Abstract�� A real-time linear accumulation ocean wave spectrum algorithm was adjusted by disturbing weighted phasic and amplitude factors which meliorated the defective smooth figure of billows and stormy waves. Base on the synthetic natural environment (SNE) information such as stormy level, wind level, equalized wave amplitude, and average cycle, advanced real-time combining environmental influence algorithm was presented. Based on the psychoacoustics and musical acoustics, advanced storm wave parameter adjusting method was proposed, and then real-time sound implementation node was realized using audio equalizer. Runtime shading method for flowing texture was proposed, background texture was appended to original one after mirror-image generation and Gauss blur distortion. Texture graphical quality was modified and image noise was also reduced after this underline processing. A harmonic visual and audio virtual system combing SNE information was realized which testified the feasibility of the advanced storm wave spectrum.
Keywords�� virtual ocean   synthetic natural environment   spectrum parameter   acoustical adjusting   flowing texture   procedural shading
