What it does How to Install Quick Start Projections Polyhedra Other Controls Memory dots Globemaking Brick spheres Cube maps FAQ Versions How to Purchase Questions |  | Flexify 2 What it does Flexify is a plug-in filter for paint programs. It warps full-sphere photos -- those showing a full view of a scene in every direction -- into new shapes that are more attractive or useful. It can also transform maps. How to install Illustrated installation instructions are online. To use this software, you need a paint program which accepts standard Photoshop 3.02 plugins. Just put the plug-in filter into the folder where your paint program expects to find it. If you have Photoshop, the folder is Photoshop:Plugins:Filters or Photoshop:Plug-ins. You must restart Photoshop before it will notice the new plug-in. It will appear in th e menus as Filters->Flaming Pear->Flexify 2. Most other paint programs follow a similar scheme. If you have Paint Shop Pro: you have to create a new folder, put the plug-in filter into it, and then tell PSP to look there. PSP 7: Choose the menu File-> Preferences-> File Locations... and choose the Plug-in Filters tab. Use one of the "Browse" buttons to choose the folder that contains the plug-in. The plug-in is now installed. To use it, open any image and select an area. From the menus, choose Effects->Plug-in Filters->Flaming Pear->Flexify 2. PSP 8, 9, X, and XI: Choose the menu File-> Preferences-> File Locations... In the dialog box that appears, choose Plug-ins from the list. Click "Add." If you are using PSP 8 or 9, click "Browse". Now choose the folder that contains the plug-in. The plug-in is now installed. To use it, open any image and select an area. From the menus, choose Effects->Plugins->Flaming Pear->Flexify 2. Quick start When you invoke Flexify 2, a dialog box will appear:
To get a quick idea of what Flexify does, load a full-sphere panoramic image into your paint program (there's a small example panorama here). If the image is circular, the selection should graze the edge of the circle. Invoke Flexify, and tell it what kind of input image you're using via the "Input" popup menu. Choose a different projection from the Output popup. Click the dice button a few times until you see a result you like; then click OK. Flexify's capabilites and controls are explained below. |  | selection should graze the edge of the circle
Projections |  |
A projection is a way of unwrapping and warping a spherical surface so that it will lie down flat. It's like making a flat map of the Earth – you have to make a choice about how to deform shapes. Flexify can accept as input spherical panoramas in any of fifteen projections and can output them in more than fifty. Some of the projections are practical; some are weird and are meant to emphasize the bizarre, vertiginous nature of ultra-wide-angle photography. Flexify can output these projections: |  |
name |  | remarks |  |  |
equirectangular a.k.a. cylindrical equidistant or plate carée |  | The panorama fits into a rectangle. Meridians are vertical, parallels are horizontal, and the north and poles are stretched out to lines at the top and bottom. Scanning panoramic cameras produce this kind of image. Not the same as Mercator. |  |  |
mirror ball |  | The reflection seen in a mirrored ball |  |  |
polar a.k.a. azimuthal equidistant |  | Angular distance from the center of projection increases uniformly toward the edge. |  |  |
orthographic |  | The image sphere as seen from the outside |  |  |
tetrahedron |  | An unfolded 4-faced shape |  |  |
cube |  | An unfolded 6-faced shape |  |  |
octohedron |  | An unfolded 8-faced shape |  |  |
dodecahedron |  | An unfolded 12-faced shape |  |  |
icosahedron |  | An unfolded 20-faced shape |  |  |
Hammer |  | A 2:1 wide ellipse |  |  |
Werner |  | A heart-shaped projection |  |  |
sinusoidal a.k.a. Sanson-Flamsteed |  | A pointy shape |  |  |
rectilinear a.k.a. gnomonic |  | Like a regular view from a normal lens. Straight lines stay straight. The FOV slider controls the zoom, which can go all the way to a 180° field of view. |  |  |
hyperbolic |  | Produces views balancing naturalness with vertigo. The FOV slider controls the zoom, which can go all the way to a 360° field of view. |  |  |
stereographic |  | Like hyperbolic but with less distortion of scale and shape. The FOV slider controls the zoom. |  |  |
cylindrical |  | This is the format needed for some panorama viewers, including QuickTime VR. The view is infinitely stretched toward the top and bottom, so the vertical view is determined by the rectangle's proportions. |  |  |
Wetch |  | An unusual projection with a finite height and infinite width. The FOV slider controls the zoom, which can go all the way to a 360° field of view. |  |  |
pinwheel |  | Polar with a swirl. |  |  |
lozenge |  | A wide diamond shape with a crease at the equator. |  |  |
square |  | A square full of creases. Good for scenes containing lots of straight lines. |  |  |
curvy |  | Labrys-like shape with limited distortion. It's the central portion of a mirror ball projection. |  |  |
goggles |  | Goggle-shaped view which presents the whole sphere in a style like the hyperbolic projection, but with less extreme size changes. |  |  |

