[Qgis-developer] Interpolation plugin

[Tim Sutton]

Hi Marco

Cool stuff! I tried to compile but the CMakeLists.txt seems to be
missing from your tarball.

Regards

Tim

> (ascii grid format by now) from a vector layer using linear triangulation or
> inverse distance weighting. The plugin code is here:

> To compile, unpack in src/plugins directory and add 'interpolation' to the
> first line in src/plugins/CMakeList.txt:
>
>  SUBDIRS (copyright_label delimited_text grid_maker north_arrow scale_bar
> interpolation)
>
> The code for triangular interpolation originates from my phd several years
> ago. There are some capabilities that are provided by this code which are not
> accessible through the plugin GUI yet:
> - cubic triangular interpolation (clough-tocher methode or coons patch)
> - modify the delaunay triangulation by swapping edges
> - mark input data as constrained triangle edges or breaklines
>
>
> The interpolation plugin is generic enough to support other type of
> interpolation methods. If you want to see your favorite interpolation method
> in QGIS, all you have to do is to provide a subclass of QgsInterpolator and a
> subclass of QgsInterpolatorDialog that takes the parameter for the
> interpolation method.
