摘要

我们提出了一种包含尖锐细节的隐实体体素化的新方法。如果用普通技术处理这些对象,可能会出现体素化伪影,导致渲染图像出现锯齿状边缘。为了解决这个问题,我们提出了一种叫做“锐利细节校正”的技术。其主要思想是在体素化过程中根据可表征性准则对目标进行修改。这意味着尖锐的边缘和顶点被圆润成曲率,这取决于网格分辨率。因此,我们获得无伪像的体素化固体,产生无别名的图像。

Representation of objects with sharp details in truncated distance fields
We present a new approach for voxelization of implicit solids which contain sharp details. If such objects are processed by common techniques, voxelization artifacts may appear, resulting, among others, in jaggy edges in rendered images. To cope with this problem we proposed a technique called sharp details correction. The main idea is to modify objects during the process of voxelization according to the representability criterion. This means that sharp edges end vertices are rounded to a curvature, which depends on the grid resolution. Thus, we obtain artifact-free voxelized solids which produce alias-free images.
