Growth models step by step
In this tutorial we will create a growth model for a crown architecture. The model considers only the branch structure, without leaves, to provide an easy entry point. It may be helpful to understand the basic RGG code structure first, a tutorial is provided $l$text/html2025-12-12T11:13:26+00:00Anonymous (anonymous@undisclosed.example.com)A simple tomato plant model

A simple tomato plant model
In this tutorial we will create a simple model of a tomato plant architecture.
Preliminary steps
We start a new project by opening a new RGG template model (File -> New -> RGG Project).
The simple model that we are going to create will have the following structure:text/html2026-01-05T11:58:31+00:00Anonymous (anonymous@undisclosed.example.com)From light interception to photosynthesis

From light interception to photosynthesis
Should this be a class ?
Introducing light interception of leaves
Open the file [Light.gsz]. This is a simple model of a plant that will grow (produce new leaves and internodes) and branch, while each leaf intercepts light from a lamp hanging over it.
One of the first things that come to mind when thinking about plant functions is, of course, photosynthesis. In order for the plant to do photosynthesis, it needs energy, water and CO
