Former Projects of Michael Wimmer

Wir sind Forscher an der TU Wien, die mittels Mathematik Bilder von 3D-Welten generieren wie in Videospielen oder Filmen. Technologischer Fortschritt ermöglicht es, die zugrundeliegende Geometrie solcher 3D-Welten nun auch online effizient mittels rein mathematischer Beschreibung zu erstellen. Generell ist das geplante Tool für alle, die sehen wollen, wie man schnell und einfach mit Hilfe von Mathematik Objekte oder Landschaften generieren kann.

Point clouds are a quintessential 3D geometry representation format, and often the first model obtained from reconstructive efforts, such as LIDAR scans. IVILPC aims for fast, authentic, interactive, and high-quality processing of such point-based data sets. Our project explores high-performance software rendering routines for various point-based primitives, such as point sprites, gaussian splats, surfels, and particle systems.

Photorealistic rendering, which is essential for many applications, involves evaluating complicated integrals. These integrals are predominantly approximated with a Monte Carlo method called path tracing. Unfortunately, this method generally requires many samples and therefore long computation times for noiseless images. Recently, so-called path-guiding techniques have been introduced, which gather knowledge about the integrands to facilitate sampling.

The main objective of this project is to demonstrate a novel approach to solve the problem of irradiation analysis in architectural design significantly faster than existing methods. This speed increase in turn enables new design workflows in architectural design. It will enable the designer to reduce the expected energy consumption of the designed building. More generally we will show that a difficult problem, previously viewed as a simulation problem, can be addressed utilizing the technology and techniques from computer graphics, specifically GPU accelerated rendering.

Dieses Projekt richtet sich an alle Menschen, die gerne etwas in der echten Welt einscannen und anderen Menschen als 3D-Modell zeigen wollen. Beispielsweise könnte ein Artist unterwegs eine interessante Skulptur finden und diese in ein Spiel einbauen oder als Miniatur ausdrucken. Raumplaner könnten z.B. eine Kreuzung einscannen, nach ihren Plänen verändern und diese damit besser kommunizieren.

The strong population growth and urbanization are increasing the global resources and energy consumption. The AEC (architecture, engineering and construction) industry is responsible for 60% of the extracted raw materials and generates 40% of the energy-related CO₂ emissions. In Austria, the AEC sector is responsible for 70% of total annual waste – facts that are underlining the importance of implementing recycling strategies.
