There is a plugin on the Marketplace that makes use of this technique, but does it in a very limited way. It started as a c++ code plugging but starting from version 1. Another useful concept is the signed distance field (SDF) which is the subtraction of the inverted EDT from the original EDT. We can compute the signed distance of a set of points in Point-Cloud-Utils in the following way: import numpy as np import point_cloud_utils as pcu # 1000 random query points to compute the SDF at query_pts = np. the magnitude of a point in the field represents the distance to the surface boundary two-manifold, so that their distance field is well-defined. ttf 字体文件转换为多通道有符号距离字段，然后输出包装的spritesheets和 AngelCode BMfont的json表示。符号距离场是从纹理表示中再现向量形状的方法，在中通过阀门的特性得到 体素 (Voxel)：3D空间中的一个小立方体单元，用于分割整个3D空间。在SDF中，我们计算每个体素到物体表面的最短距离。 距离场 (Distance Field)：一个场，其中每个点的值表示到物体表面的最短距离。一个距离场可以是有号（Signed）或无号（Unsigned）的。 有符号距离场 欢迎使用已签名的距离字段存储库。它包含的带符号距离字段系列的示例代码。 虽然回购集中在博客上，但它被设计为一个简单的工具包，用于生成和呈现带符号的距离字段。 A simple commandline utility to generate grid-based signed distance field (level set) generator from triangle meshes, using code from Robert Bridson's website.
