Scalable Seams for Gigapixel Panoramas
(The Eurographics Association, 2013)
Gigapixel panoramas are an increasingly popular digital image application. They are often created as a mosaic of smaller images composited into a larger single image. The mosaic acquisition can occur over many hours causing ...
Analysis of Cache Behavior and Performance of Different BVH Memory Layouts for Tracing Incoherent Rays
(The Eurographics Association, 2013)
With CPUs moving towards many-core architectures and GPUs becoming more general purpose architectures, path tracing can now be well parallelized on commodity hardware. While parallelization is trivial in theory, properties ...
Learning Kernels on Extended Reeb Graphs for 3D Shape Classification and Retrieval
(The Eurographics Association, 2013)
This paper addresses 3D shape classification and retrieval in terms of supervised selection of the most significant features in a space of attributed graphs encoding different shape characteristics. For this purpose, 3D ...
Evaluation of Surround-View and Self-Rotation in the OCTAVIS VR-System
(The Eurographics Association, 2013)
In this paper we evaluate spatial presence and orientation in the OCTAVIS system, a novel virtual reality platform aimed at training and rehabilitation of visual-spatial cognitive abilities. It consists of eight touch-screen ...
Toward Automated Façades Generation from Oblique Aerial Images
(The Eurographics Association, 2013)
In this paper we introduce an approach for automatic recognition and description of building façades from oblique aerial images. This approach does not use street-side images, like Google StreetView, but aerial images to ...
Visual Attention to Wayfinding Aids in Virtual Environments
(The Eurographics Association, 2013)
In an empirical evaluation, we examined participants' visual attention allocation to a dynamic wayfinding map in a complex simulation meant to educate medical practitioners in a hand hygiene protocol. Complex virtual ...
User-driven Feature Space Transformation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Interactive visualization systems for exploring and manipulating high-dimensional feature spaces have experienced a substantial progress in the last few years. State-of-art methods rely on solid mathematical and computational ...
Dynamic Maps for Exploring and Browsing Shapes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Large datasets of 3D objects require an intuitive way to browse and quickly explore shapes from the collection. We present a dynamic map of shapes where similar shapes are placed next to each other. Similarity between 3D ...
Spherical Visibility Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Many 3D scenes (e.g. generated from CAD data) are composed of a multitude of objects that are nested in each other. A showroom, for instance, may contain multiple cars and every car has a gearbox with many gearwheels located ...
On Quality Metrics of Bounding Volume Hierarchies
(ACM, 2013)
The surface area heuristic (SAH) is widely used as a predictor for ray tracing performance, and as a heuristic to guide the construction of spatial acceleration structures. We investigate how well SAH actually predicts ray ...
