An Endoscope Interface for Immersive Virtual Reality
(The Eurographics Association, 2020)This is a work in progress paper that describes a novel endoscope interface designed for use in an immersive virtual reality surgical simulator. We use an affordable off the shelf head mounted display to recreate the ... -
End‐to‐End Compressed Meshlet Rendering
(© 2024 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2024)In this paper, we study rendering of end‐to‐end compressed triangle meshes using modern GPU techniques, in particular, mesh shaders. Our approach allows us to keep unstructured triangle meshes in GPU memory in compressed ... -
Energetically Consistent Invertible Elasticity
(The Eurographics Association, 2012)We provide a smooth extension of arbitrary isotropic hyperelastic energy density functions to inverted configurations. This extension is designed to improve robustness for elasticity simulations with ex- tremely large ... -
An Energy and Bandwidth Efficient Ray Tracing Architecture
(ACM, 2013)We propose two hardware mechanisms to decrease energy consumption on massively parallel graphics processors for ray tracing while keeping performance high. First, we use a streaming data model and configure part of the L2 ... -
Energy Aware Color Sets
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a design technique for colors with the purpose of lowering the energy consumption of the display device. Our approach is based on a screen space variant energy model. The result of our design is a set of ... -
Energy Duality Methods for Piecewise Bezier Curve Construction
(Blackwell Science Ltd and the Eurographics Association, 1996)Piecewise Bezier Curves are constructed using a minimization principle. Ck and GCk continuity is imposed by linear constraints. The corresponding quadratic programming with linear constraints problem is introduced and ... -
Energy Stability and Fracture for Frame Rate Rigid Body Simulations
(ACM SIGGRAPH / Eurographics Association, 2009)Our goal is to design robust algorithms that can be used for building real-time systems, but rather than starting with overly simplistic particle-based methods, we aim to modify higher-end visual effects algorithms. A major ... -
An Energy-Based Approach for Contact Force Computation
(Blackwell Science Ltd and the Eurographics Association, 1996)A new approach for computing resting contact forces between solids is presented, which handles both static and sliding friction, while avoiding the problems arising from previous approaches. Each iteration provides values ... -
Energy-Based Image Deformation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a general approach to shape deformation based on energy minimization, and applications of this approach to the problems of image resizing and 2D shape deformation. Our deformation energy generalizes that found ... -
An Energy-Conserving Hair Reflectance Model
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a reflectance model for dielectric cylinders with rough surfaces such as human hair fibers. Our model is energy conserving and can evaluate arbitrarily many orders of internal reflection. Accounting for compression ... -
An Energy-Conserving Hair Shading Model Based on Neural Style Transfer
(The Eurographics Association, 2020)We present a novel approach for shading photorealistic hair animation, which is the essential visual element for depicting realistic hairs of virtual characters. Our model is able to shade high-quality hairs quickly by ... -
Energy-efficient mid-term strategies for collision avoidance in crowd simulation
(ACM Siggraph, 2015)When navigating in crowds, humans are able to move efficiently between people. They look ahead to know which path would reduce the complexity of their interactions with others. Current navigation systems for virtual agents ... -
Energy-scale Aware Feature Extraction for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In the visualization of flow simulation data, feature detectors often tend to result in overly rich response, making some sort of filtering or simplification necessary to convey meaningful images. In this paper we present ... -
Enforcing Energy Preservation in Microfacet Models
(The Eurographics Association, 2022)Microfacet models suffer from a significant limitation: they only simulate a single interaction between light and surface, ignoring the subsequent scattering across the microfacets. As a consequence, the BSDF is not energy ... -
Enforcing Scene Constraints in Single View Reconstruction
(The Eurographics Association, 2007)Three-dimensional reconstruction from a single view is an under-constrained process that relies critically upon the availability of prior knowledge about the imaged scene. This knowledge is assumed to be supplied by a user ... -
Engaging and Shared Gesture-based Interaction for Museums - The Case Study of K2R International Expo in Rome
(IEEE, 2015)This paper presents a full life-cycle production and standardized workflow to deploy a shared and engaging gesturebased experience within a museum, connecting two different natural interaction applications. The research ... -
Engaging audiences with Cultural Heritage through Augmented Reality (AR) Enhanced Pop-Up Books
(The Eurographics Association, 2020)One of the core activities of memory institutions is to provide access to heritage material from their collections so that it can be used in formal and informal educational activities. Although this type of access is ... -
Engaging Community Members with Digitally Curated Social Media Content at an Arts Festival
(IEEE, 2015)Capturing, uploading, and presenting social media content online have become the standard way for people to share their experiences with friends, family members, and others. In this paper, we describe our effort to extract, ... -
Engaging Virtual Agents
(The Eurographics Association, 2021)Embodied virtual assistants normally don't engage the user emotionally. They fulfil their functions, e.g. as shopping assistants or virtual teachers, factually and emotionless. This way, they do not explore the full potential ... -
