A game system comprising:

• one or more processors;
• and
• one or more memories storing instructions to perform operations comprising:
• updating voxel data defined in a virtual space based on game processing, wherein in the voxel data, for each of a plurality of voxels, at least a density indicating the degree of virtual occupation of a content in a space defined by the voxel, and a material indicating the type of the content, are set;
• generating and updating a display mesh related to the voxel data and to be rendered based on a virtual camera, by determining vertex coordinates of the display mesh based on at least the density included in the voxel data, and determining a material of the display mesh based on at least the material included in the voxel data;
