Abstract
Visualizing objects that are illuminated by light and reflected from its surrounding objects can be performed using radiosity method. In the method, a multitude of rays from a light source must be traced until it can be determined that the ray does not collide with any objects in the environment, or the ray intensity is too weak to be engaged in the final intensity calculation. The process of tracing the rays must be repeated for each ray that collides to any object. Based on this concept, it is no wonder that radiosity will take a lot of time in its rendering process. Fortunately, rays that need to be traced in radiosity are independent one another. A server-client parallel processing is used in this research to parallel the process in radiosity. Server will assign some rays to be traced to clients. After clients finished their jobs in tracing rays, they can send the result back to server to be used to render the objects. From the experiment, it can be concluded that the performance in paralleling the process in radiosity can be considered good. Increasing the number of clients can significantly reduce the time required to finish the job. Therefore a certain company can use several idle computers as clients to decrease the time required to get the final result. It can also be concluded as well that the system has some limits in employing the number of clients. At a certain point, adding more clients will not anymore decrease significantly the time required to get the result. This problem occurs from the phenomenon of the efficiency decremental as the number of clients increases.
