Tutorials

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

Crowd simulation visualization in Blender

For once, we refer to an external contribution to scientific visualization in Blender: In a workshop “Blender as research tool: from data to visualization” held by PhD student Sybren A. Stüvel from the University of Utrecht, it is shown how Blender can help in more realistic crowd simulation visualization. The workshop is focused on how to use Python to code the visualization.

Creating an object for 3D-printing

In this tutorial we create a landscape model such that it can be sent off for 3D-printing. This tutorial gives you just an overview over important aspects to be considered in the process and is meant to prepare you for the possibility of making EVOs physical.

For much more detailed instructions visit the 3D-printing with Blender video course by Dolf (Macouno) Veenvliet.

Dynamic painting

In this tutorial we create an animated ocean surface that puts down colour onto a canvas plane to produce a cumulative illustration of wave dynamics. We can vary this process by using colour with low opacity or using colour gradients.

Using particle systems for visualization of diffusion processes

In this video we create two particle systems within a container that is subdivided into two compartments by a semipermeable wall. Using different particle sizes we can visualize osmosis.

Making use of vertex weights for landscape models

In this two-part video you learn how to manipulate mesh vertex weights that influence how modifiers affect a landscape model and where materials you specified are applied.

Texturing a landscape section

In this video we create a surface texture for the mounds of a landscape section that grades into a different texture for the low-lying parts of the landscape.

Modeling of rosette leaves

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