Gravity disturbance to the first derivative of the potential Īnd the displayed gravity gradient was computed as the second radial derivative of the disturbing potential.įor precise definitions, see the reference paper. Here, geoid height is related to Earth gravity potential and Which is particularly well illustrated in the 3D images.

With only the basic module of Matlab without any toolbox, ♣ Clicking on each image displays it in your browser, clicking on the image title will take you to its Matlab code.Įxamples of using the package rotating_3d_globe.zip. In reality the Earth's shape is very close to a sphere (for more details, see the reference paper). ♣ Variations in geoid height are thousand times exaggerated ("Earth potato"), Originally this package was developed for 3D visualizing the geoid height of new global gravity field models.

In principle, any scalar data given on a grid of longitudes and latitudes can be visualized with this package. Our idea was to offer the reader snippets of the Matlab code for "copy and paste" style of programming. The only prerequisite is to have the basic module of Matlab. We present a free Matlab package rotating_3d_globe.zip, with which you can produce your own 2D and 3D png images,Īnimated gifs, videos or input files for 3D printers.