spikeball |  | A tetrahedron 5-compound, and Flexify's most difficult-to-construct polyhedron. It prints out as ten sawtooth shapes. Each sawtooth folds up into a pair of peaks, and you assemble them all to get the finished shape. Because the shape is so complex, you should start with a very bold, simple picture. |  |  |
brick preview |  | The image sphere built from Lego® bricks. Flexify can create builiding plans for these spheres. It's explained in the brick sphere part of this guide. |  |  |

Flexify can accept some of the above projections as input: equirectangular, mirror ball, polar, orthographic, cylindrical, ellipsoid, stereographic, Mollweide, gores:12, Robinson, Mercator, Lagrange, Hammer, Winkel Tripel, and equal-area cylinder. Some more projections are for input only: |  |
ellipsoid |  | A frontal view of a security mirror. The major axis to minor axis ratio is 1.18:1. |  |  |
circular fisheye 180° |  | A circular image showing a 180° field of view across its diameter. |  |  |
fullframe fisheye 180° |  | A rectangular image showing a 180° field of view across its diagonal. The rectangle may have any proportions. |  |  |
one cube face |  | A square showing a 90° rectilinear view. |  |  |
tiling cube face |  | One cube face with all edges alike and symmetrical so that six tiles can seamlessly cover a sphere. You can make these with MakeCubeTile or MakeIsoCubeTile. |  |  |
half-equi |  | The left or right half of an equirectangular image. If your input image is too big for Flexify, you can use this mode to process it in halves. |  |  |
Nicolosi |  | A Nicolosi projection, a popular globular form found in antique world maps. |  |  |
quarter-equi |  | One-fourth the width of an equirectangular image. |  |  |
mylar |  | The reflection in a silver balloon. The major axis to minor axis ratio is 1.55:1. |  |  |
gores: 12 radial |  | Twelve half-gores, a form sometimes used by the US Geological Survey. |  |  |
View |  |  |
You can change the center of projection -- the point in the input image that winds up at the center of the output. Latitude moves the center of projection north and south. Longitude moves the center of projection east and west. Spin spins the view around the center of projection. |  | an off-center hyperbolic view |
Flexify can set the center of projection automatically in three ways. The reset button sets latitude, longitude, and spin to zero. This gets you back to the normal view. The axis button sets latitude, longitude, and spin to multiples of 90°. This usually gives symmetrical-looking views. The dice button generates totally random views. Click it as much as you want to see different effects. |  | reset axis dice |
Polyhedra |  |  |
Flexify has some projections that you can print, cut out, fold, and glue together to make a three-dimensional printout of your panorama. If you use a map of Earth as your input image, you can make a crude globe. Tabs sets the width of "glue tabs" that make the polyhedron easier to glue together. The Tab color button sets the color of the tabs. |  | color button |
The Faces checkbox shows each face of the polyhedron in a single color, to make it clearer how the shape should be folded together. |  |  |
The Export Faces button offers two ways to export a polyhedron. You can write a multi-layer Photoshop document with one face of the current polyhedron on each layer. Extra tabs will be added to each face so that everything can be glued properly. You can also export a 3D model in OBJ format. If your image is 32 bits per channel, then each face will be written to a separate document. If you export an OBJ model, its JPEG texture map will still be 8 bits per channel. Pepakura Designer is handy for editing cut-and-fold paper models. |  | export faces |
Other controls |  |  |
The Flip checkbox flips the input picture left-for right. If you are starting with a mirror-ball photo, this will correct backward text. The Sharpen slider makes the image crisper. Sharpening is done in the output image space, so you get the right result even where the picture is strongly warped. The Background color button lets you choose a background color. If your color doesn't show up, turn off Transparent gaps. The Preview menu improves the appearance of the preview at the expense of speed. The Grid menu places a latitude-longitude graticule over the output. The Transparent gaps checkbox tells Flexify what to do with undefined regions of the input. When this is checked, such areas appear transparent (or black if you're working in the background layer). When it's unchecked, they get a solid color halfway between the background and tab colors. Transparent gaps also makes the border, if any, around the result transparent. The Indicatrix checkbox draws shapes which, on the image sphere, would be circles. It's good for checking how distorted the output is. The Anamorph checkbox produces a special distortion. Ordinarily the image sphere is meant to be viewed by an observer at its center; you could build globe with the image printed on the inside, and it would appear in correct perspective to an observer at the globe's center. When checked, Anamorph moves the viewpoint to the surface of the sphere. You could then build a globe whose inner picture appears correct when viewed through a hole cut in its surface. This viewing point appears as a pinched singularity in Flexify's output. The Edges checkbox draws a black outline around each region of the result. It's good for clarifying the fold lines for polyhedra The De-halo checkbox guarantees that halos don't appear along contrasty edges, but this comes at the cost of making the whole image slightly softer. It's useful in HDR images where bad halos can appear at the edge of the sun or other bright lights. Plus, % and minus buttons: if the selected image area is bigger than the preview, these buttons let you zoom in and out. You can move the preview by dragging it around; your cursor will turn into a hand. Auto Preview When this box is checked, the preview automatically updates whenever you move any control. Turn it off if you want to save time. |  |  |
