Facet
surface node
Controls the smoothness of faceting of a surface.
This node also lets you consolidate points or surface normals.
Facet, like Divide, works as a pipeline to change geometry in stages. For this reason, Compute Normals appears twice. For example, you can compute surface normals before making vertices (the points of each polygon) unique, which gives you the unusual result of smooth shading and unique point, as the normals get computed while the points are still shared.
This tool is useful for cleaning up polygons. You can reorient back-facing polygons, remove degenerative polygons, consolidate or unique points, or cusp polygon based on edges.
This op is great for cleaning up geometry read in from .dxf files. It corrects flipped normals present in some .dxf files.
Using Facet
-
Select the faces, edges, or points you want to facet.
-
Click the
Facet tool on the Polygon tab.You can change the facet specifications in the parameter editor.
Parameters

|
Unique Points |
Makes each vertex a unique point. |

Note
The slow versions of consolidation should not be used. They are for backwards compatibility only. |

Distance |
Threshold distance for consolidation. |

|
Distance |
Threshold distance for collinearity. |
