Manim Constants¶
The constants.py
under manimlib/
contains variables that are used
during setup and running manim. Some variables are not documented here as they are
only used internally by manim.
Directories¶
- MEDIA_DIR
- The directory where
VIDEO_DIR
andTEX_DIR
will be created, if they aren’t specified via flags.- VIDEO_DIR
- Used to store the scenes rendered by Manim. When a scene is finished rendering, it will be stored under
VIDEO_DIR/module_name/scene_name/quality/scene_name.mp4
. Created underMEDIA_DIR
by default.- TEX_DIR
- Files written by Latex are stored here. It also acts as a cache so that the files aren’t rewritten each time Latex is needed.
Those directories are created if they don’t exist.
Tex¶
- TEX_USE_CTEX
- A boolean value. Change it to True if you need to use Chinese typesetting.
- TEX_TEXT_TO_REPLACE
- Placeholder text used by manim when generating tex files
- TEMPLATE_TEX_FILE
- By default
manimlib/tex_template.tex
is used. IfTEX_USE_CTEX
is set to True thenmanimlib/ctex_template.tex
is used.
Numerical Constants¶
- PI
- alias to
numpy.pi
- TAU
- PI * 2
- DEGREES
- TAU / 360
Camera Configuration¶
Render setting presets
- PRODUCTION_QUALITY_CAMERA_CONFIG
- 2560x1440 @ 60fps # This is the default when rendering a scene
- HIGH_QUALITY_CAMERA_CONFIG
- 1920x1080 @ 60fps. # Used when the
-h
or--high_quality
flag is passed.- MEDIUM_QUALITY_CAMERA_CONFIG
- 1280x720 @ 30fps. # Used when the
-m
or--medium_quality
flag is passed.- LOW_QUALITY_CAMERA_CONFIG
- 854x480 @ 15fps. # Used when the
-l
or--low_quality
flag is passed.
Coordinates¶
Used for 2d/3d animations and placements:
ORIGIN
UP
DOWN
RIGHT
LEFT
IN # 3d camera only, away from camera
OUT # 3d camera only, close to camera
UL = UP + LEFT # diagonal abbreviations. You can use either one
UR = UP + RIGHT
DL = DOWN + LEFT
DR = DOWN + RIGHT
TOP
BOTTOM
LEFT_SIDE
RIGHT_SIDE``
Colors¶
- COLOR_MAP
- A predefined color maps
- PALETTE
- A list of color hex strings, derived from COLOR_MAP
