Tool for live presentations using manim
pip install manim-presentation opencv-python
Use the class Slide as your scenes base class
from manim_presentation import Slide
class Example(Slide):
def construct(self):
...call self.pause() when you want to pause the playback and wait for an input to continue (check the keybindings)
Wrap a series of animations between self.start_loop() and self.stop_loop() when you want to loop them (until input to continue)
from manim import *
from manim_presentation import Slide
class Example(Slide):
def construct(self):
circle = Circle(radius=3, color=BLUE)
dot = Dot()
self.play(GrowFromCenter(circle))
self.pause()
self.start_loop()
self.play(MoveAlongPath(dot, circle), run_time=2, rate_func=linear)
self.end_loop()
self.play(dot.animate.move_to(ORIGIN))
self.pause()
self.wait()You must end your Slide with a self.play(...) or a self.wait(..)
To start the presentation using Scene1, Scene2 and so on simply run:
manim_presentation Scene1 Scene2...
Default keybindings to control the presentation
| Keybinding | Action |
|---|---|
| Right Arrow | Continue/Next Slide |
| Left Arrow | Previous Slide |
| R | Re-Animate Current Slide |
| Spacebar | Play/Pause |
| Q | Quit |
You can run the configuration wizard with
manim-presentation-wizard
Alternatively you can specify different keybindings creating a file named manim-presentation.json with the keys: QUIT_KEY CONTINUE_KEY BACK_KEY REWIND_KEY and PLAYPAUSE_KEY
manim-presentation uses cv2.waitKeyEx() to wait for keypresses
