NAME

       TDSTRI - Add triangles defining a simple surface to the triangles in a triangle list.

SYNOPSIS

       CALL TDSTRI (U, NU, V, NV, W, LW1D, RTRI, MTRI, NTRI, IRST)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_tdstri(float *u, int nu, float *v, int nv, float *w, int lw1d, float *rtri, int mtri, int *ntri,
       int irst)

DESCRIPTION

       The arguments of TDSTRI are as follows:

       U       (an input array, of type REAL, dimensioned NU) - values of an independent variable "u". It must
               be the case that U(1) < U(2) < ... U(NU-1) < U(NU).

       NU      (an input expression of type INTEGER) - the dimension of U.

       V       (an input array, of type REAL, dimensioned NV) - values of an independent variable "v". It must
               be the case that V(1) < V(2) < ... V(NV-1) < V(NV).

       NV      (an input expression of type INTEGER) - the dimension of V.

       W       (an input array, of type REAL, dimensioned NU x NV and having FORTRAN first dimension LW1D) -
               values of a dependent variable "w(u,v)". The points (((U(I),V(J),W(I,J)),I=1,NU),J=1,NV) define a
               surface that one wishes to draw.

       LW1D    (an input expression of type INTEGER) - the FORTRAN first dimension of the array W.  It must be
               the case that LW1D is greater than or equal to NU.

       RTRI    (an input array, of type REAL, dimensioned 10 x MTRI) - a list of triangles, probably created by
               means of calls to TDSTRI, TDITRI, and/or TDMTRI, and sorted, probably by means of a call to
               TDOTRI.

       MTRI    (an input expression of type INTEGER) - the second dimension of RTRI and thus the maximum number
               of triangles the triangle list will hold.

       NTRI    (an input/output variable of type INTEGER) - keeps track of the number of triangles currently in
               the list.  It is the user's responsibility to zero this initially and its value is increased by
               each call to a triangle-generating routine like TDSTRI. If NTRI becomes equal to MTRI, TDSTRI
               does not take an error exit; instead, it just stops generating triangles.  Therefore, it's a good
               idea, after calling TDSTRI, to check the value of NTRI against the dimension MTRI; if they're
               equal, it probably means that the triangle list filled up and that the rendered surface will be
               incomplete.

       IRST    (an input expression of type INTEGER) - specifies the index of the rendering style to to be used
               for the triangles added to the triangle list by this call.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

ACCESS

       To use TDSTRI or c_tdstri, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.
