<br>
I've got a shapefile with points. The altitude (Z) of each point is
registered as attribute data.<br>
Is there a way I can obtain a shadowed elevation raster with QGIS ?
I've got a little or no experience with raster processing, but I learn
fast :)<br>

Yes, it's a two step process. First you'll need to interpolate your
point data into a raster to create a DEM. The best way to do that is
with the GRASS plugin, using the v.surf.rst GRASS module. Pay attention
to the raster resolution when you first create your GRASS
location/mapset.<br>
Second, to make the shaded relief surface you can either use the QGIS
plugin "Shaded relief" or you can stay in GRASS and try the
r.shaded.relief module.<br>
<br>
Try these out, and post back if you need more help.<br>
