Academic Projects

A List of Projects with academic value. I.e. projects that produced output in form of an academic publication.

Information Collage

TU Wien – Institute for Computer Graphics (Visualization Group)
Technical Report

Knowledge workers, such as scientists, journalists, or consultants, adaptively seek, gather, and consume information. These processes are often inefficient as existing user interfaces provide limited possibilities to combine information from various sources and different formats into a common knowledge representation. In this paper, we present the concept of an information collage (IC) -- a web browser extension combining manual spatial organization of gathered information fragments and automatic text analysis for interactive content exploration and expressive visual summaries. We used IC for case studies with knowledge workers from different domains and longer-term field studies over a period of one month. We identified three different ways how users collect and structure information and provide design recommendations how to support these observed usage strategies.

Inductive Rotation

TU Wien – Institute for Computer Graphics (Visualization Group)
Diploma Thesis

The so called "Inductive Rotation Method" is an approach to generate elaborate artistic patterns, developed by Kurt Hofstetter a Viennese artist. In the course of my diploma thesis I developed a new pattern creation framework for Hofstetter that contains algorithms which are based on similarities between numeral systems and the hierarchies of matrix multiplications that place each tile in an Inductive Rotation Pattern. The advantage of these algorithms is that they can be executed in parallel. I developed different compute shader implementations of these algorithms which run on the GPU in parallel and speed up pattern generation. The algorithms were brought together with new artistic tools that improve Hofstetters design process (for example a graphical tile editor) and resulted in the so called "Inductive Rotation Framework". The pattern-generation framework also provides an implementation of a tile-substitution method based on this scientific paper.

Symmetry Detection Project

TU Wien – Rendering Group
Internship

For my studies at the TU Wien I had to complete an extensive internship which included finding symmetries in mostly pre-segmented 3d models, implementing methods to generate Oriented Boudnig Boxes and other interesting topics (e.g. simple point grid generation, voronoi diagrams, etc.)
