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 ...
This can be done in real time by inserting the softwarp as a last step in the rendering cycle. The problem is to know how the image should be warped to look correct on the curved screen. There are several techniques to auto calibrate the warping by projecting a pattern and using cameras and/or sensors.
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.

[1] Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games. Shadows are created by testing whether a pixel is visible from the light source, by comparing the pixel to a z-buffer [ 2 ] or depth image of the light source's view, stored in the form of a texture .
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 ...
