## Abstract

A model generation method includes: obtaining sliced text data; obtaining geometric vertex data in accordance with the sliced text data; determining a geometric object in accordance with the geometric vertex data and a preset geometric object parameter; and rendering the geometric object by using a custom material to generate a to-be-printed model. By adopting the method, coordinates of geometric vertexes are extracted from the sliced text data, the geometric object is determined only in accordance with the coordinates of the geometric vertex, and then the geometric object is rendered to generate the model. A computer device and a computer-readable storage medium is also provided.
