Impostors of a 3D AMAP plant
(Pinus halepensis): the same 3D plant is
visualized here from 16 different directions
using a flat object (Fig. 6.

). Finally, the user can activate options of rendering
to add realism and immersion to the landscape such as: sky, clouds, sun, haze,
shadows, lake and stereo-vision.
Example of Application
In this chapter, we present an example of SLE visualisation for a landscape in the
South of France, resulting from different scenarios (Nespoulous
2004)
.
The Situation
For centuries, the North of the Mediterranean basin has been characterized by
complex and quick changes. These changes mark a break with the progressive
variations which took place since the Neolithic and contributed to manufacture
the landscape in mosaic which is considered as typical for the North of the
Mediterranean basin. The nature of these changes affecting biodiversity of the
Mediterranean basin raises the question of the impact of human activities on
biodiversity, which is a central stake in the development of territories (Cheylan
and Gumuchian
2002)
. The studied zone is the Pic Saint Loup region, located in
the department of Hérault at about 20 km to the Northwest of Montpellier (Fig. 6.

).
This territory is characterized by the mountain of the Pic Saint Loup reaching the
altitude of 658 m.
