whether

Note: Weighted sums can only be performed on
a single element, and thus
don't have a generic GA_AttributeOperand method.
@param d The destination attribute
@param di The index in the destination attribute used to store results
@param sum Weighted sum to keep track of partial sums
virtual bool startSum(GA_Attribute &d, GA_Offset di,
const GA_WeightedSum &sum) const = 0;
Add an element into the weighted sum
@param d Destination attribute
@param di Destination offset
@param sum Storage for state of weighted sum
@param a Attribute to add into the sum
@param ai Index of the attribute to add into the sum
virtual bool addSum(GA_Attribute &d, GA_Offset di,
const GA_WeightedSum &sum,
const GA_Attribute &a, GA_Offset ai) const = 0;
Add the square of an element to the weighted sum
@param d Destination attribute
@param di Destination offset
@param sum Storage for state of weighted sum
@param a Attribute to add into the sum
@param ai Index of the attribute to add into the sum
virtual bool addSquare(GA_Attribute &d, GA_Offset di,
const GA_WeightedSum &sum,
const GA_Attribute &a, GA_Offset ai) const = 0;
Finish a weighted sum. The scale_factor can be used to normalize
weighting. For example: @code
endSum(d, di, sum, 1./sum.getTotalWeight());
