## Structure
For the simplest examples without using any helping code (see `framework.rs` here), check out:
- `hello ` for printing adapter information
- `hello-triangle` for graphics and presentation
- `hello-compute` for pure computing
Notably, `capture` example shows rendering without a surface/window. It reads back the contents and saves them to a file.
All the examples use [WGSL](https://gpuweb.github.io/gpuweb/wgsl.html) shaders unless specified otherwise.
All framework-based examples render to the window and are reftested against the screenshot in the directory.

## Hacking
You can record an API trace any of the framework-based examples by starting them as:
```sh
mkdir -p trace && WGPU_TRACE=trace cargo run --features trace --example <example-name>
```
