从具有 x、y 和 z 坐标的点生成网格 [英] Mesh generation from points with x, y and z coordinates
问题描述
问题:从 3D 点(具有 x、y 和 z 坐标)生成网格.
Problem: Mesh generation from 3D points (with x, y and z coordinates).
我拥有的是 3D 空间中的点(具有 x、y 和 z 坐标)，您可以在图像 1 中看到它.
输出是图像 2 或图像 3，或图像 4.简而言之，它将是网格.如果我有网格，可以提供上面的材料.
What I have is points in 3D space (with x, y and z coordinates) you can see it in image 1.
What would be the output is image 2 or image 3, or image 4. In short it would be mesh. Material on it can be provided if I have the mesh.
我看到很多人说 Delaunay 三角剖分或约束 Delaunay 三角剖分将帮助我生成网格，但我主要发现的是它在 2D 点(只有 x 和 Y 坐标)中的实现.
I have seen many people say about Delaunay triangulations or constrained Delaunay triangulations will help me in mesh generation, but what I mostly found is its implementation in 2D points (with only x and Y coordinates).
但我的问题是:从图 1 中可以看出，我有 3D 点.
But my problem is: I have points in 3D as you can see from image 1.
Delaunay 三角剖分或约束 Delaunay 三角剖分是否适用于 3D 点?如果是，那么如何?还是我必须找到另一种算法来从 3D 点生成网格?
Will Delaunay triangulations or constrained Delaunay triangulations work fine with 3D Points? If yes, then how? Or do I have to find another algorithm for generating mesh from 3D points?
