1Celestia Revision History 2------------------------- 3 41.00 5* Initial public release 6 7 81.01 9* Added more realistic and aesthetically pleasing ring illumination function 10* Made planets project shadows onto their rings (requires multitexturing) 11* Detect and use ARB_multitexture extension 12* Some configuration parameters now read from a file 13* Support for multiple solar system catalog files 14* Split solar system files into solarsys.ssc and extrasolar.ssc 15* Added Help/License menu 16* Added simple camera orbit mode 17* Fixed up parsing and printing of catalog numbers--still kludgy though 18 19 201.02 21* Made Celestia icon appear in corner of window. Whee. 22* Fixed an extremely subtle numerical precision bug which manifested itself in 23 a number of ways: jittering when following small objects, incorrect 24 targeting of small objects with goto, occasional flashes when closely 25 approaching an object, and probably other things as well. 26* Reversed rotation directions when orbiting--it's much more intuitive now 27* Added an exponential dolly capability to the camera 28* Double-clicking will now center on the selected object 29* Fixed bug in elliptical orbit calculation 30* When orbits are displayed, the Orbit for the selected object is highlighted 31* Incorporated Scott Hudson's asteroid geometry data for Toutatis, Kleopatra, 32 and Geographos. 33* Fixed problems with disappearing labels and with misplaced labels for 34 extrasolar planets 35* Eliminated 'sticking' when mouse buttons released outside of Celestia window 36* Added Real Time option to Time menu 37* Reversed planet rotation direction so it's correct. Oops. 38* Added about a dozen extrasolar systems from Jean Schneider's catalog 39* Create two new textures for extrasolar planets 40* Moved Selection class outside of Simulation, as it's generally useful 41 42 431.03 44* Rotating the camera is now more responsive to mouse movement 45* 'Infinite mouse' hack allows rotating and dollying without having to pick up 46 the mouse and reposition the cursor in the window 47* Fixed z ordering for planets and satellites so small that they only appear 48 as points. Small satellites will no longer get obscured by planets they're 49 in front of. 50* Apparent magnitude calculation for planets now takes into account phase 51* At close range, stars are now rendered as textured sphere meshes. 52* Choosing stars by catalog number no longer selects a star even when the specified 53 star doesn't exist. 54* Added labels for stars; the list of labelled stars is read from celestia.cfg 55* Cleaned up vecmath.h, added consts and reference parameters where appropriate 56* Cleaned up StarNameDatabase 57 58 591.04 60* Start out at the moon instead of in deep space 61* Made picking of planets work properly for planets with disc sizes greater than one 62 pixel. 63* Added call to glDeleteTextures to Texture class destructor 64* Added bump mapping. Uses DOT3 bump mapping and only works on GeForce cards 65 right now. 66* Enabled user control of per-pixel lighting. 67* Menu checked state for label options synced with renderer state. 68* Added a context menu that appears when an object is right clicked. 69* Celestia now uses texture coordinates from 3DS files 70* Added 3DS model of Eros based on NEAR laser rangefinder data 71* Added 3DS models of Deimos, Phobos, and numerous other asteroids and 72 small moons based on Phil Stooke's models 73* Replaced TriangleList class with much more flexible VertexList 74* Introduced support for compressed textures; texture compression is specified 75 on a per texture basis in .ssc files. 76* Added a reverse time option 77* Added an OpenGL Driver Info item to the help menu 78 79 801.05 81* Made per-pixel lighting work for planets without bump maps too 82* Allow user control of magnitude of faintest visible stars 83* Added support for PNG textures 84* Improved console: enabled backspace, relocated text entry, code cleanup, ... 