Digital rubbing manufacturing method and system based on triangular grid model and storage medium

The invention discloses a digital rubbing manufacturing method and system based on a triangular grid model and a storage medium. The method comprises steps of step (1), generating a triangular grid model of an object of a to-be-manufactured digital rubbing and carrying out smoothing processing on a normal vector of each top point of the triangular grid model; step (2), selecting the region of theto-be-manufactured digital rubbing and setting the radius of a virtual robbing pack; step (3), according to the radius of the virtual robbing pack, calculating the height of each top point of regionsof the to-be-manufactured digital rubbing of the triangular grid model, and converting the height value of each top point into a gray scale value; and step (4), according to the gray scale values, carrying out orthographic projection of the regions of the to-be-manufactured digital rubbing into images so as to obtain digital rubbings. 本发明公开了基于三角网格模型的数字拓片制作方法、系统及存储介质，包括：步骤(1)：生成待制作数字拓片的物体的三角网格模型；对三角网格模型的每个顶点的法向量进行平滑处理；步骤(2)
