complex functions acting strange #498

Open tjf801 opened 5 years ago

tjf801 commented 5 years ago

When I try to run a complex transformation, it runs fine, unless the function has a pole. I would like if someone could tell me what I could do to fix this. Thanks in advance.

Code: Capture

Middle: Capture

Last frame: Capture

Can you show me how you get complex Transformation of the whole coordinate plane for any Function?

tjf801 commented 4 years ago

I'm A little late but you change the lambda function in CONFIG to whatever you want.

Rousan99 commented 4 years ago

But I don't understand why you use self.apply_complex_function(self.function) Why not self.apply_complex_function(zeta)?

Hi, were you able to solve this problem? I'm having the same problem myself right not, wondering if there's some way to fix it. Thank you

tjf801 commented 4 years ago

sadly no. I wish though lol

giladsofer commented 4 years ago

Right now I'm trying to check the [discontinuity fix code](https://github.com/3b1b/manim/pull/832), but I'm having some trouble understanding how to use it.

After several days I managed to solve the problem with the current version of manim

Could you please post the code you used for this specific animation? Just to see how your method is applied in context? Thank you

This works fine for the zeta Transformation of complete plane but it doesn't work for the transformation of half plane. It is showing something like this: IMG_20200716_005955

Check my code #1169

class TestZetaOnHalfPlane(ZetaTransformationScene): CONFIG = { "anchor_density" : 15, } def construct(self): self.add_transformable_plane() prueba = self.get_dense_grid() self.plane.submobjects = [prueba] self.apply_zeta_function() texto = TextMobject("yinjann") texto.scale(0.8) texto.to_corner(DOWN + RIGHT) self.play(Write(texto)) self.wait(3)

Not completely related, but - how were you able to define your function on only half of the plane? I want to make animations of functions acting on the upper half plane
