For the purpose of developing the feature of ternary quantum-dot cellular automata (QCA), the simulation algorithm which is directed to its semiclassical model was compiled, then the simulations about three simple ternary QCA devices have been achieved by virtue of Matlab, the results confirm that these structure's behavior and physical truth accord perfectly. The simulations show that the behavior...
This paper proposes a simple real-time method for modeling and rendering clouds. The density of cloud is formed by simulating projected motion of cloud particles into 2D plane. And then we render it by using an algorithm that approximates single forward scattering in real-time. This method does not require any preprocess to shade the cloud. By using this method one can create a cloud very quickly...
Clouds play an important role for creating realistic images of outdoor scenes. Many methods have been proposed for modeling and rendering clouds. Among these methods, Dobashi et al. proposed a simple but efficient cloud rendering algorithm based on splatting algorithm and take into account single scattering in couds. This algorithm has been used in many papers to generate realistic clouds images....
