    Accurate representations of objects and light sources in a scenemodel are a crucial prerequisite for realistic image synthesis usingcomputer graphics techniques. This thesis presents techniques forthe efficient acquisition of real world objects and real world lightsources, as well as an assessment of the quality of the acquiredmodels.Making use of color management techniques, we setup an appearancereproduction pipeline that ensures best-possible reproduction oflocal light reflection with the available input and output devices.We introduce a hierarchical model for the subsurface light transport intranslucent objects, derive an acquisition methodology, and acquiremodels of several translucent objects that can be renderedinteractively. Since geometry models of real world objects areoften acquired using 3D range scanners, we also present a methodbased on the concept of modulation transfer functions to evaluatetheir accuracy.In order to illuminate a scene with realistic light sources, wepropose a method to acquire a model of the near-field emissionpattern of a light source with optical prefiltering. We apply thismethod to several light sources with different emissioncharacteristics and demonstrate the integration of the acquiredmodels into both, global illumination as well ashardware-accelerated rendering systems.EG Graphics Dissertation Onlin

    Massively parallel implementation of a multi-view stereo algorithm

    This thesis deals with the implementation of a multi-view stereo algorithm in a massively parallel way. The nature of multi-view stereo algorithms favors a parallel approach, as these algorithms operate on multiple images and in these images on multiple pixels. This work focuses on the matching optimization, of a region growing technique, in the multiview stereo approach by Goesele et al. which is the most computationally intensive step of the algorithm. Starting from a sparse 3D point cloud reconstructed using structure-from-motion methods, a nonlinear optimization is employed using a photoconsistency measure. Building upon an existing CPU implementation, an implementation for the matching optimization is written for NVIDIA graphics hardware which is essentially a massively parallel computing device. To access the hardware we make use of the Compute Unified Device Architecture (CUDA), a technology for General-Purpose computation on GPUs (GPGPU). Subsequently the GPU implementation is compared with the CPU version with regard to reconstruction quality and processing time. Furthermore different optimizations for exploiting the GPU architecture (and therefore reducing the processing time) are discussed and evaluated

    Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?

    In this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
