摘要
In this paper, we present a novel real-time approach to generate high-quality stippling on 3D scenes. The proposed method is
built on a precomputed 2D sample sequence called incremental Voronoi set with blue-noise properties. A rejection sampling
scheme is then applied to achieve tone reproduction, by thresholding the sample indices proportional to the inverse target tonal
value to produce a suitable stipple density. Our approach is suitable for stippling large-scale or even dynamic scenes because
the thresholding of individual stipples is trivially parallelizable. In addition, the static nature of the underlying sequence benefits
the frame-to-frame coherence of the stippling. Finally, we propose an extension that supports stipples of varying sizes and tonal
values, leading to smoother spatial and temporal transitions. Experimental results reveal that the temporal coherence and
real-time performance of our approach are superior to those of previous approaches.
