【摘要】 介绍了一般浓淡光照模型的分析方法,通常评价一个光照模型是从直观上看其视觉效果,因此,需要一种方法来分析浓淡模型函数,以便预测到一个函数的光照效果,并在所使用的不同函数之间进行比较,同时根据所选择理论基础和实验的结果判断它们的正确性,文中阐述光照模型的分析方法及估测效果,用一种新的方法计算Fresnel函数的近似值,它较线性内插具有更高的逼真度。更多还原

【Abstract】 This paper introduces the analysis methods of the general shading illumination models. Usually, what we justify an illumination model is to watch the visual effectiveness. Therefore, we need a method to analysis the model functions, so that we can predict the illumination effectiveness and compare these the different model functions. At the same time, we could justify the correctiveness by the selected theory basis and the experiment result. The analysis methods and the estimating results are also described, it is more realistic than the general interpolation method by using the new method to calculate the approximate value of Fresnel function.更多还原
