dawn client-server example

The goal of this demo is to create a minimal but functional Dawn-based WebGPU client and server with the following traits:

  • Client is like a web page that uses a high-level WebGPU API to create scenes and perform computations.
  • Client does not have any access to the host OS except for one duplex file descriptor connected to the server.
  • Server speaks with the OS, has an OS window which it draws to with dawn_native.
  • The client may live on a different computer than the server (i.e. connected over a network)

Build & run

  1. Run ./setup.sh which will fetch dawn, libev and build libev
  2. Run ./build.sh server client to build the client and server programs
  3. In two terminals, run out/debug/server and out/debug/client

Note: Tested on macOS 10.15 (x86_64) with clang 12

Watch-build-run mode is available with -w and -run to the build script:

./build.sh -w -run=./out/debug/server server

./build.sh -w -run=./out/debug/client client

Note: -w requires fswatch to be installed. On macOS you can get it from homebrew with brew install fswatch
