Invitation to WSPS V

The Section of Mathematical and Information Sciences of the Association of Hungarian PhD and DLA Students anticipates your attendance at the 5th Winter School of PhD Students in Informatics and Mathematics, which will be held between:
2nd-4th March, 2018 at the Faculty of Informatics of University of Debrecen, Debrecen, Hungary.

The co-organisers and the sponsors of the event are John von Neumann Computer Society with the cooperation of the Regional Organisation of Hajdú-Bihar, and the Doctoral School of Informatics of University of Debrecen.

The aim of our winter school is dual:

  • improve the multidisciplinary scientific network of PhD students by inviting them to present their work in poster sessions and;
  • improve professional skills in an intensive workshop.

Each year, the workshop has a topic relevant for a wide audience. Internationally renowned scientists will give a number of in-depth lectures; these will be accompanied by seminar sessions where attendees will be able to explore topics in an interactive, hands-on way.
This year’s topic is computer graphics and modeling.

Lecture details

Getting started with 3D printing and modeling (Dr. Ildikó Papp)

Recently, 3D printing is one of the most dynamically developing technical activities.
It has an impact not only on the revolution of manufacturing technology but 3DP changes the dynamics of consumer culture by turning users into active creators from passive consumers.
The aim of our lecture and workshop is to introduce the most common 3DP technology (Fused Deposition Modeling) and to try a 3D modeling application considering the expectations of printable models.

GPU programming and architectures (Dr. Gábor Valasek)

GPUs have been in the forefront of high performance computing for over a decade and they are essential to many other applications. This lecture provides an overview of GPU architectures, their evolution from being a small collection of simple chips into components having the highest transistor count in a computer configuration. We briefly review how CPU pipelining affects efficient programming and how some of these ideas translate to GPU programming. Finally, we focus on modern GPU architectures and how their power can be utilized. During the practical session, we create simple applications that showcase not only the particular way we usually approach GPU programming, but also remind us of the difficulties of finite precision computing.

Monte Carlo Global Illumination Methods (Dr. László Szirmay-Kalos)

Physically plausible rendering can produce realistic images because computation process simulates the laws of physics accurately. To solve the light transport problem, a Fredholm type integral equation needs to be solved, or equivalently, high-dimensional dimensional integrals should be evaluated. To attack the curse of dimension, Monte Carlo or quasi-Monte Carlo quadrature rules are used. In this talk, we present the basic ideas of light transport and Monte Carlo integration, and develop a beatifully elegant and simple algorithm to compute the light transfer in scenes of diffuse and mirror like surfaces. This algorithm, called path tracing, is the core of production renderers used today to create computer generated images for movies. During the programming part of this presentation, a C++ framework should be extended with sampling and geometric calculation features to make the path tracing application complete.

VR – AR – MR — Realities and their Current Applications (Dr. Attila Tanács)

With the advent of modern smartphone platforms and PCs with high level graphics capabilities, we can observe a rise in applications of different types of “Realities”, including Virtual Reality (VR), Augmented Reality (AR), and more recently MR (Mixed Reality). In the lecture, an overview is given what each keyword means, what their main components are, what the necessary technical requirements are to be fulfilled. Further, some applications in the field of physiology is presented to help patients recover from different illnesses using so called “Serious Games”.
