- 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.
