Syntax

public MatOfPoint3f(
	MatOfPoint3f m,
	Rect roi
)

Public Sub New ( 
	m As MatOfPoint3f,
	roi As Rect
)

public:
MatOfPoint3f(
	MatOfPoint3f^ m, 
	Rect roi
)

new : 
        m : MatOfPoint3f * 
        roi : Rect -> MatOfPoint3f

m: Type: OpenCvSharp.CPlusPlusMatOfPoint3f
Array that (as a whole or partly) is assigned to the constructed matrix. No data is copied by these constructors. Instead, the header pointing to m data or its sub-array is constructed and associated with it. The reference counter, if any, is incremented. So, when you modify the matrix formed using such a constructor, you also modify the corresponding elements of m . If you want to have an independent copy of the sub-array, use Mat.Clone() .
roi: Type: OpenCvSharp.CPlusPlusRect
