3D Point 😁
***
Если точка имеет координаты x, y, z, значит ли это, что она трехмерная?
например:
P = (10, 20, 30)
у нее есть положение в 3D пространстве.
Есть ли у неё длина, ширина, высота и объём ?

*** то же самое, только злее

у точки в 3D есть три координаты.
у 3D объекта есть три размера.
Координаты и размеры — это одно и то же?
