Experimental Design

This EVO visualizes model experimental setups (factorial pot experiments with growing plants) in an inhomogeneous environmental setting. Students can directly observe plant responses to changes in the experimental design and environmental factors. The response data can be exported for analysis with statistics packages.
Type: Modeling EVO 


Full EVOs are used in different courses at the Department of Environmental Systems Science at ETH Zurich. This section briefly characterizes sample EVOs of the current project.

Please note that Fundamentals, Modeling or Investigation EVOs are complex and specific teaching tools that are under constant development for academic courses and need a specific blended learning context. For that reason they are not directly accessible. However, at a later stage and upon request we may grant academic institutions access to our EVO approach for use in their own curriculum.

EVO components

EVO components are building blocks (template components) that can be modified and included in EVO projects to speed up development. As most EVO components include both 3D objects and python code snippets related to them, they are also ideal for learning EVO development.

EVO components (*.blend files) available for download on this website are offered under a Creative Commons licence (for details see the text infos included in the files).

Modeling of rosette leaves

In this video you learn how rosette leaves can be shaped from three different, interacting curves.

Below you find a number of tutorials on how Blender could be used in environmental visualization tasks in the broadest sense. We include both excerpts from our project-internal Blender training material and tutorials specifically created for this tutorial section.

Our background is in science, not in computer arts or multimedia training. We are also not long-term Blender professionals. So please take this into account when watching the tutorials and feel free to comment and make suggestions for improving the workflow shown!

Please note that we use a number of custom settings in the Blender user preferences:

  • selection with the left mouse button
  • emulate numpad (for laptops)
  • zoom to mouse position
  • rotate around selection
