Divide
surface node
Divides, smoothes, and triangulates polygons.
See also: Clip, Cookie, Edge Divide, Poly Split
This operator performs two specific tasks:
-
Smooth by subdividing.
-
Cleanup polygons: fix concave polygons, divide N-side polygons into triangles or quads with optional brickered layout, triangulate non-planar polygons.
Notes
-
Divide has an optional second input for rest geometry. This input applies only to the convexing functionality. When the second input is connected, the Divide node will use the points from the rest geometry to perform convexing. In order for this to work appropriately, the point indices in the main input geometry must match those in the rest geometry.
Parameters
|
Convex Polygons |
Split all concave polygons to make them convex. |
|
Maximum Edges |
Restrict the number of edges in each polygon to be equal to or less than this number. If a polygon has more edges, it is divided into smaller polygons. |
|
Triangulate Non-Planar |
Triangulates non-planar primitives when turned on. A non-planar primitive is a primitive whose vertices do not all lie on the same plane. The slider represents the tolerance at which to determine whether or not a primitive is non-planar. A planar primitive that is transformed or altered in some other way, could become non-planar due to numerical computation error. A value can be computed to measure how non-planar it is. If this measurement falls below the tolerance level, the primitive is deemed planar and does not get divided. Conversely, if the measurement is above the tolerance level, it is deemed non-planar and is divided. |
|
Smooth Polygons |
Subdivide adjacent non-flat polygons. Smoothed polygons must have shared points. |
|
Weight |
Localizes the effect of polygon smoothing. |
|
Divisions |
Number of levels of subdivision. Each level doubles the number of polygons. |
|
Bricker Polygons |
Divide the polygon into a mesh-like series of polygons. This aids in surface deformation operations. |
|
Size, Offset, Angle |
Control the layout of brickered polygons. |
|
Remove Shared Edges |
Remove common edges. |
|
Compute Dual |
Convert the polyhedron into its point/face dual. |
