Method and Model for a Highly Realistic Rendering of a Three-Dimensional Image

Abstract

The formation of color components of face images is a complex computational task, since for each pixel of a surface it is necessary to calculate the color intensity, for which it is necessary to determine the unit vectors to the light source and normal to the surface. Therefore, the urgent task is to simplify the coloring procedure without losing the realism of the final image. It is suggested to use second-degree and third-degree polynomials to adapt to painting, depending on the surface curvature. For the third degree polynomial, an approximation formula is obtained to determine the diffuse and specular color components. The hardware for determining the coefficients and the approximation polynomial is proposed
