Systems allowing the creation and manipulation of graphical information (so-called Graphic Editors) have become essential in various fields of applications. At the same time the typical user of such a system has changed. Not computer experts, but designers, secretaries, technicians, teachers etc. are today's typical users of computer graphics, mostly on microcomputers. Obviously it would be desirable to have a common concept of graphics editing covering many applications. The purpose of this paper is a...

Smooth Transitioning Between two Walking Metaphors for Virtual Reality Applications

Isadora Salvetti, Alex Rios & Pelechano Nuria
Virtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the dimensions of the virtual environment match those of the real world. The problem of most navigation techniques is that they produce motion sickness because the optical flow observed does not match the vestibular and proprioceptive information that appears...

Semi-Automatic Vessel Boundary Detection in Cardiac 4D PC-MRI Data Using FTLE fields

Benjamin Behrendt, Benjamin Köhler, Daniel Gräfe, Matthias Grothoff, Matthias Gutberlet & Bernhard Preim
Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) is a method to non-invasively acquire in-vivo blood flow, e.g. in the aorta. It produces three-dimensional, time-resolved datasets containing both flow speed and direction for each voxel. In order to perform qualitative and quantitative data analysis on these datasets, a vessel segmentation is often required. These segmentations are mostly performed manually or semi-automatically, based on three-dimensional intensity images containing the maximal flow speed over all time steps. To...

Progressive Dimension-Independent Boolean Operations

A. Paoluzzi, V. Pascucci & G. Scorzelli
This paper introduces a new progressive multi-resolution approach for representating and processing polyhedral objects of any dimension. Our representation, a variant of BSP trees [Nay90] combined with the Split scheme introduced in [BP96], allows progressive streaming and rendering of solid models at multiple levels of detail (LOD). Boolean set operations are computed progressively by reading in input a stream of incremental refinements of the operands. Each refinement of the input is mapped immediately to a...

Geometry Videos: A New Representation for 3D Animations

Hector M. Briceño, Pedro V. Sander, Leonard McMillan, Steven Gortler & Hugues Hoppe
We present the 'Geometry Video', a new data structure to encode animated meshes. Being able to encode animated meshes in a generic source-independent format allows people to share experiences. Changing the viewpoint allows more interaction than the fixed view supported by 2D video. Geometry videos are based on the 'Geometry Image' mesh representation introduced by Gu et al. 4. Our novel data structure provides a way to treat an animated mesh as a video sequence...

OphthalVis - Making Data Analytics of Optical Coherence Tomography Reproducible

Paul Rosenthal, Marc Ritter, Danny Kowerko & Christian Heine
In this paper, we discuss the issues of the current state of the art in optical coherence tomography with respect to reproducibility. We present our findings about the internal computations and data storage methods of the currently used devices. The gained knowledge was used to implement a tool to read a variety of OCT file formats and reproduce the visualizations used in daily clinical routine.

Quasi-3D cell-based Animation

M. Qi & P.J. Willis
We present a method for image compositing and rendering using 2D geometric shapes or raster images as input primitives, disposed in a 3D environment around which the camera can move. An animation system has been implemented which calculates camera and scene information to render the frames. The key features of this quasi- 3D system are described. Two animations generated by the system are given as examples.

Browsing Spatial Photography for Dissemination of Cultural Heritage Research Results using Augmented Models

Florian Niebling, Jonas Bruschke & Marc Erich Latoschik
Both digital and physical 3D models of buildings as well as historical photographs of architecture are used for a wide range of needs, from research in humanities and information technologies, museum contexts and library studies, to touristic applications. Spatially oriented photographs play an important role in visualizing and browsing contemporary as well as historical architecture, starting with the ground-breaking Photo Tourism project [SSS06]. We present a technique to combine physical, 3D-printed models of buildings with...

Stipple Removal in Extreme-tone Regions

Rosa Azami, Lars Doyle & David Mould
Conventional tone-preserving stippling struggles with extreme-tone regions. Dark regions require immense quantities of stipples, while light regions become littered with stipples that are distracting and, because of their low density, cannot communicate any image features that may be present. We propose a method to address these problems, augmenting existing stippling methods. We will cover dark regions with solid polygons rather than stipples; in light areas, we both preprocess the image to prevent stipple placement in...

HT-based Recognition of Patterns on 3D Shapes Using a Dictionary of Mathematical Curves

Chiara Romanengo, Silvia Biasotti & Bianca Falcidieno
Characteristic curves play a fundamental role in the way a shape is perceived and illustrated. To address the curve recognition problem on surfaces, we adopt a generalisation of the Hough Transform (HT) which is able to deal with mathematical curves. In particular, we extend the set of curves so far adopted for curve recognition with the HT and propose a new dictionary of curves to be selected as templates. In addition, we introduce rules of...
