Shortest Circuits with Given Homotopy in a Constellation
(The Eurographics Association, 2004)
Abstract A polynomial method is described for computing the shortest circuit with a prescribed homotopy on a surface. The surface is not described by a mesh but by a constellation: a set of sampling points. Points close ...
Real-Time Capture, Reconstruction and Insertion into Virtual World of Human Actors
(The Eurographics Association, 2003)
In this paper, we show how to capture an actor with no intrusive trackers and without any special environment like blue set, how to estimate its 3D-geometry and how to insert this geometry into a virtual world in real-time. ...
Implicit Curve and Surface Design Using Smooth Unit Step Functions
(The Eurographics Association, 2004)
This paper presents an implicit curve and surface design technique that uses smooth unit step functions. With the proposed method, an implicit curve or surface can be generated by inputting a sequence of points together ...
Extending Natural Textures with Multi-Scale Synthesis
(The Eurographics Association, 2003)
This paper presents a texture synthesis algorithm that was designed for the tile-less generation of large images of arbitrary size from small sample images. The synthesised texture shows features that are visually similar ...
Quasi-3D cell-based Animation
(The Eurographics Association, 2003)
We present a method for image compositing and rendering using 2D geometric shapes or raster images as input primitives, disposed in a 3D environment around which the camera can move. An animation system has been implemented ...
Regularised Anisotropic Nonlinear Diffusion for Rendering Refraction in Volume Graphics
(The Eurographics Association, 2005)
Rendering refraction in volume graphics requires smoothly distributed normals to synthesise good quality visual representations. Such refractive visualisation is more susceptible to noise in the data than visualisations ...
Towards a new Camera Model for X3D
(The Eurographics Association, 2009)
Creating and setting the right parameters for the virtual camera is crucial for any content creation process. However, this is not easy since most current camera models, including the X3D Viewpoint, use a 3D position and ...
Investigating Occlusion and Discretization Problems in Image-Based Blurring Techniques
(The Eurographics Association, 2003)
Traditional computer graphics methods render images that appear sharp at all depths. Adding blur can add realism to a scene, provide a sense of scale, and draw a viewer's attention to a particular region of a scene. Our ...
