Therefore, we improved the shape of the clusters as shown in Fig. 7 to generate
various deformations within the original rectangular cluster.
5 Experiments
The proposed method was implemented on a system with intel Core i7-3960X
CPU system running on Windows 7 64bit OS with 32GB RAM and three NVidia
Geforce GTX 580 graphics hardwares.
Fig. 8 shows the wave reflection at the surface boundary. The waves are plau-
sible reflected without any additional consideration or computation. Fig. 9 also
shows the wave reflection. The black-colored external object is located on the
surface, and the wave is reflected at the boundary when it hits the object.
Fig. 10 shows the interference effect of different waves. The proposed method
plausibly and eciently expresses the wave interference. The figures to the left
show the rendering results of interfering waves, and the figure to the right shows
the amplitudes of wave surface in order to highlight the interfering effect. Fig.
11 shows the water animation and rendering result with our method.
