This field must have regular connections. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* dimension #!EF #!EF #!I50 #!N specifies the dimension in which the slab should be oriented relative to the input object (the output slab will have the same orientation). The #!F-adobe-times-medium-i-normal--18* n #!EF dimensions of the object can be specified by number (from 0 to #!F-adobe-times-medium-i-normal--18* n #!EF - 1). The first three dimensions can also be specified as #!F-adobe-times-medium-i-normal--18* x #!EF , #!F-adobe-times-medium-i-normal--18* y #!EF , and #!F-adobe-times-medium-i-normal--18* z #!EF , respectively. #!N #!N The default for this parameter is dimension 0 (zero). #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1. The #!F-adobe-times-bold-r-normal--18* dimension #!EF number refers to the ordering of positions in the "connections" component. Thus, #!F-adobe-times-medium-i-normal--18* x #!EF corresponds to 0 only if the positions have been specified as #!F-adobe-times-medium-i-normal--18* x #!EF varies slowest. #!N #!I30 #!N 2. Slab can also be used on deformed grids, in which case the connections do not align with any particular axis. #!N #!I30 #!N 3. Transposing the positions (i.e., with Transpose) does #!F-adobe-times-medium-i-normal--18* not #!EF change the order in the "connections" component. #!I0 #!N #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* position #!EF #!EF #!I50 #!N specifies the position from which the slab is generated. #!N #!N If the specified value is a single integer, the module creates a single field, with the slab oriented in the specified dimension and containing the number of volume elements specified by #!F-adobe-times-bold-r-normal--18* thickness #!EF (see below). #!N #!N If #!F-adobe-times-bold-r-normal--18* position #!EF is a list of integers, the module creates a series of specified slabs, and the default value of #!F-adobe-times-bold-r-normal--18* thickness #!EF is 1 (one). #!N #!N If this parameter is not specified, the output is a series of slabs ( #!F-adobe-times-bold-r-normal--18* thickness #!EF = 1) that begin at every grid position along #!F-adobe-times-bold-r-normal--18* dimension #!EF . #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* thickness #!EF #!EF #!I50 #!N specifies the thickness of the slab (in volume elements). A specified value of 0 (the default when #!F-adobe-times-bold-r-normal--18* position #!EF is a single number) will produce a 2-dimensional slice in a 3-dimensional object. #!I0 #!N #!N #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1. This module performs no interpolation, and only data with regular connections can be slabbed. #!N #!I30 #!N 2. If the input object is already colored, the colors are passed through unaltered. #!N #!I30 #!N 3. If the input object is a volume and the requested slab is much thinner than the input object, the colors for volume rendering may be dim. #!N #!I30 #!N 4. If the data are connection dependent, a request for a slab of #!F-adobe-times-bold-r-normal--18* thickness #!EF = 0 is ill-defined and the module returns an error. #!I0 #!N #!N #!N #!N Components #!N #!N All input components are propagated to the output. #!N #!N Example Visual Programs #!CForestGreen #!N #!N #!F-adobe-courier-bold-r-normal--18* #!N Imide_potential.net #!N RubberTube.net #!N Streamline.net #!N SIMPLE/Slab.net #!EF #!N #!N #!EC #!N #!N See Also #!N #!N #!Lmaptopl,dxall892 h MapToPlane #!EL , #!Lselect,dxall936 h Select #!EL , #!Lslice,dxall950 h Slice #!EL #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lslice,dxall950 h Slice #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
