Opacity optimization for 3D line fields

摘要: For the visualization of dense line fields, careful selection lines to be rendered is a vital aspect. In this paper, we present global approach that based on an optimization process. Starting with initial set covers domain, all are varying opacity, which subject minimization bounded-variable least-squares problem. The strives keep balance between information presentation and occlusion avoidance. This way, obtain view-dependent opacities segments, allowing real-time free navigation while minimizing danger missing important structures in visualization. We compare our technique existing local greedy approaches apply it data sets flow visualization, medical imaging, physics, computer graphics.
