Belorussian language -- an introductoin of ZeGraph in Belorussian language.
CGER METEX -- a freeware developed by the Jiye Zeng for air trajectory calculation.
Lua -- the first scripting language adopted by ZeGraph.
C-Talk -- another script language adopted by ZeGraph.
OpenGL -- the rendering engine of ZeGraph.
paintlib -- used by ZeGraph to load and save images.
Cximage -- now ZeGraph uses this library to load and save images.
libtif -- a dependent library of paintlib for TIFF image IO.
JPEG library -- a dependent library of paintlib for JPEG image IO.
libpng -- a dependent library of paintlib for PNG image IO.
zlib -- used by paintlib to compression PNG image.
SFL -- The Standard Function Library by iMatrix.
TNT -- ZeGraph uses the Template Numerical Toolkit to solve linear algebra equations.
CEPHES -- math library used by ZeGraph for statistics and special functions.
NetCDF -- an interface for array-oriented data access used by ZeGraph.
HDF -- a library for scientific data management used by ZeGraph.
GSHHS -- the place to download global coastline data.
ETOPO -- NOAA' web site for global relief data. Here is another site for ETOPO data (resulted from google search of "netCDF etopo60").
Free geo-data --has many links for GIS related data.
Virtual Terrain Project -- the earth's image used in the tutorials is from the web site. It has many links to other data resources.
