readPoints
Reads the non-central points from a appropriate span of columns in a supplied tuple. The central data position must be supplied as input. TheicExtra
value gives the column corresponding to the first coord of this coordinate set in the sequence; the following few columns are assumed to correspond 1:1 to the coords in this coord set.- Parameters:
tuple
- tupleicExtra
- index of tuple field corresponding to the first of the coordinates in this setdpos0
- nDataDim-element array giving central data positiondposExtras
- [nPointCount][nDataDim]-shaped array into which the non-central data positions will be written- Returns:
- true iff the conversion was successful
