Adaptive trimming of cubic triangular Bézier patches
(The Eurographics Association, 2006)
We present a method to handle cubic trimmed triangular Bézier patches. This scheme makes use of levels of detail and surface subdivision to achieve a fast and flexible hierarchical data structure that is specially useful ...
Automatic architectural 3D model generation with sunlight simulation
(The Eurographics Association, 2006)
Nowadays, 2D architectural design is provided with many good tools. But it lacks efficient tools that could help designers in early stages of a project for tasks such as virtual prototyping or 3D model simulation. The 3D ...
Coherent Hierarchical Level-of-Detail (HLOD) Refinement Through Hardware Occlusion Queries
(The Eurographics Association, 2006)
We present a coherent hierarchical level of detail (HLOD) culling algorithm that employs a novel metric to perform the refinement of a HLOD-based system that takes into account visibility information. The information is ...
Perceived Quality of Simplified Polygonal Meshes: Evaluation using Observer Studies
(The Eurographics Association, 2006)
The complexity of a polygonal mesh model is usually reduced by applying a simplification method, resulting in a similar mesh having less vertices and faces. Although several such methods have been developed, it is not yet ...
Kit Assembly Helper in Augmented Reality
(The Eurographics Association, 2006)
This paper describes an augmented reality application that aids users in assembling an object originally in a kit format, i.e. the object is received unassembled, with ordered instructions steps on how to connect each ...
Skin Detection for Hand Gesture Interfaces using Assimilative Background
(The Eurographics Association, 2006)
This paper describes the study realized about hand movement capture systems oriented to gesture interfaces. Thanks to this study we have developed a skin colour based hand detection application. The state of the art already ...
Perception-based painterly rendering: functionality and interface design
(The Eurographics Association, 2006)
Painterly rendering (non-photorealistic rendering or NPR) aims at translating photographs into paintings with discrete brush strokes, simulating certain techniques (im- or expressionism) and media (oil or watercolour). ...
Grid Architecture for Distributed Rendering
(The Eurographics Association, 2006)
Rendering is the process by means of which a raster 2D image can be obtained from the definition of a 3D scene. This process is computationally intensive and requires a lot of time to be done when the source scene has ...
Transferring Facial Expressions to Different Face Models
(The Eurographics Association, 2006)
We introduce a facial deformation system that helps the character setup process and gives artists the possibility to manipulate models as if they were using a puppet. The method uses a set of labels that define specific ...
Individualizing the New Interfaces: Extraction of User's Emotions from Facial Data
(The Eurographics Association, 2006)
When developing new multimodal user interfaces emotional user information may be of great interest. In this paper we present a simple and computationally feasible method to perform automatic emotional classification of ...
