GroIMP: A Beginners Tutorial Gerhard Buck-Sorlin, Institut Agro Rennes-Angers Installing GroIMP and making yourself familiar with the platform Installing the platform GroIMP on your computer is actually quite straightforward if you carefully follow the instructions below. GroIMP runs on Java, so first of all, make sure you have a recent version of Java installed. To check if you have Java installed on your machine you open the command prompt window (type cmd in the search window), then type “…

Installation Requirements GroIMP is written in Java, which means it should follow Java's WORA-principle (Write Once, Run Anywhere) and should run on every Java-capable platform. GroIMP has been tested successfully on Mac, Linux and Windows platforms.

Local illumination - Shader To set the optical properties of an object, in computer graphics the so-called local illumination model is used. It defines so-called shaders, that are define the amount of absorption, reflection and transmission and how the light rays are scattered. The values for absorption are obtained as the 'remaining radiation', i.e., the difference between reflectance and transmission, when we subtract the reflectance and transmission from the total of incoming radiation: Abso…

Post processing a QSM with RGG The combination of GroIMPs rule based graph manipulation and the QSM descriptors can be used to implements code based processing filters to improve a reconstructed tree. In this tutorial, we will create two simple example methods to improve a QSM model. These examples are designed to be simple and understandable rather than scientifically sound.$fchild$$fparent$

Mistake: Storing Nodes outside of the graph When developing a complex model in GroIMP, it happens that you want to “store” nodes in an “easy” to access data structure (list, array, map, ...), or as fields of other objects (create a module with its parent as field). Such kind of development practice are strongly discouraged, as they are both inefficient and prone to unexpected errors in the project. This tutorial will cover what type of issues this behavior can create, and propose different appr…

Improving leaf shape in the simple tomato model For improved leaf shape, we can define the leaf contour using a mathematical model. Below is the implementation of a simplified version; for the full equation, see Coussement et al. (2018). To add the leaf shape function into the model, open the
