Abstract:		Physically based rendering often requires simulation the effects of wave optics such as dispersion, interference, diffraction. However, even if a model of the wave phenomenon is known we have a problem getting the input data for rendering because the majority of the available methods allows to get the color and intensity of the radiation, but not its spectrum. And devices for spectrum measuring are complex, expensive and difficult to access. This article describes a simple and flexible iterative method for the spectrum construction from RGB color, which allows to build the result taking into account the specified limitations relevant to rendering task requirements.
