Faculty Electrical Engineering, Mathematics and Computer Science

The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) is known worldwide for its high academic quality and the social relevance of its research programmes. The faculty’s excellent facilities accentuate its international position in teaching and research. Within this interdisciplinary and international setting the faculty employs more than 1100 employees, including about 400 graduate students and about 2100 students. Together they work on a broad range of technical innovations in the fields of sustainable energy, telecommunications, microelectronics, embedded systems, computer and software engineering, interactive multimedia and applied mathematics.

The Department of Intelligent Systems (INSY) conceptualises computer science methodologies to sense, abstract, learn, reason, elicit and adapt data and their meaning in ways that respect human values in order to increase human effectiveness, well-being and social innovation. At the heart of the department is therefore research and teaching in computer science theory, algorithms and solutions for information processing systems that support humans (e.g. robotics), new products (e.g. Internet services), and science (e.g. biology).   

The Computer Graphics and Visualization Group has a strong research record and is known for its expertise in visual analytics, visualization in general, modelling, game technology, and rendering. Besides these major topics, interaction techniques, virtual/augmented reality, vision, perception, computational photography, and simulations play an important role. The group also participates strongly in the Delft Research Initiatives “Environment” and “Health”, thus aiming to find solutions for tomorrow’s problems. It maintains a strong network of partners worldwide from academia, medical centres and industry.    


Functie omschrijving

Controlling light in an environment is a difficult task, since many aspects such as materials, light sources, and geometry have to be considered. Thus, achieving a particular light distribution is not trivial, but necessary in many contexts (architecture, greenhouses,…).

The candidate will be embedded in a group with several PhD students and postdocs active in the area of rendering and the project itself is linked to a multi-disciplinary consortium with the goal of developing efficient lighting computations for green-house environments. The main objective of our work is to produce novel, interactive solutions for high-performance light transport computations. We will investigate practical aspects, such as efficient ray-tracing solutions, with a controllable tradeoff between accuracy and performance. To this extent, we will address the problem from various angles. First, we opt for new hierarchical approaches and alternative representations for visibility and transport queries. We recently presented compact and compressed scene representations and intend to adapt their use to light transport. Here, we will also focus on alternative representations of material properties, which are a key ingredient for an efficient and accurate multi-scale light transport. Secondly, we intend to explore efficient use of multi-core environments and progressive rendering solutions. The candidate will have access to a dedicated multi-GPU compute cluster environment. Third, we want to build upon recent signal reconstruction techniques to minimize the computational cost of the overall process.
