Abstract : The goal of this thesis is the search for new techniques for generating digital content for video game applications. The lack of variety of objects and details strongly affects the realism of synthetic landscapes. In this context, a major bottleneck is the creation of graphical assets to create the scenes. To simplify and accelerate this task, we present methods to automatically generate graphical content with a view to creating large, convincing and realistic landscapes.We present a first category of method to create and edit quickly a vast variety of objects from an initial model provided by a graphic designer, under the constraint of low polygonal modeling. We also present a procedural method for generating of varieties of objects. Together, these methods can create many varieties of natural forms as well as roads, bridges and tunnels that can automatically adapt to the landform features of an input terrain.We propose another method, based on a physical simulation and heat transfer simulation to create winter landscapes that evolve over time depending on the weather conditions. This approach allows us to follow the evolution of the snowpack and the thickness of the ice that forms on the surface of a lake.
