Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]).
The simplest application of image geometry correction is a specific case known as keystone distortion correction derived from Keystone effect.Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off ...
A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
Consider an idealised Gaussian optical system, with the image and the object in the same medium.Thus, for an object in focus, the distance between the lens and image plane , the distance between lens and the object , and the focal length are related by the thin-lens equation:
Morphing is a special effect in motion pictures and animations that changes (or morphs) one image or shape into another through a seamless transition. Traditionally such a depiction would be achieved through dissolving techniques on film. Since the early 1990s, this has been replaced by computer software to create more realistic transitions.
Accepts Photoshop plug-ins, to control scanners or apply filters to images. Place drawn objects within text blocks so they flow with the text. Export pages or objects as bitmap images. FreeHand 6.0: Macromedia: only existed in beta: FreeHand 7.0 (update: 7.0.2) Macromedia: 1996: Mac OS, Windows: Drag and drop between both FreeHand and Photoshop.
Projective texture mapping is a method of texture mapping that allows a textured image to be projected onto a scene as if by a slide projector.Projective texture mapping is useful in a variety of lighting techniques and it is the starting point for shadow mapping.
