.SH NAME
DSGRID3D - double precision Fortran entry for 3D gridding
.SH SYNOPSIS
CALL DSGRID3D (NPNTS, X, Y, Z, U, NUMXOUT, NUMYOUT, NUMZOUT, 
.br
XO, YO, ZO, UO, IER)
.SH DESCRIPTION
.IP NPNTS 12
(Integer, Input) - The number of input data points.
.IP X 12
(Double precision, Input) - An array containing the X 
coordinates of the input data points.
.IP Y 12
(Double precision, Input) - An array containing the Y 
coordinates of the input data points.
.IP Z 12
(Double precision, Input) - An array containing the Z 
coordinates of the input data points. 
.IP U 12
(Double precision, Input) - An array containing the functional 
values of the input data points. 
That is, U(L) is the value of the input function at coordinate 
(X(L),Y(L),Z(L)), for L=1,NPNTS. 
.IP NUMXOUT 12
(Integer, Input) - The number of X values in the output grid.
.IP NUMYOUT 12
(Integer, Input) - The number of Y values in the output grid.
.IP NUMZOUT 12
(Integer, Input) - The number of Z values in the output grid.
.IP XO 12
(Double precision, Input) - An array of dimension NUMXOUT containing the X 
coordinates of the output data grid. The values in XO must be 
increasing, but need not be equally spaced. 
.IP YO 12
(Double precision, Input) - An array of dimension NUMYOUT containing the Y 
coordinates of the output data grid. The values in YO must be 
increasing, but need not be equally spaced. 
.IP ZO 12
(Double precision, Input) - An array of dimension NUMZOUT containing the Z 
coordinates of the output data grid. The values in ZO must be 
increasing, but need not be equally spaced. 
.IP UO 12
(Double precision, Output) - A three-dimensional 
array dimensioned as UO(NUMXOUT,NUMYOUT,NUMZOUT)
containing the interpolated functional values. UO(I,J,K) is the 
interpolated value at grid point (XO(I),YO(J),ZO(K)). 
.IP IER 12
(Integer, Output) - An error return value. If IER is returned as 0, then
no errors were detected. If IER is non-zero, then refer to the man
page for dsgrid_errors for details.
.SH USAGE
DSGRID3D is the single precision gridding function in the Dsgrid package.
The behavior of DSGRID3D is controlled by values set for the various
parameters described in dsgrid_params.  Values for these parameters
can be set using the subroutines DSSETI, DSSETRD, and DSSETC.
.SH ACCESS
To use DSGRID3D, load the NCAR Graphics library ngmath.
