Holographic print

A holographic print is a type of print that contains a three-dimensional image. This image is created by using a laser to record an interference pattern on a photosensitive surface. When the print is viewed, the interference pattern is reconstructed, creating the illusion of a three-dimensional image. How do you make Holo prints? To make … Read more

AC-3 (Dolby Digital)

AC-3 (Dolby Digital) is a lossy audio compression algorithm used in many digital audio applications, such as DVD, Blu-ray, and HDTV. It is based on the perceptual model of auditory masking, which predicts the minimum audible threshold for a given signal in the presence of background noise. AC-3 was developed by Dolby Laboratories in 1987 … Read more

Vector graphics

Vector graphics are computer graphics images that are defined in terms of 2D points, which are connected by lines and curves to form polygons and other shapes. Each of these points has a definite position on the x- and y-axis of the work plane and determines the direction of the path; further, each path may … Read more


Z-buffering is a method used in computer graphics to determine which areas of a three-dimensional (3D) image should be visible. Z-buffering works by assigning each pixel in an image a Z-value, which corresponds to the distance of that pixel from the viewer. Pixels with a higher Z-value are closer to the viewer, and therefore should … Read more


A vocoder is a type of audio codec that compresses and decompresses digital audio data. The term is short for “voice coder.” Vocoders are used in a variety of applications, including voice over IP (VoIP), voice recognition, speech synthesis, and audio compression. Is a vocoder like Autotune? A vocoder is a device that is used … Read more

Video wall

A video wall is a large display consisting of multiple smaller monitors or screens that are arranged together to form one large display. Video walls are often used in public places such as airports, shopping malls, and other high-traffic areas where they can be used to display information such as flight times, weather reports, or … Read more

3D gaming

3D gaming involves the use of three-dimensional graphics and environments to create a realistic gaming experience. This type of gaming can be achieved by using special hardware, such as a 3D graphics card, or by using special software that can render 3D images. 3D gaming can also be achieved by using a head-mounted display, which … Read more
