This engine joins up to 10 separate fields of a type into a single multiple-valued field of the same type. The type of the input fields can be any subclass of
SoMField The type is specified when an instance of
the class is created. For example,
SoConcatenate(SoMFFloat::getClassTypeId()) creates an engine that concatenates floating-point values.
The
input field is a 10-element array, where each element can be connected to single- or multiple-valued fields.
All the values in the input are concatenated together to form one multiple-value field. For example, if
input[0] contains 10 values and
input[1] contains 3 values, the output will contain 13 values.
Note that, unlike
the output of most engines,
output is a pointer. Note also that by default
input does not contain any values, and no value is output from the engine.
