class UPCGAttributeReduceSettings : public UPCGSettings
Remarks
Take all the entries/points from the input and perform a reduce operation on the given attribute/property and output the result into a ParamData. Note: Special case for average on Quaternion since they are not trivially averageable. We have a simplistic approximation that would be accurate only if the quaternions are close to each other. The accurate version of the average is using eigenvectors/eigenvalues which is way more complicated and computationally expensive. Quaternion will also be normatilzed at the end. Beware if you are using this average.
