These may be upright domes such as these, planetariums such as this, and even more exotic spherical environments such as these. For a movie where each frame is a cylindrical projection the view direction can be rotated horizontally during playback.Ĭalibration tool for dome projection using a spherical mirror and single projector.Īvailable for Mac OS-X”meshmapper” is a utility that allows one to create precise warping maps for projection systems using a single projector and a spherical mirror, a technique called variously “sphemir” and “mirrordome”. The exact navigation that is appropriate depends on the input image projection, for example, for a fisheye image the movie can be rotated about the pole while it is playing. In addition to the realtime warping, the application allows navigation while the movie is playing. There are many applications for this and some of them will be discussed below, the main reason for developing this was for movie playback in fulldome (eg: planetarium environments) where a spherical mirror is used to distort the fisheye frames of the movie. The movie is played and distorted on the fly. “warpplayer” is a Mac OS-X application that takes a QuickTime movie and a description of how to distort each frame. QuickTime movie player with realtime warping and navigation Intended primarily for fulldome projection using a spherical mirror. The best results can be achieved by a dome screen, however the cylinder and box screens setups produce just as good results. This version supports dome (truncated en full), cylindrical and box (room) screens. It uses “off-the-shelf” spherical mirror mostly called “Safety mirrors” or “Security mirrors”.Different screens can be used to project the fish eye scene. Immersive Display Designer is a tool that provides a intuitive virtual environments for designing immersive display solutions and applying the solutions in a flight simulator environments.The main advantage of this idea is that it does not require expensive projector setups capable of projecting fish eye scenes. Pre-warp fisheye images for spherical-mirror movie making. ![]() An example of such a mesh is given here: xyuv.data.Ĭommercial ($45USD). The description of how a frame is warped is defined by a so called warp mesh. tgawarp (also includes jpgwarp)įull dome projection using a spherical mirror requires that the fisheye frames be distorted such that the result on the dome looks correct.This can be done in realtime using a locally developed QuickTime player but it can sometimes be useful to prewarp the frames of a fisheye movie.Reasons for doing this include playback from non-Apple hardware or playback from a lower end platform that may not be able to support the warp-on-the-fly technique. Also note that some applications display images but will not display movies. The software listing below is only part of what is available for geodesic dome projection.
