Manim VMobject

VMobject is a Vectorized Mobject. Vector graphics techniques are used to generate 2D graphics and 3D rendering in addition to a ordinary Mobject. A VMobject object is the key element used in Manim as a dummy vmobject container with base vmobject manipulating functions. A VMobject object focuses only on the internal structural design of a VMobject object.
