Yes, exactly.
I am using DTM to calculate pipe slopes. If you have very short pipes
crossing two raster cells, you will get a wrong value, this is why I
needed to calculate interpolated values.
You can choose:
- nearest neighbor
- bi-linear using 4 cells
- bi-cubic using 16 cells (I did not notive slow down, but it requires
scipy)
Also, the plugin saved directly the values in the vector layer (instead
of creating a new shapefile).
Cheers,
Denis

Foreach point feature of the vector layer:
- take the location of the point
- calculate an interpolated value of a chosen band at the point location
you mean, it is interpolating between adjacent cells? This is interesting, and I
believe quite new.
thanks.
