Parametric L-systems

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.

Build

Install build dependencies:

• Install Rust
• Install wasm-pack

Then, within the project root directory, run

wasm-pack build --target web

Run

Install 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, or http-server)
• Navigate to the project's index.html using the browser with WebGPU enabled (e.g., localhost:8000 when using the Python HTTP server defaults, or localhost:8080 when using http-server's defaults)

User documentation

abop-fig-2-6.json	Honda's tree model.	Algorithmic beaty of plants, Fig. 2.6d
forest-abop-fig-2-6.json	All four trees shown in Fig. 2.6 in the book.	Algorithmic beaty of plants, Fig. 2.6
abop-fig-2-7.json	Aono and Kunii's tree model.	Algorithmic beaty of plants, Fig. 2.7d
forest-abop-fig-2-7.json	All four trees shown in Fig. 2.7 in the book.	Algorithmic beaty of plants, Fig. 2.7
tree-prusinkiewicz.json	A tree model as shown in Fig. 8g in the paper.	L-systems: from the Theory to Visual Models of Plants, Fig. 8g
growing-tree-prusinkiewicz.json	Four instances of the tree model as shown in Fig. 8g in the paper with different numbers of iterations.	L-systems: from the Theory to Visual Models of Plants, Fig. 8g
tree-prusinkiewicz-using-primitives.json	A tree adapted from Fig. 8 in the paper s.t. it has some leaves.	L-systems: from the Theory to Visual Models of Plants, Fig. 8
random-forest-prusinkiewicz-using-primitives.json	Nine trees adapted from Fig. 8 in the paper s.t. it they have some leaves and use some randomness in their productions, i.e., the trees will look different every time the scene is rendered.	L-systems: from the Theory to Visual Models of Plants, Fig. 8
tree-prusinkiewicz-with-floor.json	A tree model as shown in Fig. 8g in the paper and a large quad as floor.	L-systems: from the Theory to Visual Models of Plants, Fig. 8
tree-stochastic.json	A tree adapted from Fig. 8 in the paper s.t. it has uses some randomness in its productions.	L-systems: from the Theory to Visual Models of Plants, Fig. 8
