Animation | A base class for Animations. |
FuncAnimation | Makes an animation by repeatedly calling a function func. |
ArtistAnimation | Animation using a fixed set of Artist objects. |
In both cases it is critical to keep a reference to the instanceobject. The animation is advanced by a timer (typically from the hostGUI framework) which the Animation object holds the only referenceto. If you do not hold a reference to the Animation object, it (andhence the timers), will be garbage collected which will stop theanimation.
To save an animation to disk use Animation.save or Animation.to_html5_video
Izzy, leader of an underground band or trained assassin? Izzy is created with Character Creator 2.0, a robust 3D character design tool that takes the complexity out of generating fully-rigged custom characters. Characters can exchange outfits, morph to custom face and body shapes, generate emotive facial expressions and lip-sync with any audio. Character Creator works seamlessly with other 3D. Pencil2D is a simple and intuitive tool that helps you create 2D hand-drawn animations. Open-source, and entirely free of cost, it is open to use by anyone, even for commercial purposes. On top of that, it is decidedly user-friendly, making it a perfect tool even for beginners.

FuncAnimation¶
The inner workings of FuncAnimation is more-or-less:
with details to handle 'blitting' (to dramatically improve the liveperformance), to be non-blocking, not repeatedly start/stop the GUIevent loop, handle repeats, multiple animated axes, and easily savethe animation to a movie file.
'Blitting' is a standard technique in computer graphics. Thegeneral gist is to take an existing bit map (in our case a mostlyrasterized figure) and then 'blit' one more artist on top. Thus, bymanaging a saved 'clean' bitmap, we can only re-draw the few artiststhat are changing at each frame and possibly save significant amounts oftime. When we use blitting (by passing blit=True), the core loop ofFuncAnimation gets a bit more complicated:
This is of course leaving out many details (such as updating thebackground when the figure is resized or fully re-drawn). However,this hopefully minimalist example gives a sense of how init_funcand func are used inside of FuncAnimation and the theory of how'blitting' works.
The expected signature on func and init_func is very simple tokeep FuncAnimation out of your book keeping and plotting logic, butthis means that the callable objects you pass in must know whatartists they should be working on. There are several approaches tohandling this, of varying complexity and encapsulation. The simplestapproach, which works quite well in the case of a script, is to define theartist at a global scope and let Python sort things out. For example
The second method is to use functools.partial to 'bind' artists tofunction. A third method is to use closures to build up the requiredartists and functions. A fourth method is to create a class.
