"A Simple, Efficient Method
for Realistic Animation of Clouds
Yoshinori Dobashi * Kazufumi Kaneda ** Hideo Yamashita ** Tsuyoshi Okita *
Tomoyuki Nishita ***

abstract:
This paper proposes a simple and computationally inexpensive
method for animation of clouds. The cloud evolution is simulated
using cellular automaton that simplifies the dynamics of cloud
formation. The dynamics are expressed by several simple
transition rules and their complex motion can be simulated with a
small amount of computation. Realistic images are then created
using one of the standard graphics APIs, OpenGL. This makes it
possible to utilize graphics hardware, resulting in fast image
generation. The proposed method can realize the realistic motion
of clouds, shadows cast on the ground, and shafts of light through
clouds.


si vous le trouvez pas, je le mettrais online.
