In this paper, we present a real-time method to display ocean surface gravity waves for various computer graphics applications. Starting from a precise surface gravity model in oceanography, we derive its implementation model and our prototype implementation shows more than 50 frames per second on Intel Core2 Duo 2.40GHz PC’s. Our major contributions will be the improvement on the expression power...
Real world winds can be classified into two categories: natural winds and artificial winds. While previous researchers have focused on natural winds, we also need to simulate artificial winds, which may be generated by electric fans, air conditioners, human mouths, etc. In this paper, we present a mathematical model for artificial winds, and also present an efficient method for calculating the forces...
We describe two simple optimal-work parallel algorithms for sorting a list L = (X 1 , X 2 , , X m ) of m strings over an arbitrary alphabet Σ, where Σ mi=1 X i = n and two elements of Σ can be compared in unit time using a single processor. The first algorithm is a deterministic algorithm that runs in O(log 2 m/log log m) time and the...
