Parametric Function not intersecting with Dot3D #3710

Closed internot169 closed 6 months ago

internot169 commented 6 months ago

Description of bug / unexpected behavior

We have a parametric function which we know intersects with two points. However, when rendering the two points and the function, the function does not intersect with the points.

Expected behavior

We expect the function to intersect with the points. This isn't a math issue: I have tried the function and points in GeoGebra and it works.

How to reproduce the issue

Code for reproducing the problem ```py class Main(ThreeDScene): def construct(self): axes = ThreeDAxes() curve = ParametricFunction( lambda u: np.array([ 1 + u, 3 * u, 4 - (5 * u) ]), color=RED, t_range = np.array([0, 1, 0.001]) ).set_shade_in_3d(True) self.set_camera_orientation(phi=75 * DEGREES, theta=30 * DEGREES) dot_1 = Dot3D(point=axes.coords_to_point(1, 0, 4), radius=0.1, color=RED) dot_2 = Dot3D(point=axes.coords_to_point(2, 3, -1), radius=0.1, color=BLUE) dot_3 = Dot3D(point=[0, 1, -2], radius=0.1, color=ORANGE) self.add(dot_1, dot_2, dot_3) self.play(Write(axes)) self.play(Create(curve)) self.wait() ```

Sorry, Installed LaTeX packages are MiKTeX

your ParametricFunction() object uses scene coordinates, not the ones defined by your axes object, while you place your dots using the local coordinate system of your axes object.

before: image

after: image

        curve = axes.plot_parametric_curve(
            lambda u: np.array([
                1 + u,
                3 * u,
                4 - (5 * u)
            ]), color=RED, t_range = np.array([0, 1, 0.001])
        ).set_shade_in_3d(True)

Thanks! It works now.
