An implementation of parametric L-systems for the Fractals course at TU Wien.
On Windows, MacOS, and ChromeOS, you can check it out directly at jolifantobambla.github.io/parametric-l-systems in Google Chrome (from version 94 to 114) thanks to the WebGPU origin trial.
Install build dependencies:
Then, within the project root directory, run
wasm-pack build --target webInstall requirements:
- Install a browser that supports WebGPU, and if necessary, enable WebGPU in the browser (e.g., on Linux: Chromium with flags
--enable-vulkan --enable-unsafe-webgpu). - Install a HTTP server (e.g., Python 3 and its http.server module, or the NodeJS module http-server)
Then, within the project root directory
- Serve the project using an HTTP server (e.g.,
python -m http.server, orhttp-server) - Navigate to the project's
index.htmlusing the browser with WebGPU enabled (e.g.,localhost:8000when using the Python HTTP server defaults, orlocalhost:8080when usinghttp-server's defaults)
The documentation can be found here, or directly under the Documentation tab on the website (either served locally, or at jolifantobambla.github.io/parametric-l-systems)
