The present disclosure provides a method for processing visibility data of a three-dimensional model performed by a computer device. The method includes: obtaining original values of visibility data of a plurality of sampling points of the three-dimensional model; determining visibility data of a plurality of vertexes of the three-dimensional model based on a first error function measuring differences between recovery values of the visibility data of the sampling points from interpolation of the visibility data of the vertexes of the three-dimensional model and the original values of the visibility data of the sampling points and change rates of the recovery values of the visibility data of the sampling points; and storing the visibility data of each vertex of the three-dimensional model. This method reduces the space for storing the visibility data, relieves the pressure of storing the visibility data, and improves the efficiency of rendering the three-dimensional model.
