Abstract:
Graphics processing systems can include lighting effects when rendering images. “Light probes” are directional representations of lighting at particular probe positions in the space of a scene which is being rendered. Light probes can be determined iteratively, which can allow them to be determined dynamically, in real-time over a sequence of frames. Once the light probes have been determined for a frame then the lighting at a pixel can be determined based on the lighting at the nearby light probe positions. Pixels can then be shaded based on the lighting determined for the pixel positions.

Claim (Index 11):
The machine-implemented method of  claim 1 , wherein said tracing one or more rays for a probe position comprises selecting a respective one or more directions for the one or more rays, wherein the selection of a direction for a ray is based on a selection scheme wherein the directions are selected from a set of available ray directions, wherein at least:\n (i) the selection scheme is a round robin scheme; or (ii) the selection scheme is biased towards selecting directions which are towards regions of relatively high luminosity in the scene; or (iii) the direction for a ray is selected from the set of available ray directions based on the respective intervals since the available ray directions were most recently selected for the probe position; or (iv) the direction for a ray for a particular probe position is selected based on directions selected for nearby probe positions; or (v) the selection scheme is biased towards selecting directions which are known to be more significant based on changes to the scene; or (vi) the direction is computed by evaluating a low discrepancy sequence; or (vii) the direction is computed using a quasi-monte-carlo method; or (viii) the direction is chosen because of the position of a known lit scene element or light source.
