体积现象是标准渲染的一个组成部分,然而,到目前为止,还没有合适的工具来编辑特征属性。要么直接使用模拟结果,要么进行高级修改,例如,噪声影响外观。直观的艺术控制是不可能的。 我们提出了一个解决方案,styphilic单散射体积效应。发射、散射和消光变得易于艺术控制,同时在改变视点时保持平滑和连贯的外观。我们的方法让用户定义一些目标视图进行匹配时,从这个角度观察体积。通过对体绘制方程的分析,我们可以展示如何将这个问题与层析重建联系起来。
Volumetric phenomena are an integral part of standard rendering, yet, no suitable tools to edit characteristic properties are available so far. Either simulation results are used directly, or modifications are high-level, e.g., noise functions to influence appearance. Intuitive artistic control is not possible. We propose a solution to stylize single-scattering volumetric effects. Emission, scattering and extinction become amenable to artistic control while preserving a smooth and coherent appearance when changing the viewpoint. Our approach lets the user define a number of target views to be matched when observing the volume from this perspective. Via an analysis of the volumetric rendering equation, we can show how to link this problem to tomographic reconstruction.
