Detailed Description

This implicit function reads data from a file and produces function values from the data read. The data lies on a rectilinear grid where the number of grid points in each direction, the spacing, and the origin are specified (by the user or in the file). Function values within the data region are obtained using trilinear interpolation. Function values outside the data region are the maximum value of the data read.

The data can be read from standard input or a named file. The data can have no header, an ASCII header containing the number of grid points in each direction:

     numX numY [numZ]

or an ASCII header containing the above information followed by the data spacing in each direction and the origin of the data - both in physical coordinates:

     deltaX  deltaY  [deltaZ]
     originX originY [originZ]

Following any header is the data either in ASCII or binary. The data is assumed to vary most rapidly in the x coordinate, then the y coordinate, and, finally, in the z coordinate (for 3D data).
