The invention discloses a high-frequency material rendering method and system based on a micro-surface theory. The method comprises the steps of: extracting the high-frequency geometrical characteristics of a to-be-rendered high-frequency material; reconstructing the position distribution and the normal distribution of the high-frequency geometrical characteristics to obtain a high-frequency material model; fitting the high-frequency material model; and rendering the fitted high-frequency material model to obtain a rendered high-frequency material. 本发明公开了基于微表面理论的高频材质渲染方法及系统，包括：对待渲染的高频材质，提取高频几何特征；对高频几何特征的位置分布和法向分布进行重构，得到高频材质模型；对高频材质模型进行拟合；对拟合后的高频材质模型进行渲染，得到渲染的高频材质。
