Fast Lines: a Span by Span Method
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
Straight line's scan conversion and drawing is a major field in computer graphics. Algorithm's time computation is very important. Nowadays, most of research papers suggest improvements of the DDA method that was first ...
Efficient and Handy Texture Mapping on 3D Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
There has been a rapid technical progress in three-dimensional (3D) computer graphics. But gathering surface and texture data is yet a laborious task. This paper addresses the problem of mapping photographic images on the ...
Data Intermixing and Multi-volume Rendering
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
The main difference between multi-volume rendering and mono-volume rendering is data intermixing. In this paper, we present three levels of data intermixing and their rendering pipelines in direct multi-volume rendering, ...
Creating Architectural Models from Images
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
We present methods for creating 3D graphical models of scenes from a limited numbers of images, i.e. one or two, in situations where no scene co-ordinate measurements are available. The methods employ constraints available ...
Interactive Cuts through 3-Dimensional Soft Tissue
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
We describe a physically based framework for interactive modeling and cutting of 3-dimensional soft tissue that can be used for surgery simulation. Unlike existing approaches which are mostly designed for tensorproduct ...
Occluder Shadows for Fast Walkthroughs of Urban Environments
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
This paper describes a new algorithm that employs image-based rendering for fast occlusion culling in complex urban environments. It exploits graphics hardware to render and automatically combine a relatively large set of ...
Comprehensive Halftoning of 3D Scenes
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
The display of images on binary output hardware requires a halftoning step. Conventional halftoning algorithms approximate image values independently from the image content and often introduce artificial texture that ...
A Shrink Wrapping Approach to Remeshing Polygonal Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
Due to their simplicity and flexibility, polygonal meshes are about to become the standard representation for surface geometry in computer graphics applications. Some algorithms in the context of multiresolution representation ...
