Morphing Rational B-spline Curves and Surfaces Using Mass Distributions
(Eurographics Association, 2003)
A rational B-spline curve or surface is a collection of points associated with a mass (weight) distribution. These mass distributions can be used to exert local control over the morph between two rational B-spline curves ...
Improved Indirect Photon Mapping withWeighted Importance Sampling
(Eurographics Association, 2003)
This paper offers a novel approach to the indirect photon mapping method. The placement of photons acting as virtual light sources is regarded as a cheap sampling scheme, allowing for the reuse of a complete shooting path ...
The Virtual Painting Paintbox
(Eurographics Association, 2003)
We present VPUP8 a new kind of paint boxes. It includes a model for the simulation of physic dynamics involved in the painting process and a human-machine interface to manage the position and the moves of the user. Usually ...
Parallel Visibility Test and Occlusion Culling in Avango Virtual Environment Framework
(Eurographics Association, 2003)
Real-time visibility test is an attractive feature for Virtual Environment (VE) applications where large datasets should be interactively explored. In such scenes most of the objects are usually occluded by other ones, and ...
Trans-Polygon Stroke Method for Frame Coherent Pastel Images
(Eurographics Association, 2003)
We propose Trans-Polygon Stroke Method (TPSM) for creating pastel-like animation that keeps frame-to-frame coherence. There are several variable factors in hand-drawn pastel such as paper roughness and pigments. When these ...
A Framework for Video-based and Hardware-Accelerated Remote 3D-Visualization
(Eurographics Association, 2003)
This paper presents a framework for video-based and hardware-accelerated remote 3d-visualization that produces and delivers high quality video streams at an accurate frame rate. The framework is based on the portable ...
Particle-based Collision Detection
(Eurographics Association, 2003)
In the paper we present a novel algorithm for collision detection between complex geometric objects represented by polygonal models and undergoing rigid motions and deformations. Most algorithms described in the literature ...
Continuous Local Parameterization of Polygons
(Eurographics Association, 2003)
Texture mapping has now become a standard technique for adding visual details to 3d models. Nevertheless, intuitive mapping tools have made little progress in the past decade, compared to other computer graphics areas: ...
ActiveInk
(Eurographics Association, 2003)
The ActiveInk system integrates the advantages of real world painting techniques with computer graphics (CG) effects such as natural phenomenon animations (e.g., water, fire, snow, and clouds), attributes (e.g., rubber, ...
Occlusion Culling for Image-Based Rendering withWarping
(Eurographics Association, 2003)
The basic idea of the proposed algorithm is to reduce the number of depth pixels in Layer Depth Images (LDI) by culling the occluded ones before warping. The method combines the octree spatial subdivision concept with LDI ...
