# piet-wgpu
The [wgpu] backend for the [Piet 2D graphics abstraction].
Features:
- [x] Rely on [raw-window-handle] which provides a common interface that [winit] can easily talk with.
- [x] Use [naga_oil] to combine and manipulate shader chunks.
- [ ] Framegraph based on bevy.
- [ ] Auto batching.
- [ ] Use SDF for rendering Circle, Ellipse, Rect and Text.
- [ ] Use GPU extruding for Line, Polyline and Path.
## Getting Started
```rust
// Create renderer based on wgpu.
let mut renderer = WgpuRenderer::new(
&window,
window.inner_size().width,
window.inner_size().height,
).await;
// Retrieve render context from renderer.
let mut ctx = Piet::new(&mut renderer);
// Use piet 2D API as usual.
let rect = Rect::new(0., 0., 100.0, 100.0);
let color = Color::rgb8(19, 86, 162);
ctx.fill(rect, &color);
// Release render context at last.
ctx.finish().unwrap();
std::mem::drop(ctx);
```
## Examples
### with_winit
It rely on [raw-window-handle] which provides a common interface that winit can easily talk with.
```bash
$ cargo run -p with_winit
```
### wasm
We use [cargo-run-wasm] instead of [trunk] serving the wasm example. It seems that trunk has [ISSUE](https://github.com/trunk-rs/trunk/issues/445) with cargo workspace in watching mode.
```bash
$ cargo run_wasm -p with_winit
```
## Development
Use [cargo-watch] like this:
```bash
$ cargo watch -x 'run_wasm -p with_winit'
```
## Other libs
- [vello] An experimental GPU compute-centric 2D renderer.
- [vger-rs] Use an uber shader to draw 2D SDF for Circle, Rect and Path.
- [piet-wgpu] Tessellation with [lyon].
- [rough-rs] Rust port of Rough.js.
