1 year ago You cannot call your scene the same as an Manim object. If you copy the code from the example 1:1
class ExampleLine3D(ThreeDScene):
def construct(self):
axes = ThreeDAxes()
line = Line3D(start=np.array([0, 0, 0]), end=np.array([2, 2, 2]))
self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES)
self.add(axes, line) everything will work fine.
The reason is not Manim but Python: when you write class Line3D(ThreeDScene) you create a new object class which overwrites the existing class Line3D. So when you then try line = Line3D(...) Python will try to create an object of your scene-class, rather the now overwritten original class to draw a line.
Description of bug / unexpected behavior
I am trying to learn how to use manim. I am interested in 3D plots, so I started going through the examples in the reference. So I tried the example in the documentation, https://docs.manim.community/en/stable/reference/manim.mobject.three_d.three_dimensions.Line3D.html . It led to an error,
TypeError: Scene.init() got an unexpected keyword argument 'start'
Expected behavior
I expected the given example to run.
How to reproduce the issue
Copy the example into a file and run manim on it.
Code for reproducing the problem
```py from manim import * class Line3D(ThreeDScene): def construct(self): axes = ThreeDAxes() line = Line3D(start=np.array([0, 0, 0]), end=np.array([2, 2, 2])) self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES) self.add(axes, line) ```Additional media files

This is a new, clean install. The only non-standard thing I did is install manim running pip in sudo.