85* Corrected star positions by converting them from equatorial to ecliptical 86 coordinates. 87* Eliminated case sensitivity when selecting objects by name 88* New ring texture for Saturn with separate reflectance and opacity 89* Ring textures now specified in .ssc files instead of hardcoded 90* Implemented date/time selector dialog box 91* Changed the mouse wheel function from zoom to dolly. Zoom is now controlled by 92 shift left-dragging the mouse. For mice without wheels, control left-dragging 93 will dolly. 94* Fixed orbit and dolly functions to work in follow mode 95* Improved rendering of objects at close range: less clipping, extra sphere LOD. 96* Fixed bug that caused irregular objects to be displayed at half their actual size 97* ESC now cancels goto and follow instead of exiting app. 98* Fixed orbital calculations for planets so their positions are now closer to 99 reality. 100* Completed extrasolar planets database; it now contains all known planets 101 around normal stars 102* Mir! 103* MeanAnomaly field in .ssc files was incorrectly called TrueAnomaly; this 104 is fixed, and solar system parser now also accepts MeanLongitude in orbital 105 elements section. 106* Epoch can now be specified for orbital elements. Default is J2000. 107 108 1091.06 110* Made Alt+F4 exit the app. 111* Fixed text rendering to be pixel-accurate; labels and console text are now 112 crisper and don't have any missing pixels (need to test on more graphics 113 chipsets.) 114* Updated parser to handle negative numbers. Big oops. 115* Corrected errors and omissions in extrasolar planets catalog. 116* Added locations menu for saving and recalling favorite places. 117* Added intro message. 118* Removed stars without spectral class info from database. 119* Included support for cloud maps 120* Added extrasolar planets from the ESO's April 4th announcement 121* Axial rotation for stars 122* Alleviated clipping of very distant stars (Deneb was missing from Earth's 123 sky due to this bug.) 124* Increased depth buffer precision for planet rendering--this should improve 125 the quality of rendering with 16-bit z buffers 126* Added option to render constellation diagrams 127* Use strips instead of lists for rendering spheres 128* Enabled keyboard control of zoom with home and end 129* Implemented basics of linear scripting system 130* Run a script at startup; the script filename can be set in the config file 131 132Code revisions: 133* Converted Simulation class to use Julian days instead of seconds as internal 134 time units. 135* Eliminated brain damaged observer methods in Simulation 136* Cleaned up Console class 137 138 1391.07 140* More corrections to planetary orbital calculations 141* Accept LongOfPericenter as well ArgOfPericenter in solar system catalog files 142* Updated parser to accept C-style string escapes 143* Render the Milky Way and other galaxies 144* Added more constellations 145* Display constellation names 146* Cleaned up render menu 147* Added FPS counter 148* Implemented basic WWW info feature for planets and stars 149* New script commands: renderflags, labels, orbit 150* Implemented a scripted demo mode 151* Placed ISS in Earth orbit 152 153 1541.08 155* Initial UNIX port 156* Created GLUT based front-end 157* Created abstract Timer class with Windows and UNIX implementations 158 159 1601.09 161* UNIX port fixes: eliminated friend templates in Quaternion, added -lm to 162 configure.in, added missing return type for methods in Console and Overlay 163 164 1651.0.10 166* Fixed problem with ring shadow texture by setting wrap mode to GL_CLAMP_TO_EDGE 167* Corrected scale of ring shadow to match size of planet 168* Switched to octree based visibility determinination algorithm for 169 stars.

