GIF animation of an Apollonian sphere packing with transparent background. Transparency in computer graphics is possible in a number of file formats. The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible. Only part of a graphic should be ...
The illusion derives from the lack of visual cues for depth. For instance, as the dancer's arms move from viewer's left to right, it is possible to view her arms passing between her body and the viewer (that is, in the foreground of the picture, in which case she would be circling counterclockwise on her right foot) and it is also possible to view her arms as passing behind the dancer's body ...
The "Dancing Baby", also called "Baby Cha-Cha" or "the Oogachacka Baby", is an internet meme of a 3D-rendered animation of a baby performing a cha-cha type dance. It quickly became a media phenomenon in the United States and one of the first viral videos in the mid-late 1990s.
After the anime was aired from 17 July to 2 October 2003, short GIF animations clips were created from the opening of the game and posted on the internet. The clips were matched with various songs, with titles ranging from "Popotan dance" to "Sexy bunny dance". [1] In late 2005, a sped-up version of the song was posted by a DJ named Speedycake ...
Extension blocks that modify an image (like the Graphic Control Extension that specifies the optional animation delay time and optional transparent background color) must immediately precede the segment with the image they refer to. Each sub-block begins with a byte giving the number of subsequent data bytes in the sub-block (1 to 255).
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.
Computer animation is essentially a digital successor to stop motion techniques, but using 3D models, and traditional animation techniques using frame-by-frame animation of 2D illustrations. For 2D figure animations, separate objects (illustrations) and separate transparent layers are used with or without that virtual skeleton.
When converting an image from the PNG format to GIF, the image quality may suffer due to posterization if the PNG image has more than 256 colors. GIF intrinsically supports animated images. PNG supports animation only via unofficial extensions (see the section on animation, above). PNG images are less widely supported by older browsers.
