阴影为渲染图像增添了一定程度的真实感。此外,它们被用作确定空间关系的视觉线索,因此实时阴影将在当前的实时计算机图形应用中变得重要。二十五年前,Crow 发表了用于确定场景阴影区域的阴影体积方法。在本文中,我们提出了一种改进的实时阴影体积算法,可用于增强/混合现实应用程序。最后,所提出的概念为 AR 应用程序提供了一种新颖的视觉输出感。
Shadows add a level of realism to a rendered image. Moreover, they are used as visual clues to determine spacial relationships and real-time shadows will gain importance in current real-time computer graphics applications for this reason. Twenty-five years ago, Crow published the shadow volume approach for determining shadowed regions of a scene. In this paper we present a modified real-time shadow volume algorithm that can be used in an Augmented/Mixed Reality application. Finally, the proposed concepts provide a novel sense of visual output of an AR application.
