+In this image we see the raw result of the raycasting in the SSAO shader. This should be blurred te remove the approximation artifacts.
+This will be implemented by first creating a Gaussion blur filter, which is also needed for [[documentation:rendering:hdr|HDR]].
+Many sources recommend using a bilateral blur filter. This post (http://www.gamedev.net/community/forums/topic.asp?topic_id=587178&PageSize=25&WhichPage=2) talks about creating a bilateral filter.
+This presentation (http://developer.amd.com/gpu_assets/ShopfMixedResolutionRendering.pdf) also gives much information on filtering, including shadowmap filtering.
