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 using GPU accelerated techniques. 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
    • Graphics APIs & hardware, OpenGL, DirectX, Vulkan and CUDA
    • Fixed function & programmable graphics pipeline
    • Introduction to General-purpose computation on graphics hardware (GPGPU)

Lab Course (Forschungsprojekt): Der Traum vom Fliegen - in VR

Kick-off & Registration Meeting: 9. April, 14:00 s.t., LE 335
Instructor: A. Krekhov, S. Cmentowski & Prof. Dr. J. Krüger
Course Language: German
Audience: Master

In diesem Forschungsprojekt setzen wir uns damit auseinander, wie man sich fliegend durch VR-Welten fortbewegen kann. Wir erarbeiten verschiedene neuartige Lösungsansätze (z.B. Flügelschlag durch Armbewegung) und validieren diese anschließend im Rahmen einer Studie. Vorwissen im VR-Bereich ist nicht erforderlich, allerdings setzen wir Unit3D-Kenntnisse für die Umsetzung der Flugmechanismen voraus. Ferner sind Grundkenntnisse im Bereich Studiendesign empfohlen.
