Formation of color components of image areas of a face is a complex computational problem, since for each pixel of a surface it is necessary to calculate the intensity of color, for which it is necessary to define single vectors to the source of light and normal to the surface. Therefore, the actual task is simplification of the procedure of painting the significant loss of the realism of the final image.
It is proposed to use adaptive polynomials of second and third degrees depending on the curvature of the surface to painting. For a polynomial of the third degree, an approximation formula is obtained for determining the diffuse and specular components of color. The hardware for the determination of coefficients and the approximation polynomial is proposed
