Method GetValue

GTE/Mathematics/BasisFunction.h:410–421

Access the results of the call to Evaluate(...). The index i must satisfy minIndex <= i <= maxIndex. If it is not, the function returns zero. The separation of evaluation and access is based on local control of the basis function; that is, only the accessible values are (potentially) not zero.