Load preset Flexify comes with some presets, which are files containing settings. To load one, click this button and browse for a preset file. Save preset When you make an effect you like, click this button to save the settings in a file. Undo backs up one step. Brick button shows settings for the brick sphere, explained below. Glue lets you combine the result image with the original, instead of replacing it. The next-glue button advances to the next glue mode. Send to photo manager Sends the result to iPhoto (on Macintosh). Export to PSD Renders the result to a a .psd image file, which can have custom dimensions. Info Briefly explains of the controls. Three more buttons: OK Applies the effect to your image. Cancel Dismisses the filter, and leaves the image unchanged. Register Allows you to type in a registration code and remove the time limit from the demo. |  | load preset save preset undo brick button export to PSD next glue info send to photo manager |
Memory dots |  |  |
Although you can save your settings permanently to files, you can also stash settings in memory dots. Click an empty dot to stash the current settings in it. Click a full dot to retrieve its settings. Hover the mouse over a dot to see what it contains. Option-click to erase a dot on Macintosh. Right-click to erase a dot on Windows. If a dot is orange, Flexify's currently using that dot's settings. Dots remember their contents until you erase them. If you'd rather make a temporary dot that forgets when you exit Flexify, control-click it. Temporary dots are square. When you start Flexify, it puts the starting settings in a temporary dot. That way it's easy to start over without exiting the plug-in. |  | memory dots empty full current temporary |
Globemaking Flexify can warp maps into new shapes for making globes. You can use any of the polyhedron modes, explained above, to make faceted fold-together globes. You can also make a conventional round globe. First, get a spherical object to use as a form. Traditionally, a plaster sphere is used, but a toy ball will do. It has to be exactly spherical: measure its girth in several places and verify that all measurements are the same. Next, use Flexify to make "gores" -- the lens-shaped strips of map that form a globe's surface. Print these out so that the width of the gores is equal to the diameter of the sphere. Glue the gores onto the sphere, carefully making them conform to the curved surface. The Tabs slider adds solid-colored "glue tabs" that make the gores easier to glue together. It also fattens the mapped part of the gores slightly too, so that you need not align them perfectly on the sphere. The Tab color button sets the color of the tabs. If you don't want tabs, but do want the gores to be slightly fattened, set the tab color to the same as the background color. Flexify can also acccept gores as input and turn them into a conventional map. Use the input mode "gores:12". |  | 12-gore shape color button |
Brick spheres Flexify can create plans for building an image sphere from Lego® bricks. Use the output mode called 'brick preview' to see what you can build. To change settings, click the brick button. A new dialog box will appear. Layers To correct for the proportions of the bricks, Flexify plans a sphere with a diameter 6/5 of the height. For best results choose a height that's a multiple of 5. Plates Builds the sphere from 1/3 height plates instead of bricks. Colors The best input images have vivid colors and strong, simple shapes. For output you can choose among 12 colors: black, blue, brown, green, dark grey, light grey, red, sand red, tan, white, yellow, and sand green. If your input image is doesn't cover the whole sphere, light grey bricks will represent the undefined regions. Results You can make three kinds of output: -a multi-layer Photoshop document where each layer of the document is the plan for one layer of the sphere - an LDraw model - a text file with counts for each color of brick In the Photoshop document, parts that aren't visible from the outside are marked with black dots, so you can substitute other colors there. The sphere plan is hollow and just thick enough form a solid surface so you'll need to build supports inside as you go. The plan doesn't specify exactly what bricks to use, just what colors go where. There are some related links below. |  | brick preview brick button |
