Method for generating a view of a three-dimensional environment on a set of communication terminals based on a model of the environment that is stored on a server in the form of a grid of voxels, this server implementing steps ofpartitioning (S1) the grid into a set of sub-grids;generating (S2) a surface mesh for each sub-grid;for each sub-grid, simplifying (S3) a sub-part of the mesh excluding an edge area of the mesh; and creating a table associating each vertex of the edge with a voxel;assembling (S4) the meshes of the sub-grids, using this table, in order to form a global surface mesh;transmitting (S5) the global surface mesh to the communication terminals, and generating (S6) a view of the three-dimensional environment based on the global surface mesh and on a point of view associated with each of the communication terminals.
