Abstract
A computer graphics system generate a pixel value for a pixel in an image to simulate global illumination represented by an evaluation of an unknown function ƒ of the formg(x) and K(x,y) known functions, with K(x,y) a 'kernel' including a function associated with at least two colors. An estimator generator module generates 'N' estimators ƒ(x) asΘ(x) representing the Heaviside function, ξ, ξ', . . . , ξ, ξ′components of a multi-dimensional strictly deterministic low-discrepancy sequence and “n” a sequence index. A luminance value module generates a luminance value for the point in the scene as the average of the estimator values generated by the estimator generator module. A pixel value generator module uses the luminance value generated for the point in the scene in generating the pixel value.
