SignedDistanceTo(GeoSolid3, GeoPoint3)
Calculates the distance from a solid to a point, negative for a point inside the body.
public static double SignedDistanceTo(GeoSolid3 solid, GeoPoint3 point)Parameters
Returns
SignedDistanceTo(GeoSolid3, GeoPoint3, Tolerance)
Calculates the distance from a solid to a point, negative for a point inside the body, within a tolerance.
public static double SignedDistanceTo(GeoSolid3 solid, GeoPoint3 point, Tolerance tolerance)Parameters
Returns
- double
The distance out to the surface, negative when the point lies in the material.
Remarks
The surface of a pierced body is its faces and the walls of every opening in it, openings of openings included, because that is what Locate(GeoSolid3, GeoPoint3) calls the boundary. So a point in the material beside a duct is measured to the wall of the duct rather than out to the far skin of the body.
SignedDistanceTo(GeoObb3, GeoPoint3)
Calculates the distance from an oriented box to a point, negative for a point inside it.
public static double SignedDistanceTo(GeoObb3 box, GeoPoint3 point)Parameters
Returns
SignedDistanceTo(GeoObb3, GeoPoint3, Tolerance)
Calculates the distance from an oriented box to a point, negative for a point inside it, within a tolerance.
public static double SignedDistanceTo(GeoObb3 box, GeoPoint3 point, Tolerance tolerance)Parameters
Returns
- double
The distance out to the nearest face, negative when the point lies within the box.
Remarks
GetClosestPointOnBoundary(GeoPoint3) clamps a point into the box and so hands an interior point straight back; the magnitude here comes from ProjectToObbSurface(GeoObb3, GeoPoint3), which pushes it out to a face.
SignedDistanceTo(GeoAabb3, GeoPoint3)
Calculates the distance from an axis-aligned box to a point, negative for a point inside it.
public static double SignedDistanceTo(GeoAabb3 box, GeoPoint3 point)Parameters
Returns
SignedDistanceTo(GeoAabb3, GeoPoint3, Tolerance)
Calculates the distance from an axis-aligned box to a point, negative for a point inside it, within a tolerance.
public static double SignedDistanceTo(GeoAabb3 box, GeoPoint3 point, Tolerance tolerance)Parameters
Returns
- double
The distance out to the nearest face, negative when the point lies within the box.
Exceptions
- InvalidOperationException
Thrown when the box is empty, since it has no surface to measure to.
