Animations can be generated ad hoc in a browser with the CSS 3 features animations, transitions, and sprites, or also the JavaScript web animations API, by specifying frames or motions of still images or rendered shapes. This can be resource-intensive, and the animation generally cannot be saved in a portable image file or posted on imageboards.
Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24 or 48-bit images and full alpha transparency not available for GIFs. It also retains backward compatibility with non-animated PNG files.
The background plane is on the left side of the picture. The highest plane is shown on the right side of the picture. There is a narrow middle plane in the middle of the x-axis. Starting with a background plane where icons are spaced at 140 pixels, one can raise a particular icon by shifting it a certain number of pixels to the left.
For identical 8-bit (or lower) image data, PNG files are typically smaller than the equivalent GIFs, due to the more efficient compression techniques used in PNG encoding. [62] Complete support for GIF is complicated chiefly by the complex canvas structure it allows, though this is what enables the compact animation features.
Microsoft GIF Animator is a historical computer software program for Microsoft Windows to create simple animated GIF files based on the GIF89a file format.It was freely downloadable from the Microsoft Download Center but is now only available through MSDN and on third-party download sites.
Two orbs from Orb Swarm at the Maker Faire 2008.. Orb Swarm (also known simply as SWARM) is a kinetic art work consisting of six semi-autonomous spherical robots. [1] It was created in 2007 by a group of engineers and artists including Michael Prados, Jon Foote, Lee Sonko, and many others. [2]
Not only do animated images form part of computer-generated imagery; natural looking landscapes (such as fractal landscapes) are also generated via computer algorithms. A simple way to generate fractal surfaces is to use an extension of the triangular mesh method, relying on the construction of some special case of a de Rham curve , e.g ...
However, most animations were not intended to give a realistic representation and the distortion isn't very obvious in cartoonish pictures. The distortion and the flicker caused by the rotating slits are not seen in most phénakisticope animations now found online (for instance the GIF animation on this page).
