Mesh.IsPointInside

Public Class

Determines if a point is inside a solid mesh.

Namespace: Rhino.Geometry

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**5.0

Syntax

public bool IsPointInside(
  Point3d point,
  double tolerance,
  bool strictlyIn
)

Parameters

point

Type: Rhino.Geometry.Point3d
3d point to test.

tolerance

Type:System.Double
(>=0) 3d distance tolerance used for ray-mesh intersection and determining strict inclusion. This is expected to be a tiny value.

strictlyIn

Type:System.Boolean
If strictlyIn is true, then point must be inside mesh by at least tolerance in order for this function to return true. If strictlyIn is false, then this function will return true if point is inside or the distance from point to a mesh face is <= tolerance.

Return Value

Type:Boolean
true if point is inside the solid mesh, false if not.

Remarks

The caller is responsible for making certain the mesh is valid, closed, and 2-manifold before calling this function. If the mesh is not, the behavior is undetermined.
