You could use vtkProgrammableSource to manually parse your data yourself and place it into the appropriate VTK data structure. The vtkDataReader classes are intended for reading specific file format. If your legacy format is not one of those currently supported by VTK, you'll have to just parse through the data yourself. As you parse through the data, you can then insert it into VTK's data structures.

If you know that you're reading 3D points, you can read the values and place the points in a vtkUnstructuredGrid. Other data such as scalars or colors can be associated with this data.
