Transparency (graphic) 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 fully transparent, or there would be nothing to see.
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.
Pre-DirectX 9 video cards only supported paletted or integer color types. Sometimes another alpha value is added, to be used for transparency. Common formats are: 8 bits per pixel – Sometimes palette mode, where each value is an index in a table with the real color value specified in one of the other formats.
The A-buffer is a computer graphics technique introduced in 1984 which stores per-pixel lists of fragment data (including micro-polygon information) in a software rasteriser, REYES, originally designed for anti-aliasing but also supporting transparency. More recently, depth peeling [1] in 2001 described a hardware accelerated OIT technique ...
GeForce is a brand of graphics processing units (GPUs) designed by Nvidia and marketed for the performance market. As of the GeForce 40 series, there have been eighteen iterations of the design. The first GeForce products were discrete GPUs designed for add-on graphics boards, intended for the high-margin PC gaming market, and later ...

Z-buffering is a technique used in almost all contemporary computers, laptops, and mobile phones for performing 3D computer graphics. The primary use now is for video games, which require fast and accurate processing of 3D scenes. Z-buffers are often implemented in hardware within consumer graphics cards. Z-buffering is also used (implemented ...
As evidenced by the Epstein disclosures, partial transparency comes with inherent dangers and is a threat to the strongest arguments inherent to the case for disclosure. It reveals all too well ...
