I can only second that. A convenient way to write a new interpolation
function is to derive a subclass from QgsInterpolator
(src/analysis/qgsinterpolator.h). Interpolation usually requires a lot
of computation, therefore it is good to implement it in the analysis
library in C++. Like that, the method is available to QGIS and its
plugins (also python) and other applications using QGIS libs.

Hello all,
I was browsing through the plugin ideas to work on something, and
this
http://hub.qgis.org/wiki/quantum-gis/Python_Plugin_Ideas#heatmaps-reusable-python-code
particular plugin idea seemed to be a good start.
Heatmaps would be great because currently, it's always necessary to
start GRASS to do something like that.
Can you write it in C++ to go into core?
Is anyone already working on it? Otherwise I will take it up.
The page contains just the link. It would be great if more
information is provided like, use scenario, what it is exactly
supposed to do? The Input is of course a gpx file, with the
available code, what should be produced as the output in Qgis? Any
information regarding this is welcome.
The input should be any point layer file. Output should be a raster
layer. A lot of usable code should be contained in the interpolation
plugin which works in this way.
Looking forward to having this functionality in QGIS.
Regards,
Anita
