This file is a Starry Night document. // Part 1 // Pano name - you see this in menus, etc. This should be unigue for each pano. // Change value="Earth Wellington" to a name that describes your image. For examplevalue="MyHorizon". The name you choose will appear in the drop box in the Horizon Options window. // Change value="00_Earth_Wellington.png" to the name of the PNG image you made and placed in the Horizon Panoramas folder. For example if you named your image "MyHorizon.png", change it to value="MyHorizon.png". // Both the image and text file must be located in the Horizon Panoramas folder. // Part 2 // Planet that panorama is associated with (in this case this panorama is only appropriate for the Earth) // Part 3 // In degrees, the height of the image. This value specifies the height of the image in degrees. A value between 45-55 is about right for most images. // Part 4 // If the image has an alpha channel that is set up with the sky having an alpha of 0 and the horizon an alpha of 1, // with alpha blending at the interface, we need to say Yes here, otherwise say "no" // Leave this value as yes if you added an Alpha channel. // Part 5 // These values are in the coord system that you pick out with ImageCoordSys // Part 5 // Think of ImageCentreDec as degrees Up and Down. // A value of -11.0 means that the centre of your image lies 11 degrees below Starry Night's formal horizon line. // SN's formal horizon line lies at 0 degrees Altitude as you may expect. // Use this value to adjust your panorama until it looks right against the sky. // You can even set this precisely by recording the actual rise or set time of a certain star/planet over a given obstacle in your panorama -e.g. a mountain peak- and set the ImageCentreDec so that it appears the same in SN. //Think of ImageCentreRa as Left and Right. Adjust this value if your image is facing towards the incorrect cardinal direction. // Part 6 // These are also in ImageCoordSys coordinate system. // They determine where the image will be. // If you're not sure do not make any changes here. // Part 7 // Adjusts the brightness of your horizon. The panorama brightness will be scaled with this value, up to a maximum of 1.0 (100%). If you want your panorama to appear half as bright, use a PanoBrightness value of 0.5 (50%). // Part 8 // Used during liftoff to draw a horizon nicely. Ignored for panos like the milkyway which are always far off. // Part 9 // Used during liftoff to draw a horizon nicely. Ignored for panos like the milkyway which are always far off. // the color is red, green, blue, with each value scaled 0 to 65535 // Part 10 // If preload is set, will load image on startup. // You can have multiple images preloading when the program starts. However, this will increase the time that it takes for Starry Night to load. // Ideally you only want one image to have a preload value of ‘Yes’, the one you use most often. // In addition, when Starry Night loads, the horizon that is displayed by default is the one whose accompanying text file was read first in alphanumeric order from the Horizon Panoramas folder. // If you want your panorama image to load first, give it a preload value of ‘Yes’ and name the text file so that it is listed first in alphanumeric order, such as Earth_00MyHorizon.txt. // Part 11 // ImageCoordSys values // kNoCoordinateSystem = 0, // kAltAzSystem = 1, // kGalacticSystem = 2, // kEclipticSystem = 3, // kCelestialJ2000System = 4, // kCelestialJNowSystem = 5, // kOrientationSystem = 6, // kSuperGalacticSystem = 7, // Part 12 // ImageTransferMode values // OpenGLState kNoState = 0, // kDefault = 1, // kStars = 2, // kTransparentAdd = 3, // kTransparentGlass = 4, // kOpaque = 5, // kShaded = 6, // kLighting = 7, // shaded with specular lighting // kShadedLine = 8, // kBillboard = 9, // For horizons, 4 (kTransparentGlass) and 5 (kOpaque) are // Part 13 // It's a panorama image; leave the value always as 360º.
