S-buffer: Sparsity-aware Multi-fragment Rendering
(The Eurographics Association, 2012)This work introduces S-buffer, an efficient and memory-friendly gpu-accelerated A-buffer architecture for multifragment rendering. Memory is organized into variable contiguous regions for each pixel, thus avoiding limitations ... -
S3Dc: A 3Dc-based Volume Compression Algorithm
(The Eurographics Association, 2008)Volumes acquired for medical purposes are continuously increasing in size, faster than graphic cards memory capacity. Large volumetric datasets do not fit into GPU memory and therefore direct rendering is not possible. ... -
SA3D, um Sistema de Animação para Ambiente de Microcomputador
(The Eurographics Association, 2023)Descreve-se a arquitectura do Sistema de Animação 3D (SA3D), um Sistema de Animação Modelada por Computador desenvolvido no projecto CAD/CAM no INESC, sob o ponto de vista da funcionalidade dos diferentes módulos constituintes ... -
SaarCOR - A Hardware Architecture for Ray Tracing
(The Eurographics Association, 2002)The ray tracing algorithm is well-known for its ability to generate high-quality images and its flexibility to support advanced rendering and lighting effects. Interactive ray tracing has been shown to work well on clusters ... -
SADIST: an Interactive Editor for Structured Analysis
(Blackwell Publishing Ltd and the Eurographics Association, 1983)An interactive editor for a computer-aided documentation system based on Structured Analysis (SA) is described. The paper investigates the potential offered by computer graphics in the implementation of the editor and ... -
Safe Walking Zones: Visual Guidance for Redirected Walking in Confined Real-World Spaces
(The Eurographics Association, 2018)Walking is usually considered the most natural form of self-motion in a virtual environment (VE). However, the confined physical workspace of typical virtual reality (VR) labs often prevents natural exploration of larger ... -
SAFE: Structure-aware Facade Editing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Many man-made objects, in particular building facades, exhibit dominant structural relations such as symmetry and regularity. When editing these shapes, a common objective is to preserve these relations. However, often ... -
SafeGI: Type Checking to Improve Correctness in Rendering System Implementation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Historically, rendering system development has been mainly focused on improving the numerical accuracy of the rendering algorithms and their runtime efficiency. In this paper, we propose a method to improve the correctness ... -
Safeguarding our Dance Cultural Heritage
(The Eurographics Association, 2022)Folk dancing is a key aspect of intangible cultural heritage that often reflects the socio-cultural and political influences prevailing in different periods and nations; each dance produces a meaning, a story with the help ... -
SAGISc: Sistema Colaborativo para Recolha de Dados Geológicos
(The Eurographics Association, 2021)A produção de cartografia geológica por processos convencionais é um trabalho complexo de recolha e integração de dados, assim como de consulta a especialistas e colegas de equipa. Esta complexidade implica uma elevada ... -
SAH Guided Spatial Split Partitioning for Fast BVH Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a new SAH guided approach to subdividing triangles as the scene is coarsely partitioned into smaller sets of spatially coherent triangles. Our triangle split approach is integrated into the partitioning stage ... -
SAH KD-Tree Construction on GPU
(ACM, 2011)KD-tree is one of the most efficient acceleration data structures for ray tracing. In this paper, we present a kd-tree construction algorithm that is precisely SAH-optimized and runs entirely on GPU. We construct the tree ... -
SailVis: Reconstruction and Multifaceted Visualization of Sail Shape
(The Eurographics Association, 2021)While sailing, sailors rely on their eyes to inspect the sail shape and adjust the configurations to achieve an appropriate shape for a certain the weather condition. Mastering this so-called trimming process requires years ... -
Sala de Espectáculos Virtual: Articulação em Tempo Real dos Ambientes Visual e Acústico
(The Eurographics Association, 2021)Utilizando as ferramentas e técnicas de visualização e computação gráfica proporcionadas pelo Visualization Toolkit (VTK), foi desenvolvida uma aplicação para visualizar, manipular e editar modelos tridimensionais (3D) de ... -
A Salience-based Quality Metric for Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Salience detection is a principle mechanism to facilitate visual attention. A good visualization guides the observer s attention to the relevant aspects of the representation. Hence, the distribution of salience over a ... -
Saliency Clouds: Visual Analysis of Point Cloud-oriented Deep Neural Networks in DeepRL for Particle Physics
(The Eurographics Association, 2022)We develop and describe saliency clouds, that is, visualization methods employing explainable AI methods to analyze and interpret deep reinforcement learning (DeepRL) agents working on point cloud-based data. The agent in ... -
Saliency-aware Real-time Volumetric Fusion for Object Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a real-time approach for acquiring 3D objects with high fidelity using hand-held consumer-level RGB-D scanning devices. Existing real-time reconstruction methods typically do not take the point of interest into ... -
Saliency-driven Depth Compression for 3D Image Warping
(The Eurographics Association, 2014)Current compression methods compress depth images by incorporating 2D features, which leads to a loss of the detail of the original 3D object in the recovered depth image. The main idea of this paper is to augment 2D ... -
