Bug report #9392

I`m trying to create a sphere-like view using qgis and the "world from space"-projection http://spatialreference.org/ref/sr-org/6980/ (essentialy an ortho-projection). ArcGIS wraps the shapes correctly but QGIS (2.01) produces nasty artifacts.
Currently for this to work you'll need to crop your layer before projecting it: Project your shapefile to an azimuthal equidistant projection with the same parameters as the orthographic projection, create a clipping circle that covers the hemisphere that will be visible in the orthographic projection, and clip the shapefile with that. However, that method requires a fair bit of manual effort, and doesn't work for all projection parameters, since projecting to an azimuthal equidistant projection can lead to similar problems as projecting to an orthographic projection.
