* Comment tweak * Directly print traceback Since the shell.showtraceback is giving some issues * Make InteracrtiveSceneEmbed into a class This way it can keep track of it's internal shell; use of get_ipython has a finicky relationship with reloading. * Move remaining checkpoint_paste logic into scene_embed.py This involved making a few context managers for Scene: temp_record, temp_skip, temp_progress_bar, which seem useful in and of themselves. * Change null key to be the empty string * Ensure temporary svg paths for Text are deleted * Remove unused dict_ops.py functions * Remove break_into_partial_movies from file_writer configuration * Rewrite guarantee_existence using Path * Clean up SceneFileWriter It had a number of vestigial functions no longer used, and some setup that could be made more organized. * Remove --save_pngs CLI arg (which did nothing) * Add --subdivide CLI arg * Remove add_extension_if_not_present * Remove get_sorted_integer_files * Have find_file return Path * Minor clean up * Clean up num_tex_symbols * Fix find_file * Minor cleanup for extract_scene.py * Add preview_frame_while_skipping option to scene config * Use shell.showtraceback function * Move keybindings to config, instead of in-place constants * Replace DEGREES -> DEG

constants
|
|
=========
|
|
|
|
The ``constants.py`` in the ``manimlib`` folder defines the constants
|
|
needed when running manim. Some constants are not explained here because
|
|
they are only used inside manim.
|
|
|
|
Frame and pixel shape
|
|
---------------------
|
|
|
|
These values will be determined based on the ``camera`` configuration in default_config.yml or custom_config.yml
|
|
|
|
.. code-block:: python
|
|
|
|
ASPECT_RATIO
|
|
FRAME_HEIGHT
|
|
FRAME_WIDTH
|
|
FRAME_Y_RADIUS
|
|
FRAME_X_RADIUS
|
|
|
|
DEFAULT_PIXEL_HEIGHT
|
|
DEFAULT_PIXEL_WIDTH
|
|
DEFAULT_FPS
|
|
|
|
Buffs
|
|
-----
|
|
|
|
These values will be determined based on the ``size`` configuration in default_config.yml or custom_config.yml
|
|
|
|
|
|
.. code-block:: python
|
|
|
|
SMALL_BUFF
|
|

|
Coordinates
|
|
-----------
|
|
|
|
manim uses three-dimensional coordinates and uses the type of ``ndarray``
|
|
|
|
.. code-block:: python
|
|
|
|
ORIGIN = np.array((0., 0., 0.))
|
|
UP = np.array((0., 1., 0.))
|
|
DOWN = np.array((0., -1., 0.))
|
|
RIGHT = np.array((1., 0., 0.))
|
|
LEFT = np.array((-1., 0., 0.))
|
|
IN = np.array((0., 0., -1.))
|
|
OUT = np.array((0., 0., 1.))
|
|
X_AXIS = np.array((1., 0., 0.))
|
|
Y_AXIS = np.array((0., 1., 0.))
|
|
Z_AXIS = np.array((0., 0., 1.))
|
|
|
|
# Useful abbreviations for diagonals
|
|
UL = UP + LEFT
|
|
UR = UP + RIGHT
|
|
DL = DOWN + LEFT
|
|
DR = DOWN + RIGHT
|
|
|
|
TOP = FRAME_Y_RADIUS * UP
|
|
BOTTOM = FRAME_Y_RADIUS * DOWN
|
|
LEFT_SIDE = FRAME_X_RADIUS * LEFT
|
|
RIGHT_SIDE = FRAME_X_RADIUS * RIGHT
|
|
|
|
Mathematical constant
|
|
---------------------
|
|
|
|
.. code-block:: python
|
|
|
|
PI = np.pi
|
|
TAU = 2 * PI
|
|
DEG = TAU / 360
|
|
|
|
Text
|
|
----
|
|
|
|
.. code-block:: python
|
|
|
|
NORMAL = "NORMAL"
|
|
ITALIC = "ITALIC"
|
|
OBLIQUE = "OBLIQUE"
|
|
BOLD = "BOLD"
|
|
|
|
Colours
|
|
-------
|
|
|
|
Color constants are determined based on the ``color`` configuration in default_config.yml or custom_config.yml
|
|
|
|
Here are the preview of default colours. (Modified from
