GENERATING REALISTIC IMAGES ON THE COMPUTER THROUGH REAL LUMINOUS INTENSITY DATA AND RADIOSITY METHOD
Abstract
Simulation of luminous distribution and modeling techniques are widely used in generating realistic images. It is performed by modeling the interaction of light with an individual surface and combining emission, transmission and reflection effects among all the surfaces in the environment. In this study, a realistic image was generated in the simulation area created in computer environment by using real luminous intensity data. It was aimed to generate a realistic image of a table and chair in the simulation environment. A goniophotometer was used to obtain the real luminous intensity curves of the luminaire to be used in the simulation environment. Realistic images were generated by using the real luminous intensity data obtained by the goiophotometer through the radiosity method. Radiosity method was used to transfer the luminous intensity data to the computer. The level for stopping the radiosity method was decided through histogram analyses that were performed by using image processing techniques. When the change in the mean brightness value in the histogram value was 1% and below, iteration was stopped by the software. According to the results of the tests performed on the given example, it was observed that the real image could be generated after approximately 3000 iterations and that the change decreased below 1% after this value.
