Hi all.
I tested the interpolation plugin against the equivalent gdal tool (grid). The
results are comparable (which is good; obviously the C++ plugin is way faster), but
the two resulting rasters are slightly different: the C++ result seems shifted
slightly to NW, while the gdal seems more centered on the actual points. maye
computation is done on the NE corner instead of the center of the grid?
I can provide the two resulting tiffs and a sample point shp if it helps.
All the best.
