[vtkusers] How to import NASA SRTM DEM data into VTK

[Michael Jackson]

Actually you will want to over ride RequestInformation and  
RequestData() methods. The other 2 methods I think were for the older  
4.x pipeline and are there for historic reasons... I think.

RequestInformation and RequestData are the correct methods to over ride.


Take a look at:

vtkH5PhaseFieldReader for an example reader.
