Creación de un software con programación concurrente para la iluminación y sombreado de superficies vectoriales utilizando gradientes vectoriales.

Abstract

In the present work of qualification a software with Concurrent programming was created for the lighting and shading of vector surfaces using vector gradients. For development of application and of the prototype used tools: C++, OpenGL and Visual Studio as an integrated Development Environment (IDE). For the analysis of concurrent programming on the Graphics Processing Unit (GPU) and Central Programming Unit (CPU), used for the following tools: Debugger, Fraps and the Windows system monitor, with which was possible to perform the measurements of the prototype. The analytical method was used with which the data obtain after the measurements were analyzed. The result obtained were: at runtime; GPU executed the algorithm in 20 seconds versus the 45 seconds that took in CPU; Frames Per Second (FPS): 8 fps on CPU and 18 fps on GPU; Processor usage: 67 % on CPU versus 10% on GPU; Memory usage in megabytes: 48 MB in GPU; and 86 MB in CPU. The measurements of the parameters were made on a prototype built for the purpose, with which it was obtained that the GPU technology is most suitable to deploy the application Fractal Build, being superior in each one of the parameters analyzed, obtaining 75 points in the summation, over 14.5 points obtained by the CPU technology. For the analyzed it was concluded that the used use of the GPU technology is most suitable because of the advantages that is offers when executing a graphical application. It is recommended to continue with the study of the implementations on GPU as General-Purpose Processor due to its multiple benefits.
