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. A particular focus is put on interactive methods using GPU-based techniques. Topics include:

History of Visualization Methods, from ancient wall paintings to GPU accelerated rendering
Data Sources

Simulation: basics of finite element discretization to GPU-based methods
Measurements: physical details of computed tomography to accelerated reconstruction

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)
Lighting

Local lighting models
GPU implementation

Environment Mapping
GPU Shadowing techniques

Shadow Volumes
Shadow Maps

Transparent Objects:

(depth) sorting with implementations on graphics hardware
Order independent transparency & depth peeling on GPUs

Physics based rendering

Radiometric quantities, rendering equation
Raytracing / path tracing
Radiosity
Irradiance volumes
Precomputed radiance transfer (PRT)
Ambient Occlusion with focus on GPU-based interactive methods

Special topics:

GPU friendly High quality terrain rendering & synthesis
Rendering of fur and hair
Scenegraph APIs
Acceleration structures and culling techniques
Human visual perception and high dynamic range imaging (HDRI)

Ziel dieses Projektes ist es seine Reihe von YouTube-Videos zu den Inhalten der Vorlesung Grundlegende Programmiertechniken (GPT) zu erstellen. Hierbei gilt es nicht nur Videoaufnahmen zu machen und diese digital Nachzubearbeiten, sondern zunächst ein Lehrkonzept für dieses Medium zu entwerfen, sowie geeignete Demosoftware zu erstellen. Angedacht ist es, mehrere konkurrierende Gruppen mit verschiedenen Konzepten zu bilden und die Ergebnisse gegenüberzustellen.

Wikipedia definiert die Computational Camera bzw. Computational photography folgendermaßen: „Computational photography or computational imaging refers to digital image capture and processing techniques that use digital computation instead of optical processes. Computational photography can improve the capabilities of a camera, or introduce features that were not possible at all with film based photography, or reduce the cost or size of camera elements“. Bei diesem Praxisprojekt handelt es sich um eine klassische Veranstaltung aus dem Bereich Computergrafik; wir wollen uns dabei mit verschiedenen Verfahren zur Generierung neuer Bilder und Videos aus Kameramaterial und computergestützten Berechnungen beschäftigen. Beispiele hierzu sind Zeitlupen- und Zeitraffer-Aufnahmen sowie HDR und multi-Fokus Bilder.

Abstract: 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.
