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 ...
Fast Robust and Precise Shadow Algorithm for WebGL 1.0 Platform
(The Eurographics Association, 2015)
This paper presents fast and robust per-sample correct shadows for WebGL platform. The algorithm is based on silhouette shadow volumes and it rivals the standard shadow mapping performance. Our performance is usually ...
Evaluation of Transfer Function Methods in Direct Volume Rendering of the Blood Vessel Lumen
(The Eurographics Association, 2014)
Visualization of contrast enhanced blood vessels in CT angiography data presents a challenge due to varying concentration of the contrast agent. The purpose of this work is to evaluate the correctness (effectiveness) in ...
The Design Scope of Adaptive Storytelling in Virtual Museums
(The Eurographics Association, 2014)
This positioning paper seeks to evaluate how well the current state of interactive storytelling, content recommendation, and Linked Data can increase the efficaciousness of knowledge transfer in the context of cultural ...
A Haptics-enabled Simulator for Transperineal Ultrasound-Guided Biopsy
(The Eurographics Association, 2015)
We present the development of a transperineal prostate biopsy, with high fidelity haptic feedback. We describe our current prototype, which is using physical props and a Geomagic Touch. In addition, we discuss a method for ...
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 ...
From A Medial Surface To A Mesh
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Medial surfaces are well-known and interesting surface skeletons. As such, they can describe the topology and the geometry of a 3D closed object. The link between an object and its medial surface is also intuitively ...
Physical Space Requirements for Redirected Walking: How Size and Shape Affect Performance
(The Eurographics Association, 2015)
Redirected walking provides a compelling solution to explore large virtual environments in a natural way. However, research literature provides few guidelines regarding trade-offs involved in selecting size and layout for ...
Floor-based Audio-Haptic Virtual Collision Responses
(The Eurographics Association, 2012)
Virtual collisions are considered an important aspect of creating effective travel interactions for virtual environments; yet, they are not yet well understood. We introduce a new floor based audio-haptic interface for ...
