The purpose of this study was to make the sea with rending of ocean by using the proper algorithm for anemotional online game. We used statistical model to make the sea in this study. In measuring the wave height,we used Fast Fourier Transformation (FFT) to calculate the sum of amplitude and phrase quickly with randomnumbers of the time. We eliminated the overlap functions of sine and cosines by using the repeatability of trigonometric function. We saved the values of trigonometric function in memory space. Therefore, we could deal with the repetitivecalculations by memory access because the same values are repeated in the standard based on within one cycleof 2 in sine and cosine functions. By changing the sampling size of Windows function, we calculated the mobility on each local area and weapplied this mobility to this study according to hierarchical structure. In addition, we used the reflectivitydifferently by putting the value of into the effect Fresnel reflection. The reason why we used this methodwas to make the sea look more realistic. In the aspect of the intensity of light of the sea, we did not calculate it and we applied KD- Tree data structureon the density of the values occurred at the time of the sea was created. The advantage of this method was toreduce search time effectively. In this Tree structure, index time log, search time and log time arespend, which is applied to the photon closed to. In the case of KD-Tree, this is a very effective way in savingand recovering. One weakness was that we had to limit the effect of indirect illumination to express a wide sea. However, by using photon mapping, we solved this problem
Abstract
The purpose of this study was to make the sea with rending of ocean by using the proper algorithm for anemotional online game. We used statistical model to make the sea in this study. In measuring the wave height,we used Fast Fourier Transformation (FFT) to calculate the sum of amplitude and phrase quickly with randomnumbers of the time. We eliminated the overlap functions of sine and cosines by using the repeatability of trigonometric function. We saved the values of trigonometric function in memory space. Therefore, we could deal with the repetitivecalculations by memory access because the same values are repeated in the standard based on within one cycleof 2 in sine and cosine functions. By changing the sampling size of Windows function, we calculated the mobility on each local area and weapplied this mobility to this study according to hierarchical structure. In addition, we used the reflectivitydifferently by putting the value of into the effect Fresnel reflection. The reason why we used this methodwas to make the sea look more realistic. In the aspect of the intensity of light of the sea, we did not calculate it and we applied KD- Tree data structureon the density of the values occurred at the time of the sea was created.
