1. A machine-implemented method of graphics processing, comprising:
determining, at a position in a scene, an extent of occlusion from a light by
determining a glancing ray which, of a plurality of rays cast from said position towards different points within the light, is the closest ray to an occlusion which is not occluded by the occlusion; and
using an angle between the determined glancing ray and a ray cast towards a predefined point on the light to determine the extent of occlusion at said position in the scene from the light.
