Normalised screen coordinates range from -aspect to aspect ratio in the horizontal Texture coordinate of that node (range from 0 to 1), and finally a multiplicative intensity These linesĬonsist of x and y (the coordinate of the mesh in normalised screen coordinates), the u and v Subsequent lines contain 5 numbers per line that describe each node of the mesh. The mesh is assumed to apply to, the second line gives the dimensions of the mesh, the Line contains a single digit that indicates the input image format The format is as follows: the file is a plain (human readable) The data file that describes the warping is simply a description of a regular mesh Warped image for spherical mirror projection, 16x9. Warped image for spherical mirror projection, 4x3. Truncated fisheye as used by many fisheye projector systems. For all practical purposesĪny image distortion can be achieved, it only requires that someone can create the correct Turned on in order to illustrate the nature of the texture mapping. Shown in multiple environments without being preprocessed for each. The power of this approach is immediately obvious, namely that one movie can be A sample frame is shown below along with various mappings. The following example is targeted at fisheye movies, the original frame is taken from In the users home directory, then the path to the file would be (noting that it is case sensitive) So, if the warpįile is called 'default.data', if the user account name is 'Domeuser', and the warp file is located Noting that the whole path to the file is required. Until a fix for this is found, it is necessary to set the location of the warp meshįile explicitely in the preferences. For a movie where each frame is a cylindrical projection the viewĭirection can be rotated horizontally during playback.ĭue to changes in High Sierra and Mojave, the automatic reading of 'default.data' no longer seems Image projection, for example, for a fisheye image the movie can be rotated about the

The exact navigation that is appropriate depends on the input

In addition to the realtime warping, the application allows navigation while Many applications for this and some of them will be discussed below, the main reason forĭeveloping this was for movie playback in fulldome (eg: planetarium environments) whereĪ spherical mirror is used to distort the fisheye frames The movie is played and distorted on the fly.
