摘要: In flow visualization, integral surfaces rapidly tend to expand, fold and produce vast amounts of occlusion. While silhouette enhancements local transparency mappings proved useful for semi-transparent depictions, they still introduce visual clutter when grow more complex. An effective visualization the requires a balance between presentation interesting surface parts avoidance occlusions that hinder view. this paper, we extend concept opacity optimization obtain global approach occlusion problem. Starting with partition into patches, compute per-patch as minimizer bounded-variable least-squares For final rendering, is interpolated on surfaces. The resulting technique interactive, frame-coherent, view-dependent driven by domain knowledge.
