Abstract: A computer readable medium and an image processing method implemented by a computer processor, for determining a color value for a given pixel of a current frame. The method comprises: selecting, by the computer processor, coordinates of a sample position within the given pixel of the current frame; determining, by the computer processor, a present color value for said sample position coordinates; blending, by the computer processor, the computed color value with a color value for at least one pixel of a previous frame, the at least one pixel of the previous frame including a pixel related to the given pixel; and storing in a memory the blended color value for the given pixel of the frame. Thus, aliasing may be mitigated by dynamically varying the relative contributions of the past and the present to the rendered color value of pixels in a frame.

Abstract: A computer-implemented method, system and computer-readable medium for determining an illumination component for a selected point in a multi-dimensional space. The method comprises identifying a set of probes associated with the selected point, the probes located in the multi-dimensional space; for each selected one of the probes, determining which of a plurality of zones for the selected probe contains the selected point and determining visibility of said determined zone from the selected probe; and deriving an illumination component at the selected point by combining scene irradiance data associated with those of the probes from which the corresponding determined zone is determined to be visible. The illumination component being determined may be the diffuse component of global illumination as applicable to computer graphics rendering.
