Querying other vector and scalar information in VTP files ?

Support
1

Hi,

I have been able to reading VTP files to query their point position and their topology/connectivity in C++. I am calling GetPoint(index) to get the position, I am able to write them out as geometry file and loading them successfully.

Now I wish to get access to additional scalar and vector data in the VTP files e.g. velocity, pressure etc.

What class/function should I read up on that provide access to those information

        <DataArray type="Float32" Name="k" format="appended" RangeMin="0.0028205080889"      RangeMax="12.535236359"         offset="270680"              >
        </DataArray>

Figured it out. I am able to query them via

polyData->GetCellData();

polyData->GetPointData();

Cheers
