# scena documentation

`scena` is a Rust-native 3D scene-graph renderer for glTF/GLB model viewers,
CAD-style inspection, industrial visualization, browser/native applications,
and deterministic headless rendering.

- [docs.rs API reference]https://docs.rs/scena/latest/scena/: generated Rust API docs.
- [Getting started]getting-started.md: install, first scene, GLB loading, and output paths.
- [Easy scene setup]guides/easy-scene-setup.md: frame models, add studio lighting,
  add a matte grid floor, enable auto exposure, and connect authored anchors.
- [API overview]api.md: the main public types and how they fit together.
- [v1.5.0 release notes]release-notes/v1.5.0.md: expanded material presets, WebGL2 texture clamping, and smooth-metal browser IBL improvements.
- [v1.4.0 release notes]release-notes/v1.4.0.md: easy-use named primitives, bundled content, viewer ergonomics, `<scena-viewer>` element, and renderer-feature coverage.

## Examples

The `examples/` directory contains runnable Rust examples for first render,
primitive shapes, GLB model viewing, animation, picking, controls, instancing,
labels/helpers, browser canvas setup, native windows, and headless CI output.

Run one:

```bash
cargo run --example glb_model_viewer
```

Compile all public examples:

```bash
cargo check --examples
```
