  • About Fisheye projection

    Hi
    I am from Turkey.
    We are a company that produce Optic-mechanic Planetarium machines and digital planetarium presentation system include
    warping,correction and blend operations.
    We want to able to show World Wind program on the dome.
    So we need fisheye projection view to "World Wind" . In the future it will be possible?

    Thanks.

    World Wind .Net or Java? Or doesn't matter which one?
    (.Net development is pretty dead... (or in hiatus)

    Anyway, this company displayed imagery from WW.Net (or from another app based on it) on a spherical display http://www.globalimagination.com/products.html I think that Chris (cmaxwell) may know more...

      Essentially in .Net but if is not possible then in Java.

        Hello Asaf,

        What is the best variant of a fisheye type lens for a fisheye projector or a mirror dome? We're doing CATOPS lab project with the students from the University of Kentucky College of Engineering. Giving them a simple task now to write my essay today explaining how fisheye projectors work.

        Also using Shira Universe version 3.8.5

          Hi! Within the framework of this scheme, a single-channel system is based using a special lens called "fisheye" ("fisheye"). In this case, the projector is installed vertically in the center of the dome and, thanks to optics with an angular field of 170-180 , provides a projection onto the entire spherical screen. Despite the seeming simplicity of the solution, the technical implementation of such an optical scheme turns out to be rather complicated. So, a simple way to install a "fisheye" attachment on a standard projector lens gives a sharp deterioration in quality for a number of indicators. In addition, not every projector is suitable for this purpose. Replacing a standard lens with a specially designed one (unfortunately, manufacturers of available projectors do not offer such lenses) gives a good result, but is an extremely expensive and complicated process. In this case, the quality of projection is certainly higher in comparison with a mirror system. This is clearly visible to any user. As well as the undoubted ease of use of such a projection system: - no setup and preparation; - wardrobe trunk with one button.
