Abstract: The focus of this introductory course is on discussing efficient techniques to visually represent large-scale data sets from simulation and measurement. Starting with a brief introduction on the data generation processes the visualization pipeline, data structures, mapping techniques and special rendering techniques for scientific data will be discussed. Various examples will be given to outline the benefits of visualization techniques in practical applications.

Abstract: This lecture deals with the fundamentals of photorealistic and interactive image synthesis. In particular, we discuss techniques to achieve interactive frame rates for the realistic rendering of complex models and scenes. Selected graphics algorithms and their efficient implementation exploiting state-of-the-art graphics hardware through graphics APIs will be demonstrated. We focus on dedicated parts of the graphics pipeline and we review the functionality provided by consumer class graphics accelerators including programmable vertex-, geometry- and fragment shaders. In addition, we discuss the governing equations in physics based light transport and we demonstrate effective solution methods for the simulation of global illumination. Topics include:

Interactive image synthesis (i.e. rasterization and local illumination)

Graphics APIs & hardware
Fixed function & programmable graphics pipeline
Per-pixel lighting
Reflection and shadowing techniques
Order independent transparency / depth peeling
General-purpose computation on graphics hardware (GPGPU)

Physics based rendering (i.e. global illumination)

Radiometric quantities, rendering equation
Raytracing / path tracing
Radiosity
Irradiance volumes
Precomputed radiance transfer (PRT)
Ambient Occlusion

Other topics:

High quality terrain rendering & synthesis
Rendering of fur and hair
Scenegraphs
Acceleration structures and culling techniques
Human visual perception and high dynamic range imaging (HDRI)
REYES
Image compression techniques

Zusammenfassung: In diesem Praxisprojekt werden verschiedene Methoden aus dem Themengebiet der dreidimensionalen Bildsynthese in der Computergrafik bearbeitet. Im Wesentlichen werden die grundlegenden Verfahren Raytracing und Rasterisierung (mittels Grafik APIs) behandelt. In zwei Gruppen werden Sie jeweils eins der o.g. Verfahren kennenlernen und selbst ein Programm implementieren, welches dieses Verfahren realisiert. Nachdem jede Gruppe das grundlegende Rahmenwerk "ihres" Verfahrens implementiert hat, werden sich innerhalb der Gruppen kleine Teams bilden, die spezielle Techniken in das Rahmenwerk einbinden; derartige Techniken sind z.B. Beschleunigungsstrukturen, Spiegelungen, Brechungen, Schatten, Tiefenunschärfe, Bewegungsunschärfe, Toon-Shading, Stippling.

Lab Course (Forschungsprojekt): General Purpose Computation on GPUs

Kick-off Meeting: Mon. 16:00 — 17:00, April 7th, LE 305
Instructors: Thomas Fogal, Prof. Dr. J. Krüger
Course Language: English
Audience: Masters (Angewandte Informatik, Angewandte Kognitions- und Medienwissenschaften, International Studies in Engineering)

Achieving highly-performant code can be a difficult task. In the last decade, GPUs have become one of the most effective approaches to high-performance computation. However, effectively programming these architectures requires redesigning program components to take advantage of the highly data parallel architecture these platforms provide.

In this Forschungsprojekt, we will utilize these accelerator cards to achieve massive speedups for existing programs. Those whose research is hampered by the performance of their code are highly encouraged to participate. However, students with an interest in program performance are still encouraged to participate; topics will be assigned one.

Seminar: Recent Topics in Computer Graphics and Visualization

Registration & Kick-off Meeting: Thu. 14:00 — 16:00, April 10th, LF 125
Time & Place: Thu. 14:00 — 16:00, LF 125
Instructors: Prof. Dr. J. Krüger & team
Course Langugage: English or German
Audience: Bachelors & Masters (Angewandte Informatik, Angewandte Kognitions- und Medienwissenschaften, International Studies in Engineering)

Abstract: One of the goals of this seminar is to dive deeper into a few selected topics in computer graphics and visualization. Therefore, graduate students receive one or more recent publications from well known conferences such as IEEE VisWeek, ACM SIGGRAPH, and the EuroGraphics annual conference and explain the concepts laid out in these scientific publication in a scientific 30 to 40 minute talk. In addition to the scientific content in this seminar we will put special emphasis on the presentation. To improve the presentation skills of the participants we will start the seminar with simpe topics, record short talks from each participant, and analyze the presentation. Students then give a seminar talk on their chosen topic.
