The set contains three models: a 3D relief map of Iceland 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 Azimuthal Equal-Area -20/65. Geographic extents: W:-26.5; E:-10.0; S:62; N:68.0.
The 3D relief is taken from reprojected NASA shuttle radar topography data, with the elevation exaggerated. The 3D relief is baked into a 750x679 mesh with 1024258 polys, 513566 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 cities, rivers and water areas.
Separate b/w texture masks are included for:
- land/ocean areas - rivers and inland water areas - cities - 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.
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.
