RepairGeometry
enforce clustering of geometry nodes upon read-in (UCV)
RepairGeometry = ( triggerOnNodeDistance, useLocalH, triggerByNormals, applyOnDuplicatedGeometry )
RepairGeometry = ( 0.001, 0, 0.5, 1 )
Default: RepairGeometry = (-1.0, 1, 0.7, 1 )
- triggerOnNodeDistance :: Node points are clustered, if their distance is less than triggerOnNodeDistance * referenceLength
- useLocalH :: if 1 then the referenceLength is the given SMOOTH_LENGTH if 0 then the reference length is the longest edge of the adjacent triangles in the geometry
- triggerByNormals :: cluster two node points only, if the scalar product of the normals is bigger than the given value
- applyOnDuplicatedGeometry :: if 1 then duplicated geometry ( see duplicate{ ) will also repaired, otherwise, it is omitted from the repair procedure
If the triangulation and the corresponding node points of two surfaces sharing a common edge do not conform, unphysical effects may occur at the edge in case of points slipping from one surface to the other or tearing off at the edge. RepairGeometry > 0 enforces clustering of the geometry node points relative to the defined smoothing length upon read-in.
Note:-
The use of this parameter alters the geometry, use with caution and consider remeshing the geometry with respect to conformity of the node points.

RepairGeometry is ignored, if CONTROL_StopAfterReadingGeometry > 0.
