Discover a new way to see your panoramic images.

Everyone loves panoramas but they are always in the same format and have the same look and feel. Panogaea changes everything by giving you control on how to manipulate and distort your panoramas to create fantastic new images.

Panogaea’s blazingly fast image processing algorithms are enabled by a combination of leveraging the computational power of your graphics card and by employing finely-tuned multithreaded algorithms. Panogaea enables realtime manipulation of large panoramic images and takes your spherical panoramas to the next level: letting you cascade an arbitrary number of distortion mappings together while you see the results live as you interactively vary their parameters.

Panogaea can load and save images in virtually every 8 or 16 bit image format.

Although Panogaea was created with spherical panoramas in mind it can be used to manipulate and distort any kind of digital photograph.


  • Why do I see a blank image after loading an image file?
    • The software is trying to render an image to the screen that is larger than the graphics card can support. The solution is to reduce the “Image Scale” parameter in the preferences window until the image renders correctly. Support for this bug will be addressed in the upcoming V1.2 update.
  • Are there plans for Panogaea on other operating systems?
    • Yes there are. The first will be a version for iOS with plans for later in 2011.
  • Do I need a computer with a separate graphics card?
    • No. Panogaea can run on the integrated graphics on older Mac laptops as well as on the newer 13″ MacBook pros. Having a fancy graphics card will of course help and will allow you to increase the size of the image rendered to the screen. In the absence of a graphics card Panogaea will run on the CPU alone but performance will degrade.
  • How much memory is required to run Panogaea?
    • This depends on the size of the image being processed but generally the more memory the merrier, especially when saving an image to disk. When saving Panogaea can accelerate the processing by using all available CPU processors and cores, in which case the bottleneck can be the amount of RAM available. If there is insufficient RAM the images will simply take a longer to save. For example, Panogaea will use about 480MB RAM when processing a 50 megapixel panorama. The memory use will increase to about 2GB when saving the file to disk.

  • Known Bugs
    • If you are experiencing a problem where you see a blank (grey) window in place of seeing the image then the software is trying to render an image to the screen that is larger than the graphics card can support. The solution is to reduce the “Image Scale” parameter in the preferences window until the image renders correctly. This bug will be fixed in an the upcoming V1.2 update. You can confirm that this is indeed the bug by clicking and dragging in the image window. After the software has time to recompute the image using the CPU instead of the GPU it should render the image correctly.
      A bug where dragging an image to the dock icon causes a crash. This bug has been now fixed in the upcoming V1.2 update.
      A bug where the GPU incorrectly reports the GPUs capabilities to the software. The effect is that the app launches normally but the image window is made very small after opening an image. This bug has been fixed and the fix is in the upcoming V1.2 update.


    The magic of Panogaea is the mappings. The magic behind the mappings is the mathematics. The equations for these mappings were worked out long, long ago and have been primarily applied in cartography. Below you can find links to descriptions for some of the mappings used in Panogaea.

    Equirectangular Projection

    The equirectangular projection (wikipedia) is the most commonly used projection in panoramic photography. Essentially this projection maps the surface of a sphere to a plane whose aspect ratio is 2 to 1.

    Quaternion Rotation

    Quaternions (wikipedia link) are a mathematical number system that extend the concept of complex numbers to 4 dimensions. Aside from their somewhat complicated algebraic properties quaternions provide an incredibly simple and computationally fast way to perform three dimensional rotations. (wikipedia)

    Stereographic Projection

    The stereographic projection (wikipedia) is a mapping from the sphere to an infinite plane. Used in conjunction with a quaternion rotation of the sphere this mapping can produce fantastic mini-planetoid-type images.

    Azimuthal Equidistant Projection

    The equidistant projection (wikipedia) is the type of projection commonly found in fisheye lenses which maps the hemisphere to a circular image. Panogaea has extended the mathematics a bit to project the a full sphere to a circular image.

    Pierce Quincuncial projection

    The Pierce Quincuncial projection (wikipedia) is a combination of the stereographic projection and the Schwarz-Christoffel conformal mapping. (wikipedia) The Schwarz-Christoeffel mapping maps the unit circle to the regular n-gon.


    3.1.11 – Version 1.4 is available right now. The V1.4 update includes:

    All documentation has been moved into an Apple Help Book, available from the Help menu.
    Several UI modifications for clicking and dragging on images.
    New algorithm for determining the rendered size of the image to the screen.
    Double clicking a row in the mappings table renders the image of the selected mapping.
    Fixes a bug when the circular mask is applied before some other mappings.
    Fixes a bug when a stereographic mapping is applied after an equirectangular stretch mapping.
    Many other under the hood improvements.

    2.10.11 – Version 1.3 is live on the Mac App Store. V1.3 focuses on several bug fixes.

    Fixes a memory leak when closing documents.
    Bug fix for images when an equidistant mapping is applied after a stereographic mapping.
    Bug fix for images when a crop mapping is used before or after an equidistant mapping.
    Bug fix for images when a cubic bump mapping is applied to images whose width is smaller than the height

    1.31.11 – Version 1.2 is live on the app store.

    Fixes a bug when dragging and image to the dock icon could cause the application to crash.
    Adds a user preference to disable the GPU for running on older machines without sufficient graphics cards.

    1.19.11 – Version 1.1 is available for download now on the Mac App Store.

    V1.1 uses an improved image processing engine that increases the image quality of both images rendered to the screen as well as full-resolution images when saving to disk. The new engine is also faster too. Since the update is free to all registered users, V1.1 is better, faster and cheaper!
