  2. Image geometry correction - Wikipedia

    en.wikipedia.org/wiki/Image_geometry_correction

    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 ...

  3. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    Mapping a two-dimensional texture onto a 3D model 1: 3D model without textures 2: Same model with textures. Texture mapping [1] [2] [3] is a term used in computer graphics to describe how 2D images are projected onto 3D models.

  4. Avid Elastic Reality - Wikipedia

    en.wikipedia.org/wiki/Avid_Elastic_Reality

    Elastic Reality made its name with the ease of use of its tool, and the quality of the resulting warps. Other warping tools have typically offered a simpler warping and morphing based on animating points on a grid, which can require significantly more work from the artist to animate distortion of organic shapes such as human faces.

  5. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    In the 20th century, perspective distortion expanded into photography and modern art, with wide-angle and telephoto lenses creating exaggerated or compressed views. Photographers like André Kertész used distortion to evoke emotional or psychological responses, while surrealists like Salvador Dalí distorted perspective to challenge reality ...

  7. Image warping - Wikipedia

    en.wikipedia.org/wiki/Image_warping

    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 same techniques are equally applicable to video.

  8. Morphing - Wikipedia

    en.wikipedia.org/wiki/Morphing

    Long before digital morphing, several techniques were used for similar image transformations. Some of those techniques are closer to a matched dissolve - a gradual change between two pictures without warping the shapes in the images - while others did change the shapes in between the start and end phases of the transformation.

  9. Asynchronous reprojection - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_reprojection

    Reprojection involves the headset's driver taking one or multiple previously rendered frames and using newer motion information from the headset's sensors to extrapolate (often referred to as "reprojecting" or "warping") the previous frame into a prediction of what a normally rendered frame would look like. [2] "Asynchronous" refers to this ...
