3DField is a contouring surface plotting and 3D data program that runs under Microsoft Windows 95/98/2000/XP. 3DField converts your data into contour maps and surface plots. All aspects of 2D or 3D maps can be customized to produce exactly the presentation you want.

When I tried using with SRTM data from Antyong, it's look OK(must study more...
but can get 3D IMAGE perfectly). FauSham Rating:
/10 similies value 
We can use any of this file with 3DField:

POI (Point-Of-Interest for this software):
#4D project 3DFieldPro new version:
- Volume gridding for 4D scattered points by 4 gridding methods;
- Create isosurfaces and 3D planes;
- 3D model with irregular grid;
- All options of 3DField.
# 7 gridding methods (Radial Basis Functions, Inverse Distances, Triangulation, Kriging, Minimum Curvature, Natural Neighbors, Linear System )
# Automatic or user-defined contour intervals and ranges
# Control over contour label format, font, frequency and spacing
# Automatic or user-defined color for contour lines
# Color and texture fill between contours, either user-specified or as an automatic spectrum of your choice
# Base map attached to data points
# Data analysis, histogram for scatered points and interpolated grid values
# Regression 2D data
# Splines for lines and contours
# View and zoom BMP, GIF, PNG, JPG, TIFF and GeoTIFF images
# Automatically and manually digitize image
# Import and export lines
# Ascending or descending sort for values or coordinates of points
# OpenGL view with full screen rotation.
# Textures
# Convert a contour bitmap to a 3D view
# Output maps as EMF, WMF, BMP, JPG, PNG, GeoTIFF file formats
# Insert maps (EMF or bitmap) in any document Microsoft Office
# Multipage scale print
# Multilingual interface
& then transfer it into Nuvi?????
