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
