Evolving Body Kinematics for Virtual Characters
(The Eurographics Association, 2006)Physically-based character animation systems often require complex knowledge of the underlying equations of motion. Hence, producing physically-realistic animations can be time consuming with these systems. In this paper, ... -
Expeditious Modelling of Virtual Urban Environments with Geospatial L-systems
(The Eurographics Association, 2006)This paper presents Geospatial L-systems, a new extension of L-systems that incorporates geospatial awareness, and shows an application of this new tool in the expeditious modelling of urban environments, integrated with ... -
Experiences From the Development of a Prototype of an Spatial Augmented Reality System
(The Eurographics Association, 2018)This paper describes the hardware and software of a prototype of a portable Spatial Augmented Reality system. This prototype is completely autonomous and projects the information on the real world, so that it is visible ... -
Experiência de Realidade Virtual Imersiva no Ambiente CaveHollowspace do Lousal
(The Eurographics Association, 2021)Este artigo descreve o ambiente de realidade virtual imersiva CaveH, instalado no Centro de Ciência Viva do Lousal, focando-se nas suas componentes e na sua concretização. Descreve também o processo de desenvolvimento ... -
Experiências com Ray Tracing. Necessidade de Arquitecturas Paralelas
(The Eurographics Association, 2023)O Ray Tracing e a Radiosity são as técnicas de síntese de imagens que, na actualidade, produzem imagens com maior grau de realismo. Um sistema CAD dotado com estas técnicas poderá ser de grande utilidade numa empresa, quer ... -
An Experimental Setup to Evaluate the Performance of Tone Mapping Algorithms
(The Eurographics Association, 2006)Many algorithms have been proposed in the literature to solve the problem of mapping tones from high dynamic range sources to low dynamics displays, while preserving the information conveyed by the original scene. Methods ... -
Explaining Neighborhood Preservation for Multidimensional Projections
(The Eurographics Association, 2015)Dimensionality reduction techniques are the tools of choice for exploring high-dimensional datasets by means of low-dimensional projections. However, even state-of-the-art projection methods fail, up to various degrees, ... -
Explicit Adaptive Tessellation based on re-parametrization on Graphics Hardware
(The Eurographics Association, 2007)We propose to use an explicit function for adaptive tessellation of parametric curves and surfaces. This function behaves as a new parametrization from the surface domain (or curve domain) to the domain itself; it is build ... -
Exploiting Silhouette Descriptors and Synthetic Data for Hand Gesture Recognition
(The Eurographics Association, 2015)This paper proposes a novel real-time hand gesture recognition scheme explicitly targeted to depth data. The hand silhouette is firstly extracted from the acquired data and then two ad-hoc feature sets are computed from ... -
Exploração da Remoção Hierárquica por Oclusão em Simulações em Tempo Real
(The Eurographics Association, 2021)As aplicacoes de simulacao grafica em tempo real podem apresentar um fraco desempenho devido a complexidade de ambientes virtuais de muito grandes dimensoes. Um exemplo ea simulacao de conducao em ambientes urbanos onde ... -
Exploração e Visualização de Informação Pessoal
(The Eurographics Association, 2021)Hoje em dia, a constante interacção com sistemas computacionais faz com que seja gerada uma elevada quantidade de informação pessoal. Contudo, é difícil termos uma vis˜ao global dos nossos dados e encontrar padr˜oes na ... -
Exploração Interactiva de Colecções Musicais usando Treemaps Ordenados Semanticamente
(The Eurographics Association, 2021)Neste artigo apresentamos o MuVis, uma nova abordagem para visualização e exploração interactiva de colecções de música, com base no conteúdo musical e informação semˆantica. A solução desenvolvida é constituída por três ... -
Exploração Interactiva dos Hábitos de Audição de Música
(The Eurographics Association, 2021)Devido `a expansão da Internet é comum as pessoas utilizarem servic¸os online para registarem detalhes acerca das suas vidas, tais como os hábitos de audição de músicas. Embora estes serviços disponibilizem alguns dados ... -
Exploring Face Recognition under Complex Lighting Conditions with HDR Imaging
(The Eurographics Association, 2016)Applying image processing applications under complex or harsh lighting conditions can be a difficult challenge. In particular, face recognition can be prone to such limitations due to the uncontrolled nature of the ... -
Exploring Language Pedagogy with Virtual Reality and Artificial Intelligence
(The Eurographics Association, 2023)Virtual Reality (VR) is a highly immersive and interactive experience that renders users to be engrossed in a 3D virtual environment. The recent technological advancements with high-resolution headset display, and accurate ... -
Exploring Upper Limb Segmentation with Deep Learning for Augmented Virtuality
(The Eurographics Association, 2021)Sense of presence, immersion, and body ownership are among the main challenges concerning Virtual Reality (VR) and freehand-based interaction methods. Through specific hand tracking devices, freehand-based methods can allow ... -
Expressive and Dynamic Deformation of Animated Computer-Generated Characters
(The Eurographics Association, 2006)3D computer animated characters often lack the communicative power and the expressiveness of traditional animation, especially when used in non-photorealistic graphical representations. Inspired by a talk by Pixar Animation ... -
