ZOrder not working properly for NumberPlane in 3D scenes #2447

Open JulioLP opened 2 years ago

JulioLP commented 2 years ago

Description of bug / unexpected behavior

When plotting a sphere and a grid (NumberPlane) in a 3D scene, the NumberPlane is always rendered on top of the sphere (even when the sphere is over it). This does not happen with a ThreeDAxes object and a sphere, for example. Also setting the z_index has no effect.

(edit) Same wrong behavior when using Axes instead of ThreeDAxes. I understand that may happen due to mixing 2D and 3D Mobjects in the same scene, but I believe there are many good reasons to do this in animations (i.e.: using NumberPlane leads to much prettier results than using Surface to plot a simple 2D grid in 3D).

Expected behavior

The last added object should be rendered on top.

How to reproduce the issue

Code for reproducing the problem ```py from manim import * config.media_width = "80%" ``` ```py %%manim -qm -v WARNING ExampleNumberPlaneError class ExampleNumberPlaneError(ThreeDScene): def construct(self): axes = NumberPlane() grid = Surface( lambda u, v: np.array([u,v,0]), u_range=[-4, 4], v_range=[-4, 4], resolution=8, fill_opacity=0.0 ) self.set_camera_orientation(phi=PI / 9, theta=PI / 6) sphere = Sphere(center=(0, 3, 3), radius=1.3) sphere.set_fill(ORANGE) self.add(axes,sphere) ```

This does appear to be an issue, as I tried the argument shade_in_3d=True which usually works to convert 2D MObjects to 3D MObjects - still getting the same issue. I know not adding a whole lot here, but wanted to let you know that someone has looked at this and ended up with the same result.
