Vector3iVector
¶ Convert int32 numpy array of shape
(n, 3)
to Open3D format..Example usage

-
append
(self: open3d.utility.Vector3iVector, x: numpy.ndarray[int32[3, 1]]) → None¶ Add an item to the end of the list
-
count
(self: open3d.utility.Vector3iVector, x: numpy.ndarray[int32[3, 1]]) → int¶ Return the number of times
x
appears in the list
-
extend
(*args, **kwargs)¶ Overloaded function.
extend(self: open3d.utility.Vector3iVector, L: open3d.utility.Vector3iVector) -> None
Extend the list by appending all the items in the given list
extend(self: open3d.utility.Vector3iVector, L: iterable) -> None
Extend the list by appending all the items in the given list
-
insert
(self: open3d.utility.Vector3iVector, i: int, x: numpy.ndarray[int32[3, 1]]) → None¶ Insert an item at a given position.
-
pop
(*args, **kwargs)¶ Overloaded function.
pop(self: open3d.utility.Vector3iVector) -> numpy.ndarray[int32[3, 1]]
Remove and return the last item
pop(self: open3d.utility.Vector3iVector, i: int) -> numpy.ndarray[int32[3, 1]]
Remove and return the item at index
i
-
remove
(self: open3d.utility.Vector3iVector, x: numpy.ndarray[int32[3, 1]]) → None¶ Remove the first item from the list whose value is x. It is an error if there is no such item.
