#!N #!Rdxni DXNewInterpolator #!N #!N Function #!N #!N Creates
an Interpolator Object for interpolating in Object #!F-adobe-times-bold-r-normal--18* o #!EF .
#!N #!N Syntax #!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h> Interpolator DXNewInterpolator(Object o, enum
interp_init init, float fuzz) #!EF #!N #!N Functional Details #!N #!N
#!N Object #!F-adobe-times-bold-r-normal--18* o #!EF should be a Field or an
Object that contains Fields (e.g., a Group). An Interpolator builds and
stores the information about the Field or Fields to speed up
searching for and computing data values corresponding to any location enclosed
by the positions of the Object. This is particularly useful with
irregular meshes. #!N #!N The initialization type is specified by setting
the #!F-adobe-times-bold-r-normal--18* init #!EF argument to #!F-adobe-times-bold-r-normal--18* INTERP_INIT_DELAY #!EF , #!F-adobe-times-bold-r-normal--18*
INTERP_INIT_IMMEDIATE #!EF or #!F-adobe-times-bold-r-normal--18* INTERP_INIT_PARALLEL #!EF . #!F-adobe-times-bold-r-normal--18* INTERP_INIT_DELAY #!EF does
not initialize the Interpolator until the information is actually needed. This
is fastest if a small number of points will be interpolated.
#!F-adobe-times-bold-r-normal--18* INTERP_INIT_IMMEDIATE #!EF does all initialization before returning. #!F-adobe-times-bold-r-normal--18* INTERP_INIT_PARALLEL #!EF
does all initialization in parallel if running in a multiprocessor machine
before returning. #!N #!N The #!F-adobe-times-bold-r-normal--18* fuzz #!EF value assigns a
fuzz factor to the interpolation process: any sample falling within this
distance of a valid primitive of the Object #!F-adobe-times-bold-r-normal--18* o #!EF
is assumed to be inside that primitive. When this point lies
geometrically outside the primitive, an appropriate result is extrapolated. Any positive
or zero value is used as the fuzz factor; a negative
value indicates that the interpolator should determine its own fuzz factor.
#!N #!N Interpolators can be used with the #!F-adobe-times-bold-r-normal--18* DXMap #!EF
call. See #!Ldxmp,dxall1303 h DXMap #!EL for additional details. #!N #!N The interpolator created
can be deleted with DXDelete. See #!Lmemng,dxall1023 h Memory Management #!EL . #!N #!N Return
Value #!N #!N Returns the Interpolator or returns #!F-adobe-times-bold-r-normal--18* NULL #!EF
and sets an error code. #!N #!N See Also #!N #!N
