The forest fire probably resulted in smoke, which may render the illumination more diffuse. Rather than a single concentrated light source, we end up with illumination from a relatively area of the sky. This could make the task much more difficult because we are less able to predict the brightness associated with a given surface orientation. You have reason to believe that the surface of the mountains is unusually rough in this area. You have been told the location in the photograph of two peaks.
Peaks are points at which the surface normal is approximately in the direction of the camera.
The known orientations of these points can be used to anchor the relaxation algorithm. The labels indicate how the vertices in the different views correspond to each other. The vertices that are visible in each view are not the same ones. First, list briefly the steps you will have to go through to solve the problem. Pick a candidate model from the database.
