## Overview

Myth is a cross-platform Rust 3D rendering engine. An application enters through the App/Engine runtime, loads or creates assets and a scene, then prepares frames for the renderer; the render graph schedules graphics and post-processing work for GPU output. The repository also provides animation, Python bindings, and an optional egui integration. The README documents the broader rendering capabilities; the sampled source confirms engine initialization, frame composition, asset loading, and selected Python operations, but not every internal pass connection.

Main entry points: [`crates/myth_app/src/engine.rs`](https://github.com/panxinmiao/myth/blob/main/crates/myth_app/src/engine.rs) (Engine coordinator), [`crates/myth_render/src/renderer.rs`](https://github.com/panxinmiao/myth/blob/main/crates/myth_render/src/renderer.rs) (Renderer), [`crates/myth_app/src/app.rs`](https://github.com/panxinmiao/myth/blob/main/crates/myth_app/src/app.rs) (App lifecycle), [`crates/myth_scene/src/scene.rs`](https://github.com/panxinmiao/myth/blob/main/crates/myth_scene/src/scene.rs) (Scene and camera)
