Abstract: The general field of the invention is that of methods of three-dimensional synthetic representation of a terrain. These methods are implemented in a vehicle piloting and navigation aid system. The method according to the invention comprises the following steps: Step 1: Computation, for a determined position of the vehicle, of a first part or of the entirety of the terrain seen through the viewing system; Step 2: Computation, for the said terrain portion, of the curvature of the said terrain at each point; Step 3: Computation, as a function of the position and of the orientation of the carrier, of the position of the displayed points; Step 4: Computation of the luminance of each point of the said visible terrain portion according to a determined law, dependent on the said curvature; Step 5: Display by the viewing system of the luminance of each point.
