changelog

OpenGLMobject

⚠️ Might be inconsistent with current state of the PR ⚠️

Additions:
init_constructor, __add__, __mul__, are_points_touching, is_touching, apply_over_attr_arrays, get_ancestors, insert_submobject, set_submobject, set_rgba_array, set_color_by_rgba_func, set_color_by_rgb_func, set_rgba_array_by_color, arrange_to_fit_dim, replicate
Renamed:
set_rgba_array -> set_rgba_array_by_color (added new set_rgba_array)
set_rgba_array_direct -> set_rgba_array

Removed/Depcrecated:
set_rgba_array_direct

Changes:

  • self.uniform.fixed_orientation_center is now a np.ndarray
  • __init__:
    • Now holds all initial self.x = x assignments and the rest of the constructor which is useful to see is now in init_constructor
  • set_points:
    • Uses asarray instead of array to not unnecessarily copy arrays when not needed.
  • add_updater:
    • now uses self.update(dt=0)
  • set_color:
    • now uses set_rgba_array_by_color instead of setting color directly
  • set_opacity:
    • now uses set_rgba_array_by_color
  • interpolate:
    • now treats all uniforms equally
  • fix_orientation:
    • creates a np.ndarray to set fixed_orientation_center instead of tuple

Temporary changes:

  • check_data_alignment:
    • Does not directly work on self.data instead returns the new result directly to be used in get_resized_shader_data_array

OpenGLVmobject

Additions:

  • @property:stroke_opacity, _stroke_opacity, @property:stroke_width, _stroke_width

Removed/Deprecated

Changes:

Temporary changes:


Shader

Additions:

Removed/Deprecated

Changes:

  • set_uniform:
    • now converts np.ndarray to tuple for easier outside usage to only need to convert on the last step when creating uniforms

Temporary changes:


Reviewer Checklist

  • The PR title is descriptive enough for the changelog, and the PR is labeled correctly
  • If applicable: newly added non-private functions and classes have a docstring including a short summary and a PARAMETERS section
  • If applicable: newly added functions and classes are tested

I'll make this a draft for now (and I don't expect the tests to pass any time soon) -- but we'll try some more drastic refactoring strategies here.

A missing point resulted in smaller bounding box causing issues it to be

* feat(cli): optionally hide version splash (#3329)

* feat(cli): optionally hide version splash

As discussed in #3326, this PR proposes a new optional flag to hide the version splash when manim command in launched. Additionally, the splash print is now inly executed when the CLI is executed, not on module import.

After looking at the current documentation, it does not seem to change anything. I only saw that you documented a version splash for when the CLI is used, but not when the module is imported. So removing it should not break the api docs.

In the future, users can still have version information with `import manim; print(manim.__version__)`.

Closes #3326

* Account for dtype in the pixel array so the maximum value stays correct in the invert function (#3493)

* fix(lib): fix

This fixes an issue where the `invert` argument would only work for `uint8` dtypes. Now the `max` value is updated according to the pixel array dtype.

Maybe we should add unit tests for that, but haven't found an obvious place to put unit tests.

* fix: issue with ImageMobject bounding box (#3340)

* fix: fix an issue with ImageMobject bounding box

A missing point resulted in smaller bounding box causing issues it to be
smaller when the object is rotated. Added the missing fourth point to
ImageMobject points and altered call from camera. Filled in docstring
that used to propagate from superclass, saying that ImageMobject has no
points.

* add a test to check that rotating an image to and from doesn't change it

* feat(cli): optionally hide version splash (#3329)

* feat(cli): optionally hide version splash

As discussed in #3326, this PR proposes a new optional flag to hide the version splash when manim command in launched. Additionally, the splash print is now inly executed when the CLI is executed, not on module import.

After looking at the current documentation, it does not seem to change anything. I only saw that you documented a version splash for when the CLI is used, but not when the module is imported. So removing it should not break the api docs.

In the future, users can still have version information with `import manim; print(manim.__version__)`.

Closes #3326

* Account for dtype in the pixel array so the maximum value stays correct in the invert function (#3493)

* fix(lib): fix

This fixes an issue where the `invert` argument would only work for `uint8` dtypes. Now the `max` value is updated according to the pixel array dtype.

Maybe we should add unit tests for that, but haven't found an obvious place to put unit tests.
