal, or DX12 support
• A working wgpu backend. On headless systems this may require a configured software backend such as OSMesa, depending on the platform.

Build

cargo build

Render an Image

# Minimal — all defaults (classic arms, stand pose, 800×600 PNG)
cargo run -- render resources/bingling_sama.png

# Slim arms, wave pose, WebP output
cargo run -- render resources/bingling_sama.png out.webp --slim --posture wave

# Custom camera angle and zoom
cargo run -- render resources/bingling_sama.png --cam-yaw 210 --cam-zoom 1.5 --width 1024 --height 1024

Preview in a Window

cargo run -- preview resources/bingling_sama.png
cargo run -- preview resources/bingling_sama.png --slim --cam-zoom 2.0

More CLI options are documented in docs/cli.md.

Library Usage

Eidolon can be used as a Rust library. Minimal example:

use eidolon::{
    camera::Camera,
    character::{Character, SkinType},
    renderer::{OutputFormat, Renderer},
};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let renderer = Renderer::new()?;

    let character = Character::new();
    let skin = renderer.load_texture("skin.png")?;
    let camera = Camera::new();

    renderer.render_to_image(
        &character,
        &skin,
        &camera,
        "output.png",
        (800, 600),
        OutputFormat::Png,
    )?;

    Ok(())
}
