Leo Talbot and Carol O'Sullivan, 'Analysis of visibility masks and resultant image quality' in proceedings of the EUROGRAPHICS workshop on Parallel Graphics and Visualization, Girona, Spain, 2000, pp 75 - 80.
Virtual Interfaces and Visibility Masks are an extremely efficient
method for parallelising the Radiosity Method. They exploit data locality, and
keep communication between nodes as low as possible. Previous papers on this
technique have been mainly concerned with raw performance, and have failed
to analyse how these techniques can impact on the quality of the final image.
This paper explores the efficiency of generating visibility masks, and analyses
the tradeoff between image quality and speed.
