In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite .
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.
Pivot Animator (formerly Pivot Stickfigure Animator and usually shortened to Pivot) is a freeware application that allows users to create stick-figure and sprite animations, and save them in the animated GIF format for use on web pages and the AVI format (in Pivot Animator 3 and later).
Blender users can create their own nodes using the Open Shading Language (OSL); this allows users to create stunning materials that are entirely procedural, which allows them to be used on any objects without stretching the texture as opposed to image-based textures which need to be made to fit a certain object. (Note that the shader nodes ...
Pixel art [note 1] is a form of digital art drawn with graphical software where images are built using pixels as the only building block. [2] It is widely associated with the low-resolution graphics from 8-bit and 16-bit era computers, arcade machines and video game consoles, in addition to other limited systems such as LED displays and graphing calculators, which have a limited number of ...
The metafile format is an intermediate format. Most applications open metafiles and then save them in their own native format. Page description language refers to formats used to describe the layout of a printed page containing text, objects and images. Examples are PostScript, PDF and PCL.
A polarized 3D system uses polarization glasses to create the illusion of three-dimensional images by restricting the light that reaches each eye (an example of stereoscopy). To present stereoscopic images and films, two images are projected superimposed onto the same screen or display through different polarizing filters. The viewer wears low ...
N would depend on the video speed (number of images per second in the video) and the amount of movement in the video. [4] After calculating the background B(x,y,t) we can then subtract it from the image V(x,y,t) at time t = t and threshold it. Thus the foreground is:
