LineAO—Improved Three-Dimensional Line Rendering

Abstract: 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 … Show more

“…Also, another enhancement could be done by using an algorithm that investigates the optimal viewpoints, which can uniquely illustrates the flow field and have minimal average depth layers size (number of linked list elements). Moreover, enhance the quality of the rendered lines by applying some shading techniques as the o;[ne presented by Malloet al [7] or LineAO method by Eichelbaum et al [3]. Also, combine our work with other optimization methods for lines selection, namely, Opacity Optimization method provided by Gnther et al [5].…”

“…Entretanto, eles não conseguem resolver o problema de relações espaciais complexas em conjuntos densos de linhas. Eichelbaum et al [1] propõem um método de oclusão de ambiente que melhora a percepção espacial e estrutural de linhas, combinando iluminação global ambiente com as contribuições das reflexões das linhas na vizinhança, mantendo assim a espessura da linha que é necessária para garantir a consistência sobre interação no modelo.…”

“…LineAO [1] introduz um esquema de amostragem que resolve o problema da baixa resolução espacial em espaço de tela muito comum nas técnicas de SSAO. Através da extensão da Equação 1.3, pode-se amostrar as linhas que estão perto e distante e classificá-las por níveis de distância.…”
