ShowCreation not working for 3d Mobjects

Bug

ShowCreation Animation is not working for three-dimensional mobjects.

Code:

class CubeCreation(Scene):
    def construct(self):
        cube = Cube()
        self.add(cube)
        self.play(ShowCreation(cube))
        self.wait()

class SphereCreation(Scene):
    def construct(self):
        sphere = Sphere()
        self.add(sphere)
        self.play(ShowCreation(sphere))
        self.wait()

Error traceback: For Cube Creation, I am getting this:

“…manim\manimlib\animation\creation.py”, line 30, in interpolate_submobject  start_submob, *self.get_bounds(alpha)

“…manim\manimlib\mobject\types\surface.py”, line 113, in pointwise_become_partial  for arr in smobject.get_surface_points_and_nudged_points()

IndexError: index 0 is out of bounds for axis 1 with size 0

For SphereCreation,

The video is rendered but there is no sphere in the video, it’s just blank background.

Thanks for pointing this out, I believe it is now fixed. Feel free to reopen if other issues arise.
