void FlowData::getPosition ( float *  aPosition,
float *  aWeightResult,
int *  anIndexToWeight 
) [private]

casculates the weights of nearest values to interpolate a position based on the fact that the given positions form a grid with no holes xPos(x(i)y(j)) == xPos(x(i)y(k)) yPos(x(i)y(k)) == yPos(x(j)y(k)) will not work otherwise

Parameters:
