3D New York City USA

New York City, NYC, Manhattan (USA) (2013) 3D Model for 3ds Max, Maya, Cinema 4D, Lightwave, Softimage, Blender and other 3D modeling and animation software.

Updated 12 February 2013: This 3D model in projected spatial NAD83 UTM zone 18N planar Cartesian metric coordinates centered on XY-plane with Z-axis points up. Centering on XY-plane is required for correct rendering and animation to prevent z-buffer floating point precision inaccuracy for every camera angle, zoom and position.

To get true North American Datum 1983 Universal Transverse Mercator Zone 18N SRID 26918 coordinate reference system based on the WGS84 datum for calculations, if needed, simply 2D transform every vertex X coordinate by 583217,815782511 and every vertex Y coordinate by 4506488,6095344.

All vertices in 64-bit double-precision floating-point format with correct DEM for ground elevation data and with correct buildings heights and positions.

Entire scene bounds (in GPS coordinates):

Top-Left corner (-74,02587890625 / 40,6972990086367),

Bottom-Right corner (-73,927001953125 / 40,8470603560712).

0.3 meters per pixel ground textures resolution.

.OBJ is native file format for this 3D model.

3D Model was built with my custom software using DEM elevation data map and building positions. Model textured using free ground textures available on internet.

4096x4096 ground patches and buildings textures resolution.

Model includes: Battery Park, Castle Clinton National Monument, Robert F Wagner Jr Park, New York Stock Exchange, South Street Seaport, South Cove, NY Downtown Hospital, World Financial Centers, Esplanade, City Hall Park, City Hall, New York Mercantile Exchange, North Cove, Thomas Paine Park, Columbus Park, Governor Nelson a Rockefeller Park, Washington Market Park, Tribeca, Chinatown, Brooklyn Bridge, Schermerhorn Row and more buildings.
