在三维空间中渲染大量密集线束是许多可视化技术（包括流线和纤维束成像）的常见需求。不幸的是，描述这些线束内部的空间关系通常很困难，但对于理解所表示的结构至关重要。许多方法通过提供特殊的照明模型或管状渲染来解决这个问题。尽管这些方法改善了单条线或相关线组的空间感知，但它们并没有解决密集线束之间复杂空间关系的问题。在本文中，我们提出了一种新颖的方法，通过提供一种适合实时线条渲染的新颖的环境光遮挡方法来改善线条渲染的空间和结构感知。
Rendering large numbers of dense line bundles in three dimensions is a common need for many visualization techniques, including streamlines and fiber tractography. Unfortunately, depiction of spatial relations inside these line bundles is often difficult but critical for understanding the represented structures. Many approaches evolved for solving this problem by providing special illumination models or tube-like renderings. Although these methods improve spatial perception of individual lines or related sets of lines, they do not solve the problem for complex spatial relations between dense bundles of lines. In this paper, we present a novel approach that improves spatial and structural perception of line renderings by providing a novel ambient occlusion approach suited for line rendering in real time.
