![]() This is often referred to as task parallelism.ĭata-intensive is used to describe applications that are I/O bound or with a need to process large volumes of data. In compute-intensive applications, multiple operations are performed simultaneously, with each operation addressing a particular part of the problem. Parallel processing of compute-intensive applications typically involves parallelizing individual algorithms within an application process, and decomposing the overall application process into separate tasks, which can then be executed in parallel on an appropriate computing platform to achieve overall higher performance than serial processing. Such applications devote most of their execution time to computational requirements as opposed to I/O, and typically require small volumes of data. Compute-intensive is used to describe application programs that are compute bound. Parallel processing approaches can be generally classified as either compute-intensive, or data-intensive. Data-intensive computing is intended to address this need. The storing, managing, accessing, and processing of this vast amount of data represents a fundamental need and an immense challenge in order to satisfy needs to search, analyze, mine, and visualize this data as information. In a 2003 study of the so-called information explosion it was estimated that 95% of all current information exists in unstructured form with increased data processing requirements compared to structured information. An IDC white paper sponsored by EMC Corporation estimated the amount of information currently stored in a digital form in 2007 at 281 exabytes and the overall compound growth rate at 57% with information in organizations growing at even a faster rate. Vinton Cerf described this as an “information avalanche” and stated “we must harness the Internet’s energy before the information it has unleashed buries us”. In addition, business and government organizations create large amounts of both structured and unstructured information which needs to be processed, analyzed, and linked. ![]() Constant shading can be useful for quickly displaying the general appearance of a curved surface.The rapid growth of the Internet and World Wide Web led to vast amounts of information available online.the vector position is sufficiently far from the surface so that the unit vector pointer to the viewer from the surface position, a unit vector in the diversion of ideal specular reflection is constant over a surface.Light sources illuminating the objects are sufficiently far from the surface so that the unit is normal to a surface unit direction vector to the point light source from a position on a surface and attenuation is constant over the surface.The object is a polyhedron and is not an approximation of an object with a curved surface.In general, flat shading of polygon facets provides an accurate rendering for an object if all the following are valid: In this method, the main idea is that we use only one surface normal per polygon. This technique thus displays all the points in a polygon with a single color. In this method, a single intensity is calculated for each polygon. Flat shading of a polygon assumes that each polygon is strictly planar and all the points on the polygon have exactly the same blind light treatment. This is the most simple and very fast method to specify a color of an object. Constant intensity is also known as flat shading. In computer graphics shading is referred to as the process of altering the color of an object in the 3D scene based on the surface angle to lights, its distance from the light, and the material properties.
