Note about the files formats : 1. commonname.fab and name.fab desc : Contains the commonly used stars names. type : ascii file, fields separated by | (pipe), end of line is CR ('\n') line example : 62956|Alioth line format : HPnum|Star_Name - HPnum : (unsigned int) Hipparcos catalog star number - Star_Name : (string) The name string without spaces. The '_' will be replaced by space in the program. 2. constellationsart.fab desc : Contains the constellation art info : i.e. for drawing of mythologic figures. type : ascii file, fields separated by SPACE, end of line is CR ('\n') line example : Lep lepus_m 104 57 24305 90 29 24845 33 42 27288 line format : ConstRef TextureFile x1 y1 HP1 x2 y2 HP2 x3 y3 HP3 - ConstRef : Short international name abreviation in 3 characters, first char in Capital letter - TextureFile : Texture file name without the extension (no space character). The texture file has to be in the stellarium texture directory. - x1 y1 hp1 (respectively 2 and 3) : the x and y position of the matching star with hipparcos number hp1 (respectively 2 and 3) on the texture image. The values are in pixels with the (0,0) in the upper left corner. Note : the associated texture file must be in png format and have no alpha channel. The drawing background must be black. 3. constellationship.fab desc : Contains the constellations lines shape. type : ascii file, fields separated by SPACE, end of line is CR ('\n') line example : And ANDROMEDE ANDROMEDA 3 9640 5447 5447 4436 4436 3881 line format : ConstRef ConstCommonName ConstInternationnalName NumberOfSegments seg11 seg12 seg21 seg22 etc... - ConstRef : Short international name abreviation in 3 characters, first char in Capital letter - ConstCommonName : Commonly used name (currently in french!) - ConstInternationnalName : The latin internationnal name. - NumberOfSegments : the number of segments in the shape. - segx1 segx2 : the hipparcos number of the stars 1 and 2 joined to form the xth segment. 4. courierfont.txt and spacefont.txt desc : contains the characters position on the font texture. type : ascii file, fields separated by SPACE, end of line is CR ('\n') first line format : CourierFont LineSize 21 - Font Name - LineSize s : s is the maximum character height. other lines example : 065 02 2 14 21 0 other lines format : ascii# x y w h s - ascii# : ascii number of the character - x y : position of the upper left corner of the character in the font texture (in pixel). - w h : width and height of the character on the texture - s : space to add at the end of the char when displaying. 5. messier.fab desc : Contains the nebula list (not only messier) type : ascii file, fields separated by SPACE, end of line is CR ('\n') line example : 1952 RS 05 34.5 +22 +01 8.2 06.0 0 M1_-_Crab_Nebula m1 lines format : NGCnumber NebulaType hh min.mm deg min.mm mag size texRotation Name TexName - NGCnumber : NGC catalog number - NebulaType : TODO and change.. - hh min.mm : Right ascention hour and minutes and tenth of minutes - deg min.mm : Declinaison in degree min and tenth of minutes - mag : magnitude - size : angular size in arcminute - Name : Nebula name with spaces replaced by '_' - TexName : texture file name. png file without alpha chanel. 6. name.txt desc : More info about stars, not used anymore. 7. ssystem.ini desc : Solar system bodies informations. type : ini file. One section per body. Section example : [io] // Section name, has to be unique name = Io // Body name parent = Jupiter // Body parent radius = 1821. // Radius in km halo = true // Do we have to draw a small halo like a star? color = 1.,1.,1. // Halo color tex_map = io // Texture map file without extension (has to .png) tex_halo = star16x16 // Halo texture file lightning = true // Compute shadow on it albedo = 0.61 // Body albedo (how it reflects light) range 0 to 1 rot_rotation_offset = 220.8 // For texture alignment rot_obliquity = 0.0 // Planet Obliquity (rotation axe inclination relatie to the orbit plane) coord_func = ell_orbit // Define the coordinate computation funcion : can be a custom func or "ell_orbit" orbit_Epoch = 2443000.00038375 // Ell_orbit calculation parameter orbit_Period = 1.769138 // " " orbit_SemiMajorAxis = 421600 // " " orbit_Eccentricity = 0.0041 // " " orbit_Inclination = 0.040 // " " orbit_AscendingNode = 312.981 // " " orbit_LongOfPericenter = 97.735 // " " orbit_MeanLongitude = 106.724 // " " 8. landscape.ini desc : Landscape skins descriptions. type : ini file. One section per landscape. Note : There can be 2 landscape types, the ones made from a fisheye picture and the ones made from many smaller textures. The fisheye textures must be centered on the zenith, north on the bottom. Section example for a fisheye : [palm] // Section name name = Palm // Landscape name type = fisheye // Type = fisheye maptex = landscapes/horizonalpha512 // Fisheye texture file name texturefov = 210 // Field of View covered by the texture (180 = half dome, 360 = full sphere) author = Gérard_Dupontd // Author name
