Demos the Globe macro from the OpenDX bonuspack cd. It creates a globe of the earth by taking a two-dimensional scalar field of the earth's topography (altitude above/below sea level), which has been cleverly colored, and warp it onto a sphere. The topography may be either mapped to a pseudo-color or gray scale. For the former, the color map has all values around and below 0 (as sea level) colored light blue, which increases in darkness with depth. For the latter, the gray scale map has all values around and below 0 (as sea level) colored gray, which increases in darkness with depth. Optionally, the globe may be radially deformed by topography to create a "bumpy" globe.

MODULE Globe CATEGORY Cartography DESCRIPTION Create an object, which represents an earth globe INPUT globe_type; integer; 1; 1 = smooth globe, 2 = "bumpy" globe INPUT reduction; scalar list or vector list; {1}; factor (power of two) to reduce resolution of topography from .5 degree INPUT color; integer; 1; "coloring" of topography: 1 = pseudo-colored, 2 = gray-scale OUTPUT globe; field; globe of the earth
