在本文中,我们提出了一种半透明绘制技术,它可以完整地处理不规则体和多边形,而不需要对可见性进行排序。用于绘制不规则体积的投影技术需要很大的存储空间来计算每个观察点的可见性分类。为了解决这一问题,我们将亮度方程视为取样点沿观察光线的亮度的期望值,并提出了一种无需排序的方法,该方法通过使用评估的不透明度值来计算渲染图像来简单地控制片段渲染。在我们的实验中,我们将我们的技术应用到了几个数值模拟结果中,并通过绘制带有半透明边界多边形的体并展示了我们的技术在高分辨率分布式显示系统中的应用来验证其有效性。
In this paper, we propose a technique for semitransparent rendering, which can integrally handle irregular volumes and polygons without visibility sorting. A projection technique for rendering of the irregular volumes requires a large memory space to calculate the visibility sorting at each viewing point. To solve the problem, we regard the brightness equation as the expected value of the luminosity of a sampling point along a viewing ray, and we propose a sorting-free approach that simply controls the fragment rendering by using the evaluated opacity value to calculate a rendered image. In our experiments, we applied our technique to several numerical simulation results and confirmed its effectiveness by rendering the volume with its semi-transparent boundary polygons and demonstrating the application of our technique to a high-resolution distributed display system.
