1. A method, comprising:
iteratively evaluating convergence of pixels of a rendering by removing texture from the rendering to eliminate non-convergence due to texture complexity and determining whether pixel values satisfy convergence criteria associated with pixel sampling and sampling those pixels of the rendering that have not converged with one or more additional samples during each iteration; and
outputting the completed rendering, wherein pixels of the completed rendering satisfy the convergence criteria and wherein pixels of the completed rendering are not uniformly sampled.
