The set contains three models: a 3D relief world map, a separate 3D relief cutout of the land area, and a separate plain cutout
of the land outline.
The map projection is Mercator. Geographic extents: W:-180; E:180; S:-80; N:84.
The 3D relief is taken from reprojected NASA shuttle radar topography data, with the elevation exaggerated.
The 3D relief is baked into a 750x641 mesh with 967172 polys, 484996 vertices (for the main map).
An additional 16-bit bump texture is used for fine-grained detail of the 3D relief.
The texture is rendered from color processed NASA satellite images. Included are borders, major cities, rivers and water areas.
Separate b/w texture masks are included for:
- land/ocean areas
- rivers and inland water areas
- ocean floor depth
A multi-layered material (3ds Max version only) together with the provided texture masks allows extensive changes to the appearance of the 3D relief map.
Possible customizations include different colorings or complete removal of separate features like cities or borders.
A description of the multi-layered material and texture masks can be found in the accompanying PDF-manual.
Previews are rendered with mental ray, but the project uses only standard materials.
The .obj and .fbx versions will require new texture assignments after import.
The .obj format is exported as triangles.
The compass rose is included as a bonus.
