[vtkusers] Is it possible to convert data coordinates to world coordinate system?

[chasank]

Hi all,

It's possible to convert a point in world coordinate system to data
coordinate system with the following formula;

for (int i = 0; i <= 2; i++)
    {
        // Transforming world coordinates into data coordinates
        dataCoordinates[i] = static_cast< int >(( worldPoint[i] - origin[i]
) / spacing[i] + 0.5 );
    }

However I need a reverse conversion from data coordinate system to world
coordinate system?
Is it possible? if yes how?
Thanks
