The set contains three models: a 3D relief map of Japan with surrounding area, a separate 3D relief cutout of the state area, and a separate plain cutout
of the state outline.
The map projection is Lambert Conic Conformal 130/35/20/50. Geographic extents: W:127; E:150; S:28; N:48.
The 3D relief is taken from reprojected NASA shuttle radar topography data, with the elevation exaggerated.
The 3D relief is baked into a 870x1000 mesh with 1747630 polys, 875711 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, urban areas, rivers and water areas.
Texture resolution is 6000 x 6895 pixels, corresponding to approx. 0.5 km per pixel.
Separate b/w texture masks are included for:
- state area
- state exterior
- land/ocean areas
- rivers and inland water areas
- urban 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, or different colorings for
the state area and the surroundings.
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.
