SECTION #U6R3DX Abstract

EXCERPT #BU5SKV p. 0
  In this paper, we present a framework for representing complex terrains with such features as overhangs, arches and caves and including different materials such as sand and rocks. Our hybrid model combines a volumetric discrete data structure that stores the different materials and an implicit representation for sculpting and reconstructing the surface of the terrain. Complex scenes can be edited and sculpted interactively with high level tools. We also propose an original rock generation technique that enables us to automatically generate complex rocky sceneries with piles of rocks without any computationally demanding physically-based simulation.

SECTION #5JW9F9 8. Conclusion

EXCERPT #BELMDM p. 9
  We have presented an original approach for representing complex terrains. Our framework can model overhangs, arches, or caves with granular materials such as sand and rocks. Our hybrid model combines a compact material layer data structure and an implicit representation for sculpting and reconstructing the surface of the terrain. We have proposed several high level tools for authoring complex scenes.

EXCERPT #L338ZA p. 9
  In particular, we presented a very efficient erosion tool as a modeling operator for automatically generating rock and sand piles. Our approach allows the designer to sculpt large complex rocky scenes without computationally demanding physically-based simulation. Our system has been used to successfully construct a vast variety of scenes with original and unique geological features.

EXCERPT #NR4XNK p. 9
  In the future, we plan to develop new modeling and simulation tools. We are currently working on combining erosion and ecosystem simulation with a view to creating a unified framework for generating highly detailed and convincing grounds covered with vegetation but also with lichens, mosses, broken branches or fallen leaves. We also plan to investigate the generation of aperiodic rock tiles to improve the overall aspect of rocky sceneries.
