Remove Non Manifold

拆卸非歧管

The term Non Manifold refers to geometry that doesn’t exist in reality. Technically, this is often edges that are part of more than two polygons. In such cases, geometry is generated but a surface cannot be created for numerous calculations. This affects Phong shading, for example, but also subdivision via Subdivision Surface algorithms.

非流形这个术语指的是在现实中不存在的几何学。从技术上讲，这通常是两个以上多边形的一部分。在这种情况下，生成了几何图形，但无法生成用于大量计算的曲面。例如，这会影响 Phong 着色，但也会通过细分曲面算法进行细分。

This Node’s function makes sure that congruent new points are generated in these regions from which independent polygons can be created that don’t have to share edges multiple times. All polygons that share the same edge will no longer be connected to neighboring polygons.

这个 Node 函数确保在这些区域生成全等的新点，从这些区域可以创建独立的多边形，而不必共享多个边。所有共享相同边缘的多边形将不再连接到相邻的多边形。

By extruding the center edge of the plane, an invalid structure is generated at this location. At this lcoation, an edge is a component of three polygons. This problem is solved automatically via the Remove Non-Manifold Node. 通过挤压平面的中心边缘，在此位置会生成一个无效的结构。在这个坐标系中，边是三个多边形的组成部分。该问题通过移除非流形节点自动解决 >
