AsdGraph3D is an OpenGL-based Excel Addin that plots 3D scattered points,
lines, surfaces or water tight solids directly from user-specified cell
ranges within MS Excel worksheets (from one or several open workbooks).
Version 1.1 adds ability to control how values of empty cells are assigned
or interpolated based on adjacent cells in an Excel worksheet. For detailed
information, please visit AsdGraph3D home page: http://activesolid.ncf.ca/asdgraph.html
