Abstract

The invention discloses a spherical terrain construction method which comprises the following steps: S1, binding all visible elements on a map with cells where the visible elements are located, and carrying out parallel calculation on the visible cells by using a GPU (Graphics Processing Unit) and carrying out visible marking; s2, rendering information of the visible cells is put into corresponding list pools according to model rendering types; and S3, rendering all the list pools with the content. The method has the beneficial effects that the model elements are bound with the cells, the visible cells are calculated by using the GPU, so that real-time editing and modification are facilitated, and a spherical grid generation technology and a triangular rendering unit geometric fusion technology are combined, so that the visual angle height and the cells with millions of magnitudes can be switched at will.
