“…Thus, the application of recursive subdivision is very natural in working with synthetic or digital images. Apart from Wamock's algorithm for removal of hidden surfaces, similar or more elaborate approaches can be used in calculating and/or displaying spline curves or surfaces [33], perform calculations on CSG7 objects using quadtrees [32], digital filtering of images, global histogramming of digital imagesC371, parallelizing such time-consuming rendering procedures as ray uacing [35], especially on CSG objects, performing the calculations necessary to visualize volumes[381, etc.…”

Management of the communications among a set of concurrent processes arises in many applications and is a central concern in parallel computing. In this paper we introduce MANIFOLD: a co-ordination language whose sole purpose is to describe and manage complex interconnections among independent, concurrent processes. In the underlying paradigm of this language the primary concern is not with what functionality the Individual processes in a parallel system provide. Instead, the emphasis is on how these processes are interconnected and how their Interaction patterns change during the execution life d the system. This paper also includes an overview of our implementation of MANIFOLD.As an example of the application of MANIFOLD, we present a series of small manifold programs which describe the skeletons of some adaptive recursive algorithms that are of particular interest in computer graphics Our concern in this paper is to show the expressiveness of MANIFOLD, the feasibility of its Implementation and its usefulness in practke.Issues regarding performance and optimization am beyond the scope of thk paper.

Scientific visualization is one of the emerging techniques used to represent large multi-parameter data sets in a comprehensible way. Finite element method, as one of the largely used techniques to simulate the behavior of complex systems, typically produces large amounts of multidimensional data. This paper describes a visualization environment for the analysis of finite element data resulting from the integration of several techniques specifically optimized for the domain problem. In the first part of the paper introductory remarks are given on visualization and simulation. The finite element method is presented in more detail in order to keep the description of the system consistent with the paper. Subsequently, an overview of the logical functionality made available by the system is presented. In the second part of the paper, implemented algorithms dealing with the representation and the visualization of finite element data are detailed. Two different methodologies, together with their underlying algorithms, are considered which serve different purposes in the analysis task and in the dissemination of results.
