DESCRIPTION
This engine selects a single value from a multiple-value field, based on
the input field index. The type of the input field can be any subclass of
SoMField, and the type of the output is the corresponding subclass of
SoSField. For example, if the input type is SoMFVec3f, the output type
will be SoSFVec3f. The type is specified when an instance of the class is
created. For example, SoSelOneCreate(SoMFloatGetClassTypeId()) creates
an engine that selects one floating-point value.
Note that unlike most other engine fields, the input field and output are
pointers. Note also that by default input does not contain any values,
and no value is output from the engine.
INPUTS
SoSFInt32 index
Index of the value to select from the multiple-value field.
<inputType> input
The multiple-value field from which the value will be selected.
OUTPUTS
(<outputType>) output
The single value selected.
FUNCTIONSSoSelectOne * SoSelOneSoSelOneCreate(SoType inputType)
Constructor. The argument specifies the type of the multiple-value
input field.
