Abstract

In recent years, virtual reality (VR) and augmented reality (AR) have been developed and applied to various simulations for business and commercial use. In these simulations, computer graphics (CG) becomes very important to express virtual objects, and there are many studies on the expression of cloth. Some optical properties of an object are necessary to represent cloth with CG. These optical properties depend on the material of the thread, the number of threads, and the thickness. Therefore it is difficult to represent clothes corresponding to these changes. This study proposes a method to formulate the reflection and transmittance that depend on the component of the cloths. To formulate the reflection, we use the Kubelka-Munk theory and the component of the cloth that can be easily obtained using a smartphone, etc.
