A cross platform renderer using wgpu, written in rust. A proof of concept to compile and run on desktop, mobile and the web in one project.
| Platform | Compilation | BG Clear | Triangle |
|---|---|---|---|
| Desktop | ✔️ | ✔️ | ✔️ |
| Web | ✔️ | ✔️ | ✔️ |
| Android | ✔️ | ✔️ | ✔️ |
For desktop platforms nothing special aside from the standard rust toolchain is needed.
Install AndroidSDK and NDK and setup environment variables (ANDROID_SDK_ROOT and ANDROID_NDK_ROOT).
Install cargo-apk with cargo install cargo-apk.
Add desired android targets with rustup target add <triple>.
Install trunk with cargo install trunk
Add wasm target with rustup target add wasm32-unknown-unknown
Run cargo run. By default the desktop crate is build.
Run cargo apk run -p android-build optionally with the flag --target <triple> for explicit target selection.
Run cd bin/web/
Run trunk serve
Trunk is now serving app under http://localhost:8080

Change the limits in the device descriptor in core/src/lib.rs from wgpu::Limits::downlevel_webgl2_defaults() to wgpu::Limits::default().
Remove the webgl feature from core/Cargo.toml.
Set the --cfg=web_sys_unstable_apis rust flag.
This can be done by setting RUSTFLAGS=--cfg=web_sys_unstable_apis, or by creating a .cargo/config file with
[build]
rustflags = [
"--cfg=web_sys_unstable_apis"
]
