Adaptive mesh generation for progressive radiosity: A ray-tracing based algorithm.
(Blackwell Science Ltd and the Eurographics Association, 1994)
The radiosity method is one of the most popular rendering algorithms. It allows to simulate interreflections of light accurately between surfaces as energy transfers are well designed. However, this algorithm and its ...
Chebyshev Polynomials for Boxing and Intersections of Parametric Curves and Surfaces
(Blackwell Science Ltd and the Eurographics Association, 1994)
Parametric curves and surfaces are powerful and popular modelling tools in Computer Graphics and Computer Aided Design. Ray-tracing is a versatile and popular rendering technique. There is therefore a strong incentive in ...
Triangulating multiply-connected polygons: A simple, yet efficient algorithm.
(Blackwell Science Ltd and the Eurographics Association, 1994)
We present a new, simple, yet efficient algorithm for triangulating multiply-connected polygons. The algorithm requires sorting only local concave minima (sags). The order in which triangles are created mimics a flooding ...
Parallel ray tracing based upon a multilevel topological knowledge acquisition of the scene
(Blackwell Science Ltd and the Eurographics Association, 1994)
Including the standard parallelization by grouping primary rays, this paper presents a new parallel ray-timing method based upon a topological knowledge acquisition of the scene. This topological knowledge focuses on ...
Designing and Implementing a Grid-Distortion Mapping Based on Variational Principles
(Blackwell Science Ltd and the Eurographics Association, 1994)
A grid-distortion mapping based on variational principles is described. The mapping is first defined between any two equivalent regular grids with minor geometric restrictions, and is then optimally extended to the interior ...
Selective Visualization of Vector Fields
(Blackwell Science Ltd and the Eurographics Association, 1994)
In this paper, we present an approach to selective vector field visualization. This selective visualization approach consists of three stages: selectdon creation, selection processing and selective visualization mapping. ...
A Formal Approach to the Specification of Graphic Object Functions
(Blackwell Science Ltd and the Eurographics Association, 1994)
Graphic objects are an abstract mathematical model for graphic systems. The model is an algebraic approach to represent graphic information, which include modelling operations. This formalism require some method to describe ...
A Median Cut Algorithm for Efficient Sampling of Radiosity Functions
(Blackwell Science Ltd and the Eurographics Association, 1994)
This paper presents an efficient method for sampling the illumination functions in higher order radiosity algorithms. In such algorithms, the illumination function is not assumed to be constant across each patch, but it ...
Reducing The Latency In Head-Mounted Displays By A Novel Prediction Method Using Grey System Theory
(Blackwell Science Ltd and the Eurographics Association, 1994)
In this paper we propose a novel prediction method for the head motion using Grey System theory, where a 6D tracker is attached to an HMD on a user s head in virtual reality applications. Our prediction method using Grey ...
Fast Wavelet Radiosity Method
(Blackwell Science Ltd and the Eurographics Association, 1994)
Wavelet analysis has been found [1] to be very useful for functional representation and accurate global solution of radiosity. In radiosity we deal with functions in 2D and 4D spaces. Under such conditions, the biggest ...
