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.<br>

I was browsing through the plugin ideas to work on something,
and this <a moz-do-not-send="true"

target="_blank">http://hub.qgis.org/wiki/quantum-gis/Python_Plugin_Ideas#heatmaps-reusable-python-code</a>
particular plugin idea seemed to be a good start. <br>

Is anyone already working on it? Otherwise I will take it up.<br>
<br>
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.<br>

<div>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.</div>
<div><br>
</div>
<div>Looking forward to having this functionality in QGIS.</div>
