Abstract

Ray tracing is a technique in computer graphics that produced image by traversing ray from eye to every pixels on screen, and then the intersection checks between ray and objects are done. Ray tracing can produce a photorealistic image, but needs a long time to do the computations. One of the ways to shorten the computation time is by reducing the number of intersection checks between ray and objects. One of the popular methods is Bounding Volume Hierarchy (BVH).In this application, Compute Unified Device Architecture (CUDA) is also used beside BVH. The CUDA’s usage purpose is to reduce computation time by doing parallel computing in the GPU. Computations done in GPU are computing ray directions from eye to every pixels and color of every pixels.The result of this application is more than 70% rendering time reduced when compared to ray tracing application with only BVH. The maximum reduction is 86%.

Abstract

The search process for domestic services have tended to be difficult because of the lack of centralized information media. The process of offering services performed by service providers is also difficult because of the absence of promotional media that can be accessed by service customers. Based on these requirements, crowdsource application was made for the services of domestic workers that can be a source of information as well as to help connecting service customers with service providers. Crowdsource application for the services of domestic workers is designed into a Service Provider Application, a Service Customer Application, and a Registration and Administrator Website. Registration Website is used to allow users to enroll as a provider. The website also serves for the administrator to accept or reject registration and to activate or deactivate an account. Service Provider Application and Service Customer Application function to communicate with each other in order to reach an agreement of supply and demand services. The results show that the Service Provider Application and Service Customer Application can provide the necessary information and help users communicate, negotiate, and reach an agreement. Review and report violations feature helps to evaluate every element in the application, both service providers, service customers, demand, and supply.
