3D Architectural Modeling: Efficient RANSAC for n-gonal Primitive Fitting
(The Eurographics Association, 2015)We present a modeling approach to automatically fit 3D primitives to point clouds in order to generate a CAD like model. For detailed modeling we propose a new n-gonal 3D primitive and a novel RANSAC based fitting approach. ... -
3D Fabrication of 2D Mechanisms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)The success of physics sandbox applications and physics-based puzzle games is a strong indication that casual users and hobbyists enjoy designing mechanisms, for educational or entertainment purposes. In these applications, ... -
3D Video: from Capture to Interactive Display
(The Eurographics Association, 2015)While 3D vision and 3D/4D imaging has existed for many years, the use of 3D cameras and video-based modeling by the film industry and recent access to cheap contactless control devices has induced an explosion of interest ... -
4D Mesh Reconstruction from Time-Varying Voxelized Geometry through ARAP Tracking
(The Eurographics Association, 2015)We present a method to derive a time-evolving triangle mesh representation from a sequence of binary volumetric data representing an arbitrary motion. Multi-view reconstruction studios use a multiple camera set to turn an ... -
Adaptable Anatomical Models for Realistic Bone Motion Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a system to reconstruct subject-specific anatomy models while relying only on exterior measurements represented by point clouds. Our model combines geometry, kinematics, and skin deformations (skinning). This ... -
Adapting the Twelve Principles of Classic Animation to Lectures
(The Eurographics Association, 2015)This paper borrows from the fields of classic animation and 3D animation and adapts the fundamental principles of these subjects to the lecturing context. An analogy is drawn between an animator and a lecturer due to their ... -
Adaptive LightSlice for Virtual Ray Lights
(The Eurographics Association, 2015)We speed up the rendering of participating media with Virtual Ray Lights (VRLs) by clustering them in a preprocessing step. A subset of representative VRLs is then sampled from the clustering, which is used for the final ... -
Approximating Free-form Geometry with Height Fields for Manufacturing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We consider the problem of manufacturing free-form geometry with classical manufacturing techniques, such as mold casting or 3-axis milling. We determine a set of constraints that are necessary for manufacturability and ... -
Approximating the Generalized Voronoi Diagram of Closely Spaced Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an algorithm to compute an approximation of the generalized Voronoi diagram (GVD) on arbitrary collections of 2D or 3D geometric objects. In particular, we focus on datasets with closely spaced objects; GVD ... -
Augmented Reality as a Tool to Deliver e-Learning based Blended Content in and out of the Class-room
(The Eurographics Association, 2015)In this paper, we present a mobile Augmented Reality application that can be used for undergraduate anatomical education. It can be used in and out of the classroom. In the classroom, the application can track and augment ... -
Augmenting Design Curriculum with Location-Aware Technologies
(The Eurographics Association, 2015)This paper discusses ways in which emerging interactive augmented reality (AR) technologies are being adopted by designers and extended into areas of tourism, education, entertainment and commerce. It discusses, in detail, ... -
Big City 3D Visual Analysis
(The Eurographics Association, 2015)A big city visual analysis platform based on Web Virtual Reality Geographical Information System (WEBVRGIS) is presented. Extensive model editing functions and spatial analysis functions are available, including terrain ... -
Biologically-Inspired Visual Simulation of Insect Swarms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Representing the majority of living animals, insects are the most ubiquitous biological organisms on Earth. Being able to simulate insect swarms could enhance visual realism of various graphical applications. However, the ... -
A Biophysically-Based Model of the Optical Properties of Skin Aging
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper presents a time-varying, multi-layered biophysically-based model of the optical properties of human skin, suitable for simulating appearance changes due to aging. We have identified the key aspects that cause ... -
CHC+RT: Coherent Hierarchical Culling for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new technique for in-core and out-of-core GPU ray tracing using a generalization of hierarchical occlusion culling in the style of the CHC++ method. Our method exploits the rasterization pipeline and hardware ... -
Color Sequence Preserving Decolorization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many visualization techniques use images containing meaningful color sequences. If such images are converted to grayscale, the sequence is often distorted, compromising the information in the image.We preserve the significance ... -
Combining Human Visual System Models for Geographic Gaze Contingent Displays
(The Eurographics Association, 2015)We present a gaze-contingent display (GCD) in which we combine multiple models of the human visual system (HVS) to manage the visual level of detail (LOD). GCDs respond to the viewer's gaze in real time, rendering a ... -
