Christiaan Spieker, PhD student at the Computational Science Lab, together with colleagues at the Visualisation Lab won the first ‘Student Visualisation Competition” held at the “CompBioMed 2023″ conference in Munich. The image entitled ‘Cinematic punctured vessel blood flow simulation visualisation” uses simulation data produced by the Computational Science Lab. The image was produced by a joint effort from Christian Spieker, Joey van der Kaaij, David de Kanter, Robert Belleman, Gábor Závodszky, and Alfons Hoekstra.

The creation process of the image begins with raw blood cell simulation data in XMF and HD5 format, which is converted into mesh data (the X3D format) with the help of Paraview. The meshes are imported into Blender. Meanwhile, a cylinder is modeled in ZBrush to represent the blood vessel and further textured in Adobe Substance Painter to put a realistic-looking skin on the model. This textured model is subsequently imported into Blender alongside the blood cell models.

Once the components are in Blender, the scene is rendered using the Cycles rendering engine to produce an image of the blood vessel and blood cells. The final stage involves the import of the rendered image into Adobe Photoshop, where an appropriate background environment for the blood vessel is created, and some touchups are made to improve the overall visual appeal of the image. This comprehensive pipeline blends raw data conversion, 3D modeling, texturing, rendering, and post-processing to generate a detailed and realistic image of blood cells in a blood vessel.

The Institute for Logic, Language and Computation (ILLC) and the Informatics Institute (IvI) are thrilled to announce the acquisition of a state-of-the-art motion capture system, which includes a cutting-edge face capture system. This advanced technology will be a valuable addition to the facilities of both institutes, enabling researchers to capture high-quality motion data and facial expressions for a wide range of applications.

The system has been installed in the Visualisation Lab on the ground floor of Lab42. Rob Belleman, manager of the Visualisation Lab, states: “This motion capture system is a significant addition to the facilities in the lab and will allow us to take our research and education to the next level. With its advanced capabilities, we can capture even the subtlest of movements, which will be invaluable for a wide range of projects.”

One of the primary beneficiaries of this new system is SignLab Amsterdam, a research group that studies sign language and its impact on communication. SignLab Amsterdam is a collaboration between researchers from ILLC and IvI, as well as sign language linguists at the Faculty of Humanities. Floris Roelofsen, founding co-director of the lab, says: “With the motion capture system’s precision and accuracy, SignLab researchers will be able to better understand and analyze the intricacies of sign language, enhancing their work on sign language recognition and translation.”

The new motion capture system in the Visualisation Lab is a testament to our commitment to providing cutting-edge resources to researchers, faculty, and students at Lab42. We look forward to seeing the innovative work that will be produced using this technology.

On October 26, the Visualisation Lab of the University of Amsterdam, together with SURF and the UvA 4D Research Lab, hosts an XR on Tour event.

Students, researchers and staff of the UvA interested in Virtual Reality, Augmented Reality and other forms of Extended Reality (XR) are welcome to join the walk-in demos and try out technologies for themselves. The UvA Visualisation Lab will demonstrate XR applications for education & research, while SURF will demonstrate the current capabilities of XR, AR & VR technologies.

We hope you will get inspired by the possibilities of virtual and augmented reality, experience the demos yourself and grow your network!

See this page for more information on XR on Tour.

Computational Science student Yazhou Zeng defended his master thesis August 3rd, 2020, on “Quantitative morphometrics of scleractinian corals”. Yazhou developed a data analysis pipeline for the quantitative analysis of CT scans of corals.

Software Engineering student Sandro Massa successfully defended his master thesis on July 25th 2022. Sandro worked on an “Interactive Visualization Pipeline Construction Environment for Virtual Reality Visualizations”, which included a software interface that allows one to use the functionality of the Visualisation Toolkit (VTK) in the Unity development engine. Congratulations Sandro!

Iris Reitsma successfully defended her Computational Science master thesis today, June 30th. The title of her thesis is “Simulation of Tree Root Growth in a 3D Model of Amsterdam”, and reports on the work she did together with the Amsterdam municipality on modeling the growth of root tree systems and predicting their interaction with the infrastructure in Amsterdam. The result of her work is included in 3D Amsterdam.
