4. CONCLUSION
Natural phenomenon simulation is considered a challenging field of computer graphics. Based on analyzing wave scales and wave spectrums, the authors discretizes adaptively wave spectrums to different single frequency, the data are applied in simulation model for simulating irregular long crest wave. Unique mesh model and texture mapping technology are also adopted to simulate wave in real-time.
