M_Rhino_Geometry_BoundingBox_IsDegenerate - mcneel/rhinocommon-api-docs GitHub Wiki
Determines whether a bounding box is degenerate (flat) in one or more directions.
Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: Rhino 6.0
C#
public int IsDegenerate(
double tolerance
)VB
Public Function IsDegenerate (
tolerance As Double
) As Integer
- tolerance
- Type: System.Double
Distances <= tolerance will be considered to be zero. If tolerance is negative (default), then a scale invarient tolerance is used.
Type: Int32
0 = box is not degenerate 1 = box is a rectangle (degenerate in one direction). 2 = box is a line (degenerate in two directions). 3 = box is a point (degenerate in three directions) 4 = box is not valid.
