3DField is a 3D contouring and surface-plotting program. It converts your data into contour maps and surface plots. Features include automatic or user-defined contour intervals and ranges; control over the contour label format, font, frequency, and spacing; and automatic or user-defined color for contour lines. It also has color fills between contours, either user-specified or as an automatic spectrum of your choice; the ability to add a color-scale bar; and the ability to print maps in EMF, WMF, BMP, JPEG, and PNG formats. Additional features include an inverse distance-gridding method, a panel bar, multipage scale print, and PNG graphic formatting, and you can now save/open as a 3DField document. Version 2.04 adds a few new shaded relief methods.
