Tiny planet in photoshop6/21/2023 ![]() ![]() Push the latitude more than 180 degrees and you get a tunnel instead! View original panorama. Super sampling: option to average 4 or 9 samples per pixel to smooth details where the image is shrunk. Twist: twist the image by an amount proportional to its distance from the centre.īulge: can create some crazy distortions. Wrap effect: wrap the projection as you zoom into the image from planet to tunnel. Zoom: has the same effect as the field of view. Try pushing the latitude above about 180 degrees to transform the planet into a tunnel! Longitude and latitude offset: positions the projection eye. Best results are often obtained when the input image size is at least twice the output size.Ĭenter point: pan the image to centre the area of interest. Output image size: the final output size. When using within PBT you can use an image up to 4096x4096 pixels to create the highest quality results. Input image size: must be set to exactly the same width and height of the source panorama in order to get a seamless result. Note, you need to have the Pixel Bender Plug-in for Photoshop CS5 installed first.Īfter Effects: Copy the LittlePlanets.pbk file into the Plug-ins/Effects folder for your installation.įlash: There is an example Flash file used to create the movie above. Photoshop: Copy the LittlePlanets.pbk to 'Pixel Bender Files' folder within your Photoshop installation directory. PBT: Just open the LittlePlanets.pbk file, choose a source panorama image and hit 'Run'. See the Pixel Bender Technology Center for details on setting it up for your system. The Little Planets plugin will work with Adobe Photoshop, After Effects CS4+ or directly using the free Pixel Bender Toolkit (PBT). ![]() Press any key to change the panorama image. Which relate to the pixel x,y positions via:Ĭlick and drag your mouse in the Flash movie below to change the longitude and latitude of the viewing point. ![]() R is the radius of the sphere, which controls the zooming effect. The parameters Φ 0 and λ 0 are user controlled and effectively set the projection point viewing position (try clicking and dragging the Flash demo below). Φ is the latitude and λ is the longitude. It is conformal, which means that it preserves angles locally (note the grid lines still cross each other at right angles) although it doesn't preserve areas or distances.Īs we already have the colour of each longitude and latitude point on a sphere from the equirectangular panorama the inverse stereographic projection formulas are used, as described by Mathworld. Stereographic projection is a mapping that projects a sphere onto a plane, as illustrated with the world map below. Luckily there is a huge selection of creative-commons licensed panoramas on Flickr we can start playing with. If you want to create your own a few tutorials have been written on the subject. ![]() 1024x512 pixels.Ĭreating equirectangular panoramas is quite an art. A proper equirectangular panorama should be twice as wide as tall, e.g. For any longitude or latitude position on a sphere we can retrieve the colour directly from the corresponding x,y coordinates on the panorama image. This is an image where the x-axis corresponds to the longitude around a sphere (0-360 degrees) and the y-axis is the latitude (-90 to 90 degrees). To generate these images we start with a spherical ( equirectangular) panorama. It is possible to seamlessly move from a birds-eye view in the sky to that of a bug on the ground! Published on 17 June 2010 Little planets are created by applying a stereographic projection to a spherical panorama. ![]()
