Creates a cutting plane through a mesh.
Usage🔗
Basic operation of the distanceSurface
surface comprises:
surfaces1
{
type surfaces;
libs (sampling);
surfaces
{
mySurface1
{
type distanceSurface;
surfaceType triSurfaceMesh;
// Optional
surfaceName mySurface.obj;
distance 0;
signed true;
topology <topology-type>;
absProximity 1e-5;
maxDistance 1000;
}
}
}
The topology-type
value can be::
-
none
: no filtering
Pre-filter options:
-
largestRegion
: pre-filter - retains the region with the most cut cells -
nearestPoints
: pre-filter - retains the regions where cut cells are closest to the set user-defined points. Requires additional input:
topology nearestPoints;
nearestPoints
(
(0 0 0)
(1 0 0)
(1 1 0)
);
Post-filter options:
-
proximityRegions
: post filter - uses the area-weighted distance of each topologically connected region to the input surface to reject regions at a distance greater thanabsProximity
-
proximityFaces
: post-filter - rejects resulting faces with a distance greater thanabsProximity
from the input surface -
proximity
: post-filter - same asproximityFaces
