Brep.IsPointInside Method

BrepIsPointInside Method

Determines if point is inside a Brep. This question only makes sense when the brep is a closed and manifold. This function does not check for closed or manifold, so result is not valid in those cases. Intersects a line through point with brep, finds the intersection point Q closest to point, and looks at face normal at Q. If the point Q is on an edge or the intersection is not transverse at Q, then another line is used.

Syntax
Copy
public bool IsPointInside(
	Point3d point,
	double tolerance,
	bool strictlyIn
)
Public Function IsPointInside ( 
	point As Point3d,
	tolerance As Double,
	strictlyIn As Boolean
) As Boolean

Parameters

point
Type: Rhino.GeometryPoint3d
3d point to test.
tolerance
Type: SystemDouble
3d distance tolerance used for intersection and determining strict inclusion. A good default is RhinoMath.SqrtEpsilon.
strictlyIn
Type: SystemBoolean
if true, point is in if inside brep by at least tolerance. if false, point is in if truly in or within tolerance of boundary.

Return Value

Type: Boolean
true if point is in, false if not.