Cube Maps Flexify can split a panorama into six cube faces. Some panorama viewers want this format, and it's often used to make "sky boxes" in 3D action games. Click the cube map button and a new dialog box will appear asking for the size of the faces. Flexify will write six Photoshop documents containing the cube faces. |  | cube map button |
Frequently Asked Questions I want to make maps and globes with Flexify. Where can I find suitable input maps? Here are some places to start looking: NASA's Blue Marble imagery Virtual Terrain project links to many map sources NASA Jet Propulsion Lab maps of most Solar System bodies Ars Technica earth map Living Earth maps of Earth, Moon, and Mars Björn Jónsson's planetary maps LunarCell synthetic worlds You can use Flexify's polyhedron and gore modes to make cut-and fold globes. How do I make a spherical photo without expensive special equipment? Get a plain silver spherical Christmas-tree ornament and photograph it. How do I improve photos of ornaments? Panoramas made with the mirrored-ball technique always have a flaw at the point opposite the camera. You can either paint this out, or you can photograph the ball twice from two locations about 90° apart around the ball's equator. Unwrap both reflections; their flaws will be in two different places. Use the good part of one image to replace the flaw in the other. Since the reflection in the ball contains the whole scene, the sun or another light source will probably appear in it, and this can cause your camera's auto-exposure to darken the whole picture. To avoid this use a manual exposure setting appropriate for a typical part of the scene. The best ornaments to use are blown-glass ones from eastern Europe, but there are other kinds of mirrors you can use: Gazing balls. These are garden decorations originally popular in Victorian England, and they can be found at some garden-supply stores. Safety/security mirrors. These are the dome-shaped mirrors sometimes seen at busy corridor intersections at airports and warehouses. These are usually not hemispheres but ellipsoids with proportions of about 1 : 0.85, so you should use the 'ellipsoid' input mode. Large steel ball bearings. The makers of HDR Shop have hints on where to get them. Hemispherical mirrors from "whole sky cameras." These are hard to find since meteorologists now use fisheye lenses for sky photography. Large steel or copper mixing bowls don't give sharp reflections, but they are inexpensive and can produce soft, tinted views with streaky blurs around the highlights. Using a mirrored ball you can make a wide horizontal view panorama with no flaw. Place the ball on the ground and photograph it from directly above; or hang it from something and shoot it from below. Use a zoom or telephoto lens to get far from the mirror and minimize the size of the camera in the picture. To enable a telephoto lens to focus closer, use it together with a close-up lens. That this will reduce depth of field, making focussing trickier. What is the difference between equirectangular and Mercator? An equirectangular image shows the whole sphere, usually in a 2:1 wide rectangle. The north and south poles are stretched out to lines at the top and bottom, and the lines of latitude and longitude make a uniform grid of squares. A Mercator projection shows most of the sphere, but not the poles or nearby regions, because the complete projection is infinitely tall. The lines of latitude and longitude form rectangles that stretch taller the further they are from the equator. Although Mercator projections are notorious for making Greenland look as large as South America, they have two useful properties. They are conformal, which means angles are accurate within small regions. And they show lines of constant compass bearing as straight lines. These lines, known as rhumb lines or loxodromes, are useful in air and sea navigation, which is why Mercator maps are still used. So: Equirectangular images are good for panoramas and spherical texture maps. Mercator maps are good for sailing across an ocean. How do I make a cylindrical QuickTime VR panorama? Make an cylindrical projection, then turn it sideways so the bottom is on the right. Convert it with QTVR Make Panorama 2(Mac) or VRMakePano (Windows). You can find more detailed instructions here. How do I make a cubic QuickTime VR panorama? Make an equirectangular projection that's exactly twice as wide as it is tall, then convert it with MakeCubic PPC (Mac) or PanoCube (Windows). What other panorama viewers are there? Many; click here for a list. How else can I (ab)use Flexify? Straighten out the horizon in panos shot off-level. Warp an HDR lighting environment so it's easier to paint out the tripod. Use it on non-panoramic photos to make them weird. Distort the same image twice or more in a row to make it weird. Photograph safety mirrors and security-camera bubbles in public places. De-warp the reflections to see what they see. Extract a normal (rectilinear) view from the input. Take a photo of a spherical object like an orange or the Earth and see what it would look like from a different point of view. Use orthographic input and orthographic output. Make many-sided dice for role-playing games. Use only polyhedra whose sides are all the same shape; otherwise the die will be biased. Make weird graph paper: start with a blank white image and turn the grid on. What are some panoramic photo resources on the net?

