[vtkusers] Fwd: Choose the second component in vtkDataArray without copy

[Manh Nguyen]

Dear vtk developers,

I have created this code:

vtkDataArray *DataArray =
reader->GetOutput()->GetPointData()->GetArray("qflow velocities");


The DataArray is an array with 3 components (x,y,z), but by default it read
only the x component?


Is there a way to select only the components without using CopyComponent or
any other copy functions?

 I have tried GetVectors but it crashed. the data just load single Scalars.

Does vtkDataArray have something like get Component Array? or something?

Sincerely,

Tat Manh Nguyen
