A tiny hardware-accelerated pixel frame buffer. :crab:
|
|
|
|
## But why?
|
|
|
|
Rapidly prototype a simple 2D game, pixel-based animations, software renderers, or an emulator for your favorite platform. Then add shaders to simulate a CRT or just to spice it up with some nice VFX.
|
|
|
|
`pixels` is more than just a library to push pixels to a screen, but less than a full framework. You're in charge of managing a window environment, event loop, and input handling.
|
|
|
|
## Features
|
|
|
|
- Built on modern graphics APIs powered by [`wgpu`](https://crates.io/crates/wgpu): DirectX 12, Vulkan, Metal, OpenGL.
|
|
- Use your own custom shaders for special effects. (WIP)
|
|
- Hardware accelerated scaling on perfect pixel boundaries.
|
|
- Supports non-square pixel aspect ratios. (WIP)
|
|
|
|
## Examples
|
|
|
|
To demonstrate `pixels`, I've written a Space Invaders clone. The game logic can be found in the `simple-invaders` crate. The included example uses `simple-invaders` to rasterize the image, and `pixels` to display it. `winit` provides the windowing and event handling.
|
|
|
|
```bash
|
|
cargo run --release --example invaders
|
|
```
|
|
|
|
See the [example's README](./examples/invaders) for more information.

## Comparison with `minifb`
|
|
|
|
The [`minifb`](https://crates.io/crates/minifb) crate shares some similarities with `pixels`; it also allows rapid prototyping of 2D games and emulators. But it requires the use of its own window/GUI management, event loop, and input handling. One of the disadvantages with the `minifb` approach is the lack of hardware acceleration (except on macOS, which uses Metal but is not configurable). An advantage is that it relies on fewer dependencies.
