Scratches are placed onto the part using an image pattern, which can be created (painted) directly onto the part or obtained from the treatment of a real image, for example. The reflection properties of scratches are defined by measuring the real scratched surfaces or by hand, allowing the use of any model of reflection. (more...)

Next images show the results of simulating a part with a scratch, viewed from different points of view (up vs. down) and comparing the real photographs with the simulated images (left vs. right):
