Abstract: Image synthesis is highly dependent on rendering algorithm and optical properties of scenario objects. The goal of this work is to develop a methodology to obtain some illumination parameters of a real scenario represented by an acquired image, and use these parameters for a virtual scenario rendering with the same objects as the original. The proposed methodology consists, first, in acquiring an image of the working scenario, and by using a DE (Differential Evolution) algorithm to render images that gradually approximate to the real acquired image, by some virtual scenario parameter modification based on the DE optimization. We call it “ED Rendering in the loop”. Finally we use the obtained parameters to render an image to compare it with similar methods.
