Discoloration Simulation in Digital Contents Creation using Experimental Data of Daylight

In this study, we will discuss how to make discoloration using an algorithm.Discoloration is a phenomenon that occurs naturally when a surface in contact with oxygen receives light for a certain period or longer.Several main factors cause discoloration, such as the period value and intensity of the wavelength of radiant energy.However, time is a very important factor in addition to these factors.No matter how short the wavelength or increasing the intensity, obtaining the desired discoloration value within a short period is difficult.Using PicMan, based on the color change data obtained by interpolating the difference between the image before an after discoloration, there is a method of calculating the additional color change value using the extraintestinal method and outputting the additional color change scene.Still, it is difficult to output the color change value at the desired time because it was calculated only by the difference value between the data obtained from the two images before and after the color change progressed.Therefore, in this study, we would like to introduce a texture image discoloration processing technique through the color movement of discoloration obtained by adding a time value and sunlight to the data extraction of discoloration by adding several types of confetti samples to sunlight.
