On 15th of March, 2018, Jan-Willem van Velzen successfully defended his master thesis titled “Texture-based Rendering of Vector-based Shapes”. In his work he presents an approach to store vector-based shapes into discrete raster-based textures, optimized for parallel rendering. He also discusses the implementation of both the serialization and deserialization steps, as well as rendering regular vector shapes with a comparable quality.
We congratulate Jan-Williem with his work and defense and wish him all the best for the future!
On the 10th of October, Lennaert van den Brink successfully defended his thesis “HiveArcs – visualizing genome co-expression data“. In his work, he introduced HiveArcs, an interactive online visual analysis for genome co-expression data. HiveArcs visualizes modules using arc diagrams on radially placed axes. Using this lay-out accommodates display of per-gene tracks of additional information as well as relationships between modules. This allows for quick and intuitive comparison between modules as well as in depth analysis of a single module.
We would like to congratulate Lennaert with his work and defense and wish him all the best for the future!
Korijn van Golen and Matthijs Neven successfully defended their theses in our group recently.
On Tuesday, the 8th of July, Korijn defended his thesis “Landmark Influence Visualization in Active Shape Models”. In his work he introduced a novel landmark influence visualization that improves the usability of Active Shape Models. Landmark influence is defined as the change the model fit will undergo if a landmark is removed. The landmark influence is visualized using disk glyphs around landmarks. A region-of-interest filter can be used to inspect influence on local regions. Distance maps and animations visualize how the shape will change.
On Friday, the 22nd of August, Matthijs defended his thesis “Interactive Remote Rendering”. In his work, he present an interactive remote volume-rendering system that tries to bridge the gap between complex medical volume data and the patient. The user can easily upload their own data, which they receive from the clinician after a scan, which they can then visualize. The application does not require any medical or volume visualization background, and can run from any device with a working internet connection and an internet browser.
We’d like to congratulate Korijn and Matthijs with their Master of Science titles!
TU Delta has just posted a nice story on the new games that our undergrad students developed during the Games Project 2014. The article includes a list of YouTube links to their awesome trailers: check them out!
Casper van Leeuwen successfully defended his thesis ‘Spatial-temporal pathline clustering based on FTLE fields‘ in our group on the 14th of May.
In his work, Casper worked with cardiac flow acquisition data consisting of 3D blood flow of the heart featuring 4D vector fields. These 4D vector fields of the heart are used in clinical research to gain insight in the flow patterns within the heart which in turn can be used to gain a better understanding of the pathogenesis of cardiovascular diseases. He implemented a visualization technique called Spatial-temporal Clustering based on Finite Time Lyapunov Exponents, that aims to circumvent the challenges posed by the structural complexity of the flow and give a concise and insightful representation of the blood flow patterns within the heart. Aside from the main visualization technique this works also introduces a novel probing technique that highlights the base principles of the FTLE fields to provide the user with a better understanding of how a FTLE field works.
We would like to congratulate Casper with his achievement and new title and wish him all the best for the future!
Yesterday, at the open days for the potential new computer science bachelor students, the CGV group presented several gametech-related student projects. Here are some pictures from the TU Delft Computer Science facebook page:
On Monday, there will be another chance to see these projects and many more at the second day of the open days.
