Warpalizer is a professional warp and blend software application made by Univisual Technologies AB in Sweden, for use in simulators. [1] [2] [3] [4]Warpalizer can be used for projection on to surfaces that need image geometry correction (warping) to improve the image from the projector, on a cylindrical screen for example.
Edge blending enables the seamless projection of a large image using several overlapping projectors. Since Keystone Distortion (and frequently the requirement of projection onto a non-flat surface) is a built-in requirement of almost all Edge Blending systems, the pairing of Edge blending and image geometry correction in the same video signal ...
DLP and LCD projector edge blend setups show a visible gray seam in the middle in dark scenes. Because of their 4:3 picture tubes, edge-blended CRTs use a larger surface area of the tubes when showing video in a cinemascope aspect ratio, which reduces uneven wear and yields higher total brightness. CRT projector stacking is also possible.
The vector projection (also known as the vector component or vector resolution) of a vector a on (or onto) a nonzero vector b is the orthogonal projection of a onto a straight line parallel to b. The projection of a onto b is often written as proj b a {\displaystyle \operatorname {proj} _{\mathbf {b} }\mathbf {a} } or a ∥ b .
The area is defined to encompass the edge of the target image. As shown in the right hand figure, an operator defines a box area encompassing the edge of a knife-edge test target image back-illuminated by a black body. The box area is defined to be approximately 10% [citation needed] of the total frame area.
Blend modes (alternatively blending modes [1] or mixing modes [2]) in digital image editing and computer graphics are used to determine how two layers are blended ...
Two images stitched together. The photo on the right is distorted slightly so that it matches up with the one on the left. Image stitching or photo stitching is the process of combining multiple photographic images with overlapping fields of view to produce a segmented panorama or high-resolution image.
Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces." [1] Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games.
