#!EF #!N #!N Functional Details #!N #!N This module determines which
points in a data set are to be treated as valid
by other modules. It does so by removing or invalidating data
values that fall within (or outside) a specified range, thereby #!F-adobe-times-medium-i-normal--18*
including #!EF the remaining points in the set. If there are
connections (or faces or polylines) in the field, and #!F-adobe-times-bold-r-normal--18* pointwise
#!EF =0, then Include also removes all invalid connections (connections containing
at least one invalid position) and all unreferenced positions (positions not
referred to by any valid connection, face, or polyline element). #!N
#!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* data #!EF #!EF #!I50
#!N is the data field that the module operates on. #!N
#!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* min #!EF #!F-adobe-times-medium-r-normal--18* and #!EF #!F-adobe-times-bold-r-normal--18* max
#!EF #!EF #!I50 #!N specify a range of data values whose
function is determined by the #!F-adobe-times-bold-r-normal--18* exclude #!EF flag (see below).
#!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* exclude #!EF #!EF #!I50 #!N specifies
whether the values to be excluded from the data set lie
within or outside the range defined by #!F-adobe-times-bold-r-normal--18* min #!EF and
#!F-adobe-times-bold-r-normal--18* max #!EF . #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30
#!N o 0: Removes or invalidates all elements or positions whose
data values lie #!F-adobe-times-medium-i-normal--18* outside #!EF the specified range. #!N #!I30
#!N o 1: Removes or invalidates all elements or positions whose
data values lie #!F-adobe-times-medium-i-normal--18* within #!EF the specified range. #!N #!I0
#!N #!EF #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* cull #!EF #!EF
#!I50 #!N specifies whether the excluded (culled) points are to be
invalidated or actually removed from the data set. #!N #!I0 #!N
#!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N o 0: Returns the field with
invalid positions and invalid connections, invalid faces, or invalid polylines components.
Since it is unnecessary to remove invalid positions, connections, faces, or
polylines, in order to have them treated as invalid by other
modules, this is usually the preferred setting. #!N #!N If the
module removes points from data with regular connections (e.g., cubes or
quads), the connections become irregular. #!N #!I30 #!N o 1: Returns
the field with invalid positions and connections removed. #!N #!I0 #!N
#!EF #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* pointwise #!EF #!I50 #!N if
set to 1, the connections of #!F-adobe-times-bold-r-normal--18* data #!EF are removed
before the points are selected. #!I0 #!N #!N See #!Linval,dxall211 h Invalid Positions and Invalid Connections Components #!EL in
IBM Visualization Data Explorer User's Guide for further discussion of invalid
data. #!N Note: If #!F-adobe-times-bold-r-normal--18* data #!EF is a vector field
and #!F-adobe-times-bold-r-normal--18* min #!EF and #!F-adobe-times-bold-r-normal--18* max #!EF are: #!N #!I0
#!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N o scalars, then the module
uses #!F-adobe-times-bold-r-normal--18* min #!EF and #!F-adobe-times-bold-r-normal--18* max #!EF to exclude points
whose magnitudes fall inside (or outside) the limits. #!N #!I30 #!N
o vectors matching the shape of the data field, then only
those vector values lying between the corresponding limits are retained. #!N
#!N For example, if the data are 3-D vectors, the values
retained are those for which min[x] ó data[x] ó max[x] and
min[y] ó data[y] ó max[y] and min[z] ó data[z] ó max[z]
are retained (assuming #!F-adobe-times-bold-r-normal--18* exclude #!EF = 0). #!N #!I0 #!N
#!EF #!N #!N #!N #!N Components #!N #!N Modifies the "data,"
"positions," and "connections" components and any components that depend on "positions"
or "connections." Adds an "invalid positions," "invalid connections," or "invalid faces"
component if #!F-adobe-times-bold-r-normal--18* cull #!EF is set to 0. Removes the
"connections" component if #!F-adobe-times-bold-r-normal--18* pointwise #!EF is set to 1. All
other components are propagated to the output. #!N #!N Example #!N
#!N In the following example, the gradient of the electron density
has been mapped onto an isosurface. The Include module removes all
points whose data values are greater than 1.5. #!CForestGreen #!N #!N
#!F-adobe-courier-bold-r-normal--18* #!N electrondensity = Import("/usr/lpp/dx/samples/data/watermolecule"); #!N electrondensity = Partition(electrondensity); #!N gradientdensity
= Gradient(electrondensity); #!N maggradient = Compute("mag($0)", gradientdensity); #!N isosurface = Isosurface(electrondensity,
0.3); #!N mappediso = Map(isosurface, maggradient); #!N camera = AutoCamera(isosurface); #!N
included = Include(mappediso, 0, 1.5); #!N Display(included, camera); #!EF #!N #!N