This allows for more sophisticated and fast treatment of massive catalogs. 874* Enabled very fast search of close-to-viewer deep sky objects. 875* Implemented brightness corrections involving the angle between 1-2 surface 876 normals and the viewing angle, such that the brightness distribution 877 gets ~ uniform for all galaxy orientations and Hubble types. This also 878 avoids excessive, unnatural brightness effects in edge-on views. 879* Galaxies get brighter with decreasing observer distance according to 880 realistic human eye sensitivity profile. 881* Brightness display optionally coupled with Automag scheme. 882* Enabled very fast picking of deep sky objects. 883* Placed galaxy templates in 'models/' directory. 884* Added various crucial fixes in galaxy.cpp, 885 - factor 2 was missing in the 'size' definition via the radius such that 886 distances among DSO's were grossly incorrect; 887 - fixed correct ordering of (non-commuting) operations in matrix m. 888 This gave incorrect galaxy orientations; 889 - To save space and to improve display: generate neat spherical E0 890 template from S0 disk template via rescaling by (1.0f, 3.8f, 1.0f); 891 - fixed wrong x,y alignment of elliptical rescaling. 892* Added code to ease compilation with newer Xcode versions (Macintosh). 893* Updated src/celengine/Makefile.am for Linux building. 894* Introduced a new cel function => renderflags {set "nebulae"}. 895* Reduced the default value of 'faintestAutoMag45deg' from 8.5 to 7.0. 896* Fixed the visibility of the Milky Way during day-time and the abrupt 897 appearance or disappearance of galaxies near the day-night border. 898* Enabled "geosynchronous Follow" (key 'Y') also for selected DSO's 899 (yet it does not seem to be very useful...). 900* Moved render flag check in the code such that labels can be drawn even if 901 e.g. renderGalaxy flag is turned off. 902* Suppressed apparent magnitude display for galaxy add-ons, lacking 903 specification of an absolute magnitude (absMag) input value. 904* Deleted various source code files that became superfluous. 905* Improved comet display. Introduced a neat scheme implementing comet tail 906 fading (between 4 and 6 AU for Sol). Systems with several suns and 907 luminosities different from the solar one are accounted for. 908* Implemented a new, simple scheme avoiding overcrowded galaxy labels. 909 Their "importance" is sorted according to apparent magnitude! Thus the 910 labels of the brightest galaxies pop up first upon zooming in... 911* Fixes/workarounds for OpenGL 2.0 render paths on both nVidia and ATI cards. 912 913 9141.4.1 915* Windows: Added time zone selection to set time dialog 916* Windows: Fixed hard to read text in set time dialog (bug was only present for 917 certain Windows shell appearance settings.) 918* Changed maximum number of eclipse shadows in OpenGL 2.0 path from two to 919 three; if max is exceeded, clamp to three rather than not rendering the 920 shadows at all. 921* Corrected a bad calculation in ring shadow shaders that caused ring shadows 922 to be drawn in the wrong place. 923* Windows: Fixed the minimum feature size slider in the locations dialog so it 924 updates in response to all the standard controls. 925* Added a correct InfoURL for the Moon 926* Windows: added splash screen with a progress indicator 927* KDE: fixed some AMD64 bugs 928* GTK: added splash screen with a progress indicator 929* GTK: Added configure options to enable or disable Cairo support for splash 930* Corrected a local flashing of the Milky Way brightness. 931* Now the distance to the galaxy center is displayed, if the observer is 932 located inside the galaxy (Milky Way...). 933* Eliminated various incorrect Hubble type acronyms in deepsky.dsc that had 934 penetrated the PERL filter. 935* Add the corrected PERL script deepsky.pl. 936* Mac: Universal binary - runs natively on Intel and PPC 937* Mac: OpenGL 2.0 render path should now work on many configurations 938 (requires OS X 10.4.3 or later) 939* Mac: Offer option to disable vertex programs automatically when ATI Radeon 940 9200 renderer is detected (avoids hard crash) 941* Mac: Progress message and version number displayed on splash screen 942* Mac: Couple of French translation fixes 943* Mac: Changed wording of "Subtract Light Travel Delay" menu item to 944 "Add/Subtract Light Travel Delay" to more accurately reflect its function 945* Mac: More sensible default values for preferences 946* Mac: Bug fixes to favorites, InfoURL handling 947* Mac: Full screen mode pauses when various panels are shown 948* Mac: Fixed crash when LANG or LC environment variables are set 949* Mac: Added bona fide English and French help menu 950* Mac: Cleaned up README in general 951* Added Phoebe textures in medres and lores directories from recent published 952 Ciclops cylindrical maps 953* Updated Titan and Iapetus textures in lores directory 954* Windows: save and restore the last used GL render path 955* Removed the GeForce FX render path;