Changes the Gilbert projection so it reacts more usefully to nonzero latitude settings. Version 2.2.2 September 2007 Adds quick globe and equal squarea projections. Improves "best" mode results in strongly anisotropic regions. Removes speckled pixels that sometimes appeared on one e dge of previews in "better" mode. Some polygonal projections now show colored faces better. Version 2.2 August 2007 Adds antialiased (smoothed) output and preview. New input modes: Hammer, Winkel Tripel and equal-area cylindrical. New output modes: cross, double Guyou, wide rect, semicircle, ellipse, Reuleaux 1, Reuleaux 2, Reuleaux 4, Reuleaux 8, octreleaux, zigzag, chevron, monozag, 3-malta, 4-malta, 5-malta, 6-malta, Gilbert, stereo twice, stereo thrice, Adams diamonds, equal-area cylinder. No more missing graticule lines. Graticule slid over one pixel to the proper location. Added the Tissot indicatrix.Gores:6 output removed; use gores:multi instead. Version 2.10 June 2007 Adds the shuriken output mode. Fixes a Windows problem where the plug-in wouldn't remember its registration when it was installed in one user account but activated in another. Fixes a Macintosh problem where the plug-in could have bad settings or crash when installed on a machine for the first time. Version 2.09 May 2007 Adds 19 new output modes and the Lagrange input mode. Replaces gores:36 with the more adjustable gores:multi. Impr oves the appearance near the poles in most conformal projections: no interrupted graticules, no top-to-bottom color wraparound. Version 2.08 February 2007 Adds new output modes: thorn levo, unFish, Lagrange plus, Adams 1, Adams 2, trecunx, quadracunx, quincunx, sexacunx, heptecunx. Smoothed out creases in thorn mode. Fixed poor antialiasing in the 4/12/24/60/70 views modes. Fixed a probem where the latitude-longitude grid would sometimes not appear, and de-cluttered the grid near the poles. More memory dots. Windows PSD export can have a custom size. Mac presets have custom Finder icons. Version 2.06 December 2006 Adds new output modes: semistereo, thorn, Lagrange 3/4, squoculus, and box. Universal binary on Macintosh. More memory dots. Exported HDR files can be layered. Exported OBJ files fixed to work with Photoshop CS3. Version 2.05 May 2006 Adds exportation of PSD images with custom size; new grid option. New input modes are 12 gores: radial and Mercator. Fixes a problem under Windows where the software could crash on HDR images. Version 2.04 May 2006 Adds the equi tall projection. Fixes a problem where the software could forget its registration. Version 2.02 March 2006 Adds IPTC keywords and color profiles to all exported images. Version 2.0 March 2006 Adds 32-bit high-dynamic-range capability. Can handle images up to 30,0000 x 30,000 pixels, given enough hard drive space. Adds the quarter-equi, Robinson, and mylar input modes; rind 1, rind 2, rind 3, tunable ellipsoid, tunable egg, 4 four views, 12 views, 24 views, 60 views, 72 views, and Robinson output modes. Memory dots, info button, exportation of 3D models. Changes 'transparent gaps' to make backgrounds transparent too. Equirectangular output is now always 2:1.Cube maps now always export to six separate files. Adds Anamorph and De-halo controls. Exported PSD files now have color profiles. The Mac version lets you use Adobe's color picker. Version 1.99 September 2005 Adds the stereographic, hyperdouble, hypertriple, Mercator cross, Mercator star, and Lagrange projections. Fixes tiny flaws in the grid lines and adds a glue mode. Better previews in the file chooser. The Mac OS X version adds the iPhoto button. Version 1.98 May 2005 Faster. Adds the Mercator and umbrella projections.
