ABSTRACT:
A method is provided for representing, on a display device screen and in perspective from a given point of observation, the image of a terrain known by the nodes of a given mesh network, in which for each image pixel, the point of intersection is determined of the line which starts from the point of observation and which passes through this image pixel with a surface passing through the nodes and taking on approximately the shape of the ground, and said image pixel is illuminated with the color of the pixel associated with a digitized planimetric map or photograph of the ground.
