In this paper, the contour of the template is constructed by OpenGL function and cubic NURBS curve, and the shape of the curve is modified by adjusting the NURBS weight factor. Source data, W meets the proposed demand for any human body and clothing. In the specific application scenario of this paper, the 3D simulation model establishment part is divided into grid model establishment, real-time lighting simulation and 3D virtual simulation design effect display module. This digital design method implements the WYSIWYG design concept. It can realize the sharing of high-quality teaching resources, interactive learning and teaching evaluation, and provide a reference plan for the construction of higher vocational teaching resources cloud platform.
