Anima is a JS plugin that can animate many objects at the same time. And each object has its own mass and density to mimic real-life objects.CSS3 animations have some limitations, and the main thing is that you can't really control them completely. If you don't use a few tricks, you'll almost never stop the animation transition.Anima is a basic physics-based JS
Animation is the best companion of Childhood, such as "Gourd Doll", "Journey to the Monkey" and other fixed animation are accompanied by our growth, left in the memory of childhood. Now to create a childhood animation, has not been anything difficult, I can also action made. So what software is good for stop-motion

Transform Linux into a real-time operating system-general Linux technology-Linux programming and kernel information. The following is a detailed description. In the past, many embedded systems were not an operating system, a provider's proprietary core, or a DOS Operating System Extension. Obviously, these methods cannot meet the requirements of embedded system development today! Although some existing comm

Better performance: Vg.net's animation algorithm ensures that each redraw will draw only the smallest, changing parts and supports hardware acceleration. objects in a vector graph use
child elements "inherit" the appearance unless they have the same properties.
Style object: Attach a Style object to a picture, modify the appearance, name of any style object defined on the picture, and, by referencing the appearance of a child element, each Style object contains a fill, stroke, text appearance, and appearance rendering properties.

In general, making an animation does not select a pixel layer because its action attributes are too small to be manipulated, as we do when designing the UI without directly drawing in pixels. If we need to make an
