【摘要】：本文通過分析三角函數(shù)的泰勒展開式,提出了一種利用多項式函數(shù)優(yōu)化三角函數(shù)的計算方法,用于改善虛擬系統(tǒng)中水波模擬的實時性。本算法中,通過引入多種控制波形的參數(shù),實現(xiàn)了水波波形的多樣性。在此基礎(chǔ)上,還提出了一種計算表面法向量的方法,以便更好地與周圍環(huán)境及光線進行交互。選用自然水波圖像作為參考,并與當(dāng)前典型算法Gerstner和FFT算法進行性能對比。實驗結(jié)果表明,本文算法能生成豐富、自然的水波運動,且一定程度上減少了水波模擬過程中的計算量(約13%),適用于實時性要求較高的系統(tǒng)。
[Abstract]:In this paper, by analyzing the Taylor expansion of trigonometric functions, a method of optimizing trigonometric functions using polynomial functions is proposed, which is used to improve the real-time performance of water wave simulation in virtual systems. In this algorithm, the diversity of water wave waveform is realized by introducing many parameters of control waveform. On this basis, a method of calculating surface normal vectors is proposed to better interact with the surrounding environment and light. The natural water wave image is used as reference, and the performance is compared with the typical algorithms Gerstner and FFT. The experimental results show that the proposed algorithm can generate abundant and natural water wave motion, and reduce the computational cost (about 13%) in the process of water wave simulation to a certain extent, so it is suitable for the system with high real-time performance.
