This set of programs for creating animations includes a variety of tools. Here you can find programs for creating GIF animations, Flash movies for web pages, and complex computer animation.
Almost all the programs for creating simple animated pictures and banners work by the principle of composing several pictures, smoothly passing one into another. The transition from one image to another can be created automatically, so you do not need to pre-prepare the slides. In the program, as a rule, you can import images of various formats: JPG, PNG, BMP, etc. Many automation functions will do some work for you - you do not need to have professional skills to create beautiful animations.
As for complex animations, as in computer games, for these purposes you can use the free Blender program, which allows you to create complex moving objects. With a large set of tools and functions, you can create dynamic elements that interact with each other. Examples of such complex objects can be computer characters, pouring water, or a flag developing in the wind.
