Relief map of Gulf of Mexico with surrounding area.
The map projection is Mercator. Geographic extents: W:-101; E:-79; S:15; N:34.
The 3D relief is taken from reprojected NASA shuttle radar topography data, with the elevation exaggerated. The relief is baked into a 750x712 mesh with 1075373 polys, 539154 vertices (for the main map).
An additional 16-bit bump texture is used for fine-grained detail.
The texture is rendered from color processed NASA satellite images.
Separate b/w texture masks are included for:
- land/ocean areas - rivers and inland water areas - cities - borders
A multi-layered material (3ds Max version only) together with the provided texture masks allows extensive changes to the appearance of the 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.
