## 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>
```
