Divide and Conquer Spot Noise
نویسنده
چکیده
The design and implementation of an interactive spot noise algorithm is presented. Spot noise is a technique which utilizes texture for the visualization of flow fields. Various design tradeoffs are discussed that allow an optimal implementation on a range of high end graphical workstations. Two applications are given: the steering of a smog prediction simulation and browsing a very large data set resulting from a direct numerical simulation of turbulence. These applications provide the motivation for the need of interactive visualization techniques.

This paper presents the structural design for huge systems using Divide & Conquer (D&C) method as a scientific method for optimum designing of complex systems. This method divides the main system into several simple subsystems. Submitted equations in three different cases prove that the optimum response (number of subsystems for minimum system complexity) is independent of main system complexit...
متن کاملPreliminary Result of Parallel Double Divide and Conquer
This paper shows a concept for parallelization of double Divide and Conquer and its preliminary result. For singular value decomposition, double Divide and Conquer was recently proposed. It first computes singular values by a compact version of Divide and Conquer. The corresponding singular vectors are then computed by twisted factorization. The speed and accuracy of double Divide and Conquer a...
متن کاملA Divide-and-Conquer Approach to Contour Analysis and Extraction of Invariant Arc Features
This paper presents a newl divide-and-conquer method to analyze geometric shapes, contours and trajectories extracted as a discrete sequence of points (or pixels) from images or spatial sensors such as GPS or transponders. The method converts contour point sequences into Circular Augmented Rotational Trajectories (CART) and uses a scale invariant analysis to extract invariant arc features. The ...
متن کاملDivide and Conquer
An instance of the given problem is divided into easier instances of the same problem, which are solved recursively and then combined to create a solution to the original instance. Of course, divide and conquer is not suitable for every problem. A divide and conquer approach will only work if the problem is easily divided into a small number of easier sub-problems, and the solution to the entir...
