During this prolonged cooperation with the IPP, we leveraged Blender to recycle the institute’s computational Wendelstein 7-X data from VMEC runs, and the complete web-service API, into a variety of accurate static images for publication, physically proximate animations, and intermediary software packages. Below are a few milestones worth mentioning.
INFO
The content shown below only displays project results dedicated to scientific communication.
Static Publication Material
Detailed renders of IPP’s W7-X and ASDEX Upgrade reactors, supplemented by a tokamak and planar-symmetric stellarator, were the initial project scope. Using simplified CAD models as reference, we constructed the reactor geometries through modelling and Python-based scripts. Vessel geometry, flux surfaces, and flow field indicators were derived from data obtained through designated web services. (most notably the Fortran VMEC and fieldline tracing engines)
Wendelstein Animations
Extending the geometries developed for static rendering, we pivoted to physically accurate animation as the project scope, overtaking the original project objectives in two months. The selection below represents a subset of the visualisation approaches and perspectives achieved in Blender. The products created herein were meant to serve as basis for downstream projects, for example the Eigenmode Simulation for ISHW2026 Córdoba or a cinematic short trailer of the reactor.
Software
A suite of utility scripts connecting the interfaces of VMEC, WebServices, and Blender were created during the project.
Arty Visuals
I used some of my personal Blender shaders to generate supplementary stylized visualizations. I was happy to see the renderings subsequently being integrated into institutional merchandise already during the 2025 open house event. Representative examples of cartoon and watercolor-themed renderings are shown below.
The unique experience with the cheerful IPP team led me to Driftwave Simulation, Eigenmode Simulation for ISHW2026 Córdoba, and Modelling a Magnetic Strain Model for Proxima Fusion
