Discover A New Way To Explore Your Panoramas
distorting your mind, one panorama at a time
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.
Feel free to contact support with all your questions:
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.
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.
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)
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.
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.
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!

You Go Mountain was founded in 2010 with one objective in mind: to make sophisticated panoramic image manipulation simple, fast and fun. The founder of You Go Mountain, Kevin Gross is an optical scientist / applied mathematician / software developer / photographer who quit his job as a lens designer to devote time to developing Panogaea.
