Celestia Revision History
|
|
-------------------------
|
|
|
|
1.00
|
|
* Initial public release
|
|
|
|
|
|
1.01
|
|
* Added more realistic and aesthetically pleasing ring illumination function
|
|
* Made planets project shadows onto their rings (requires multitexturing)
|
|
* Detect and use ARB_multitexture extension
|
|
* Some configuration parameters now read from a file
|
|
* Support for multiple solar system catalog files
|
|
* Split solar system files into solarsys.ssc and extrasolar.ssc
|
|
* Added Help/License menu
|
|
* Added simple camera orbit mode
|
|
* Fixed up parsing and printing of catalog numbers--still kludgy though
|
|
|
|
|
|
1.02
|
|
* Made Celestia icon appear in corner of window. Whee.
|
|
* Fixed an extremely subtle numerical precision bug which manifested itself in
|
|
a number of ways: jittering when following small objects, incorrect
|
|
targeting of small objects with goto, occasional flashes when closely
|
|
approaching an object, and probably other things as well.
|
|
* Reversed rotation directions when orbiting--it's much more intuitive now
|
|
* Added an exponential dolly capability to the camera
|
|
* Double-clicking will now center on the selected object
|
|
* Fixed bug in elliptical orbit calculation
|
|
* When orbits are displayed, the Orbit for the selected object is highlighted
|
|
* Incorporated Scott Hudson's asteroid geometry data for Toutatis, Kleopatra,
|
|
and Geographos.
|
|
* Fixed problems with disappearing labels and with misplaced labels for
|
|
extrasolar planets
|
|
* Eliminated 'sticking' when mouse buttons released outside of Celestia window
|
|
* Added Real Time option to Time menu
|
|
* Reversed planet rotation direction so it's correct. Oops.
|
|
* Added about a dozen extrasolar systems from Jean Schneider's catalog
|
|
* Create two new textures for extrasolar planets
|
|
* Moved Selection class outside of Simulation, as it's generally useful
|
|
|
|
|
|
1.03
|
|
* Rotating the camera is now more responsive to mouse movement
|
|
* 'Infinite mouse' hack allows rotating and dollying without having to pick up
|
|
the mouse and reposition the cursor in the window
|
|
* Fixed z ordering for planets and satellites so small that they only appear
|
|
as points. Small satellites will no longer get obscured by planets they're
|
|
in front of.
|
|
* Apparent magnitude calculation for planets now takes into account phase
|
|
* At close range, stars are now rendered as textured sphere meshes.
|
|
* Choosing stars by catalog number no longer selects a star even when the specified
|
|
star doesn't exist.
|
|
* Added labels for stars; the list of labelled stars is read from celestia.cfg
|
|
* Cleaned up vecmath.h, added consts and reference parameters where appropriate
|
|
* Cleaned up StarNameDatabase
|
|
|
|
|
|
1.04
|
|
* Start out at the moon instead of in deep space
|
|
* Made picking of planets work properly for planets with disc sizes greater than one
|
|
pixel.
|
|
* Added call to glDeleteTextures to Texture class destructor
|
|
* Added bump mapping. Uses DOT3 bump mapping and only works on GeForce cards
|
|
right now.
|
|
* Enabled user control of per-pixel lighting.
|
|
* Menu checked state for label options synced with renderer state.
|
|
* Added a context menu that appears when an object is right clicked.
|
|
* Celestia now uses texture coordinates from 3DS files
|
|
* Added 3DS model of Eros based on NEAR laser rangefinder data
|
|
* Added 3DS models of Deimos, Phobos, and numerous other asteroids and
|
|
small moons based on Phil Stooke's models
|
|
* Replaced TriangleList class with much more flexible VertexList
|
|
* Introduced support for compressed textures; texture compression is specified
|
|
on a per texture basis in .ssc files.
|
|
* Added a reverse time option
|
|
* Added an OpenGL Driver Info item to the help menu
|
|
|
|
|
|
1.05
|
|
* Made per-pixel lighting work for planets without bump maps too
|
|
* Allow user control of magnitude of faintest visible stars
|
|
* Added support for PNG textures
|
|
* Improved console: enabled backspace, relocated text entry, code cleanup, ...
|
|
* Corrected star positions by converting them from equatorial to ecliptical
|
|
coordinates.
|
|
* Eliminated case sensitivity when selecting objects by name
|
|
* New ring texture for Saturn with separate reflectance and opacity
|
|
* Ring textures now specified in .ssc files instead of hardcoded
|
|
* Implemented date/time selector dialog box
|
|
* Changed the mouse wheel function from zoom to dolly. Zoom is now controlled by
|
|
shift left-dragging the mouse. For mice without wheels, control left-dragging
|
|
will dolly.
|
|
* Fixed orbit and dolly functions to work in follow mode
|
|
* Improved rendering of objects at close range: less clipping, extra sphere LOD.
|
|
* Fixed bug that caused irregular objects to be displayed at half their actual size
|
|
* ESC now cancels goto and follow instead of exiting app.
|
|
* Fixed orbital calculations for planets so their positions are now closer to
|
|
reality.
|
|
* Completed extrasolar planets database; it now contains all known planets
|
|
around normal stars
|
|
* Mir!
|
|
* MeanAnomaly field in .ssc files was incorrectly called TrueAnomaly; this
|
|
is fixed, and solar system parser now also accepts MeanLongitude in orbital
|
|
elements section.
|
|
* Epoch can now be specified for orbital elements. Default is J2000.
|
|
|
|
|
|
1.06
|
|
* Made Alt+F4 exit the app.
|
|
* Fixed text rendering to be pixel-accurate; labels and console text are now
|
|
crisper and don't have any missing pixels (need to test on more graphics
|
|
chipsets.)
|
|
* Updated parser to handle negative numbers. Big oops.
|
|
* Corrected errors and omissions in extrasolar planets catalog.
|
|
* Added locations menu for saving and recalling favorite places.
|
|
* Added intro message.
|
|
* Removed stars without spectral class info from database.
|
|
* Included support for cloud maps
|
|
* Added extrasolar planets from the ESO's April 4th announcement
|
|
* Axial rotation for stars
|
|
* Alleviated clipping of very distant stars (Deneb was missing from Earth's
|
|
sky due to this bug.)
|
|
* Increased depth buffer precision for planet rendering--this should improve
|
|
the quality of rendering with 16-bit z buffers
|
|
* Added option to render constellation diagrams
|
|
* Use strips instead of lists for rendering spheres
|
|
* Enabled keyboard control of zoom with home and end
|
|
* Implemented basics of linear scripting system
|
|
* Run a script at startup; the script filename can be set in the config file
|
|
|
|
Code revisions:
|
|
* Converted Simulation class to use Julian days instead of seconds as internal
|
|
time units.
|
|
* Eliminated brain damaged observer methods in Simulation
|
|
* Cleaned up Console class
|
|
|
|
|
|

|
|
* More corrections to planetary orbital calculations
|
|
* Accept LongOfPericenter as well ArgOfPericenter in solar system catalog files
|
|
* Updated parser to accept C-style string escapes
|
|
* Render the Milky Way and other galaxies
|
|
* Added more constellations
|
|
* Display constellation names
|
|
* Cleaned up render menu
|
|
* Added FPS counter
|
|
* Implemented basic WWW info feature for planets and stars
|

* New script commands: renderflags, labels, orbit
|
|
* Implemented a scripted demo mode
|
|
* Placed ISS in Earth orbit
