ImageMobject in ThreeDScene Camera Move Issue

Open helblazer811 opened this issue 3 years ago • 1 comments

Description of bug / unexpected behavior

When I do a move animation on the the frame_center in a ThreeDScene, an ImageMobject is shifted a different amount from the rest of the mobjects in the scene.

Expected behavior

Both the Square and the ImageMobject should move the same amount.

How to reproduce the issue

from manim import *

from PIL import Image
import numpy as np

class NeuralNetworkScene(ThreeDScene):
    """Test Scene for the Neural Network"""

    def construct(self):
        # Make the Layer object
        image = Image.open("../assets/mnist/digit.jpeg")
        numpy_image = np.asarray(image)

        square = Square().shift([0.0, 2.5, 0.0])
        self.add(square)

        image_mobject = ImageMobject(
            numpy_image, 
            image_mode="RGB"
        ).scale(10)

        self.add(image_mobject)
        self.play(
            self.camera._frame_center.animate.shift(
                np.array([3.0, 0.0, 0])
            )
        )
