DipoleTiltDemo.net
Demos the DipoleTilt macro. It transforms the unit vector in z direction in MAG (dipole z-axis) to GSM. To Do: - The mark-compute-unmark shennanagins in the advanced example should be replaced by something more obvious. As written, it is not clear what is being done. |

EarthDemo.net
Demos the Earth macro which is based on the Globe macro from the bnuspack cd. To Do: - Connect seams in Earth so gap does not appear. - Add input options for alternative representations of Earth; find finer-resolution Earth images. Modified-By: R.S. Weigel Date: 03/06/2006 Added Advanced tab that shows how to get alternative representations of Earth. Would prefer to pass key for representation to Earth macro, but StringLists are not allowed in Macros. (Need to hard-wire strings into macro. Do this after list of images is stable.) |

GlobeDemo.net
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 EXAMPLE VPE: SEE ALSO |

MapToSphereDemo.net
MapToSphere is based on Sphere.net in the bonuspack cd. A field, independent of rank, is transformed by warping it onto a sphere as a three-dimensional analog to traditional two-dimensional cartographic (map) projections. The positions component of the field is warped according to the standard cartesian to spherical coordinates transformation equation without changing any of the data values. NO interpolation is performed. The positions are assumed to be in the following order: latitude, longitude and optionally altitude. Latitude is in degrees north (-90 to +90) and longitude is in degrees east (-180 to +180). If an altitude or other third component of the positions vector is present, its values are added to the input radius of the sphere. If the positions are not organized in this fashion, then they will have be transformed prior to invocation. MODULE MapToSphere CATEGORY CISM_DX_Cartography DESCRIPTION Transform a field by warping onto a sphere INPUT data; field; (none); field to be transformed by sphere warping INPUT radius; value list or field or string or string list; {1.0}; INPUT flag; value list or field or string or string list; {0}; 0 = 2d, 1 = 3d OUTPUT sphere; field; field transformed by sphere warping EXAMPLE VPE: SEE ALSO |

Text3DDemo.net
This demo calls Text3D which is essentially the same as LaTeXText.net by J. Hagon except that it does not use or require LaTeX - it only requires an input string. On the base system fonts, only "area" may be used. This demo calls one of the fonts in the directory dx/fonts/urw that are installed as part of CISM_DX. The urw fonts were taken from http://opendx.npaci.edu/bin/urwfonts.tgz. |
