Details in NAtural scenes


Project motivation

Modelling, simulating and rendering complex natural scenes form a perennial challenge that has many applications not only in the entertainment industry, but also in landscape design, risk prevention and National Monuments preservation. Several very specific techniques and systems have been proposed for modelling landscapes, simulating some ecosystems and representing some categories of plants. Unfortunately, the proposed models are so diverse that they cannot be unified in a common framework.

The challenge stems from the complexity and diversity of objects interacting together and with their environment. Beautiful images have been produced by computer graphics researchers and artists in the film industry. Unfortunately, the rendered models are often too perfect, which betrays the synthetic nature of the scene. Details such as fallen autumn leaves, lichens or mosses, cracks and fractures, shells in sand, rust and eroded stones on monuments, are conspicuous in nature. Therefore, there is a need for an integrated framework capable of handling and processing a massive amount of small details that play a very important part in the realism of a complex scene.

In this project, we intend to set up such an integrated and unified framework for modelling and simulating the evolution of details over complex objects in natural scenes. We will focus both on organic (trees, grass, mosses) and inorganic (stones, sand, metallic objects) objects interacting together in with their environment.
