It's like manim (the program Grant uses for his channel 3blue1brown) but for computer science! special thanks to Grant Sanderson (3blue1brown, https://github.com/3b1b/manim)

Csanim generates videos. Many test videos can be found on our youtube channel thekeychain

To install csanim, clone this repository, and run the install.sh script. (commands below) This script is only tested for Ubuntu. To install csanim on other systems install the following packages:

• ffmpeg
• python3
• pyhon3-pip
• python3-opengl (or use pip3 install pyopengl)
• dvipng
• texlive
• texlive-latex-extra

installation commands: (Ubuntu):

git clone https://github.com/jonay2000/csanim
cd csanim
./install.sh

To start, import csanim with

from csanim import *

After this import, you can start a new video by creating a frame manager:

#FrameManager(fps,width,height,name)
f = FrameManager(60,1920,1080,"video.mp4") #1080p 60fps
f.set_background(Color(0, 0, 0))

Now you can start defining points in the video at which some change to the seen will happen. This can be done with the @f.second() or @f.frame() decorator.

f.second(sec) will take 1 argument defining on which second the function must be called (this can be a float) f.frame(frame) will take 1 argument defining on which frame the function must be called (this must be an integer)

example:

@f.second(1)	
def second1(manager):

	manager.draw(LatexText(120, #visible for 120 frames (2 seconds on 60fps)
		Color(255,255,255),		#color: white
		100,100,#x,y 			#draw on (100,100)
		1.5,#scale				#scale up by 50%
		r'\int_0^1 e^x\,dx' 	#latex string (integral from 0 to 1 of e^x dx)
		))

now you can start rendering this video by calling the run() method of thye framemanager:

f.run(2*60) #run takes 1 argument specifying how many frames should be rendered. Since the video is on 60 fps
#it should run 120 frames for 2 seconds. After the first second the Latex text will be visible

this last action may take some time, depending on the complexity of the scene. There are currently NO optimizations so slow might mean very slow
