Combining Segmentations for Understanding and Annotating 3D Objects
(The Eurographics Association, 2008)In the last years, 3D objects have become widely available and are used in many application domains. Thus it is becoming fundamental to develop techniques for extracting and maintaining the knowledge embedded into 3D models. ... -
A Compact Tucker-Based Factorization Model for Heterogeneous Subsurface Scattering
(The Eurographics Association, 2013)This paper presents a novel compact factored subsurface scattering representation for optically thick, heterogeneous translucent materials. Our subsurface scattering representation is a combination of Tucker-based factorization ... -
Comparação de Dispositivos de Interacção em Ambientes de Realidade Virtual: Desenvolvimento de um Setup Experimental e Estudos com Utilizadores
(The Eurographics Association, 2021)A Realidade Virtual (RV) tem despertado um interesse crescente nos ultimos anos. Contudo a sua evolup'io tem sido mais lenta que o esperado, provavelmente devido a.o custo dos equipamentos, mas tambem as capacidades dos ... -
Comparação entre os algoritmos de simplificação NSA e Qslim usando a ferramenta PolyMeCo
(The Eurographics Association, 2021)Apresentam-se os resultados da comparação de algumas características de malhas triangulares geradas por dois algoritmos de simplificação: NSA e QSlim. Foram usados sete modelos originais e, para cada um, criados três modelos ... -
Comparative Visualization and Analysis of Time-Dependent, 2D Foam Simulation Data
(The Eurographics Association, 2014)Liquid foams have important practical applications. To analyze the dependence of foam behavior on material properties, and to improve foam models, foam scientists work with dozens of related simulations obtained by varying ... -
Comparing Gestural Interfaces using Kinect and OpenPose
(The Eurographics Association, 2019)We describe the implementation of a gesture recognition facility for navigating through virtual reality applications in a shared VR facility. An implementation based around the Microsoft Kinect is described and the fruits ... -
Comparison and Integration of Erosion Evaluation Methods for Rheumatic Degenerative Diseases
(The Eurographics Association, 2020)Monitoring the development of degenerative rheumatic diseases is at the core of an efficient medical evaluation of the patient. Acquiring information on the pathology progression, indeed, helps to personalize the therapy ... -
Comparison of Different Types of Visemes using a Constraint-based Coarticulation Model
(The Eurographics Association, 2010)A common approach to producing visual speech is to interpolate the parameters describing a sequence of mouth shapes, known as visemes, where visemes are the visual counterpart of phonemes. A single viseme typically represents ... -
Comparison of GPU-based Methods for Handling Point Cloud Occlusion
(The Eurographics Association, 2021)Three-dimensional point clouds have conventionally been used along with several sources of information. This fusion can be performed by projecting the point cloud into the image plane and retrieving additional data for ... -
A Comparison of Orthographic and Perspective Projections in the Generation of Textures for Billboards
(The Eurographics Association, 2021)Image-based rendering techniques take the approach of rendering new images based on existing ones, effectively separating the rendering complexity from the geometric complexity of the scene they represent. With the advance ... -
Compositing Shaders in X3D
(The Eurographics Association, 2011)We present a new approach for implementing effects using the GPU shading languages. Our effects seamlessly cooperate with each other and with the shaders used internally by the 3D application. Thus the effects are reusable, ... -
Composition of Texture Atlases for 3D Mesh Multi-texturing
(The Eurographics Association, 2010)We introduce an automatic technique for mapping onto a 3D triangle mesh, approximating the shape of a real 3D object, a high resolution texture synthesized from several pictures taken simultaneously by real cameras surrounding ... -
Compressed SVG Representation of Raster Images Vectorized by DDT Triangulation
(The Eurographics Association, 2006)This paper presents a portable compression algorithm applied to raster data images properly triangulated by using DDT (Data Dependent Triangulation). In particular the input source data are encoded to be rendered by standard ... -
Compressive High Speed Video Acquisition
(The Eurographics Association, 2015)Traditional video capture is limited by the trade-off between spatial and temporal resolution. When capturing videos of high temporal resolution, the spatial resolutions decreases due to bandwidth limitations in the capture ... -
Computação Gráfica e Arqueologia Urbana: o caso de Bracara Augusta
(The Eurographics Association, 2021)A Computação Gráfica é, seguramente, uma ferramenta importante, e crescentemente utilizada, para representar e manipular grandes quantidades de informação de elevada complexidade. Por sua vez a arqueologia, de uma forma ... -
A Computação Gráfica e o Ensino Assistido por Computador
(The Eurographics Association, 2023)No presente trabalho, depois de passar em revista alguns aspectos pedagógicos e cognitivos relacionados com a actividade de ensino, prestar-se-á atenção ao papel da Computação Gráfica no ensino assistido por computador e ... -
