GNU GENERAL PUBLIC LICENSE

Version 2, June 1991
|
||||||
|
|
||||||
|
Copyright (C) 1989, 1991 Free Software Foundation, Inc.

|
||||||
|
Everyone is permitted to copy and distribute verbatim copies
|
||||||
|
of this license document, but changing it is not allowed.
|
||||||
|
|
||||||
|
Preamble
|
||||||
|
|
||||||
|
The licenses for most software are designed to take away your
|
||||||
|
freedom to share and change it. By contrast, the GNU General Public
|
||||||
|
License is intended to guarantee your freedom to share and change free
|
||||||
|
software--to make sure the software is free for all its users. This
|
||||||
|
General Public License applies to most of the Free Software
|
||||||
|
Foundation's software and to any other program whose authors commit to
|
||||||
|
using it. (Some other Free Software Foundation software is covered by
|
||||||
|
the GNU Library General Public License instead.) You can apply it to
|
||||||
|
your programs, too.
|
||||||
|
|
||||||
|
When we speak of free software, we are referring to freedom, not
|
||||||
|
price. Our General Public Licenses are designed to make sure that you
|
||||||
|
have the freedom to distribute copies of free software (and charge for
|
||||||
|
this service if you wish), that you receive source code or can get it
|
||||||
|
if you want it, that you can change the software or use pieces of it
|
||||||
|
in new free programs; and that you know you can do these things.
|
||||||
|
|
||||||
|
To protect your rights, we need to make restrictions that forbid
|
||||||
|
anyone to deny you these rights or to ask you to surrender the rights.
|
||||||
|
These restrictions translate to certain responsibilities for you if you
|
||||||
|
distribute copies of the software, or if you modify it.
|
||||||
|
|
||||||
|
For example, if you distribute copies of such a program, whether
|
||||||
|
gratis or for a fee, you must give the recipients all the rights that
|
||||||
|
you have. You must make sure that they, too, receive or can get the
|
||||||
|
source code. And you must show them these terms so they know their
|
||||||
|
rights.
|
||||||
|
|
||||||
|
We protect your rights with two steps: (1) copyright the software, and
|
||||||
|
(2) offer you this license which gives you legal permission to copy,
|
||||||
|
distribute and/or modify the software.
|
||||||
|
|
||||||
|
Also, for each author's protection and ours, we want to make certain
|
||||||
|
that everyone understands that there is no warranty for this free
|
||||||
|
software. If the software is modified by someone else and passed on, we
|
||||||
|
want its recipients to know that what they have is not the original, so
|
||||||
|
that any problems introduced by others will not reflect on the original
|
||||||
|
authors' reputations.
|
||||||
|
|
||||||
|
Finally, any free program is threatened constantly by software
|
||||||
|
patents. We wish to avoid the danger that redistributors of a free
|
||||||
|
program will individually obtain patent licenses, in effect making the
|
||||||
|
program proprietary. To prevent this, we have made it clear that any
|
||||||
|
patent must be licensed for everyone's free use or not licensed at all.
|
||||||
|
|
||||||
|
The precise terms and conditions for copying, distribution and
|
||||||
|
modification follow.
|
||||||
|
|
||||||
|
GNU GENERAL PUBLIC LICENSE
|
||||||
|
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||||
|
|
||||||
|
0. This License applies to any program or other work which contains
|
||||||
|
a notice placed by the copyright holder saying it may be distributed
|
||||||
|
under the terms of this General Public License. The "Program", below,
|
||||||
|
refers to any such program or work, and a "work based on the Program"
|
||||||
|
means either the Program or any derivative work under copyright law:
|
||||||
|
that is to say, a work containing the Program or a portion of it,
|
||||||
|
either verbatim or with modifications and/or translated into another
|
||||||
|
language. (Hereinafter, translation is included without limitation in
|
||||||
|
the term "modification".) Each licensee is addressed as "you".
|
||||||
|
|
||||||
|
Activities other than copying, distribution and modification are not
|
||||||
|
covered by this License; they are outside its scope. The act of
|
||||||
|
running the Program is not restricted, and the output from the Program
|
||||||
|
is covered only if its contents constitute a work based on the
|
||||||
|
Program (independent of having been made by running the Program).
|
||||||
|
Whether that is true depends on what the Program does.
|
||||||
|
|
||||||
|
1. You may copy and distribute verbatim copies of the Program's
|
||||||
|
source code as you receive it, in any medium, provided that you
|
||||||
|
conspicuously and appropriately publish on each copy an appropriate
|
||||||
|
copyright notice and disclaimer of warranty; keep intact all the
|
||||||
|
notices that refer to this License and to the absence of any warranty;
|
||||||
|
and give any other recipients of the Program a copy of this License
|
||||||
|
along with the Program.
|
||||||
|
|
||||||
|
You may charge a fee for the physical act of transferring a copy, and
|
||||||
|
you may at your option offer warranty protection in exchange for a fee.
|
||||||
|
|
||||||
|
2. You may modify your copy or copies of the Program or any portion
|
||||||
|
of it, thus forming a work based on the Program, and copy and
|
||||||
|
distribute such modifications or work under the terms of Section 1
|
||||||
|
above, provided that you also meet all of these conditions:
|
||||||
|
|
||||||
|
a) You must cause the modified files to carry prominent notices
|
||||||
|
stating that you changed the files and the date of any change.
|
||||||
|
|
||||||
|
b) You must cause any work that you distribute or publish, that in
|
||||||
|
whole or in part contains or is derived from the Program or any
|
||||||
|
part thereof, to be licensed as a whole at no charge to all third
|
||||||
|
parties under the terms of this License.
|
||||||
|
|
||||||
|
c) If the modified program normally reads commands interactively
|
||||||
|
when run, you must cause it, when started running for such
|
||||||
|
interactive use in the most ordinary way, to print or display an
|
||||||
|
announcement including an appropriate copyright notice and a
|
||||||
|
notice that there is no warranty (or else, saying that you provide
|
||||||
|
a warranty) and that users may redistribute the program under
|
||||||
|
these conditions, and telling the user how to view a copy of this
|
||||||
|
License. (Exception: if the Program itself is interactive but
|
||||||
|
does not normally print such an announcement, your work based on
|
||||||
|
the Program is not required to print an announcement.)
|
||||||
|
|
||||||
|
These requirements apply to the modified work as a whole. If
|
||||||
|
identifiable sections of that work are not derived from the Program,
|
||||||
|
and can be reasonably considered independent and separate works in
|
||||||
|
themselves, then this License, and its terms, do not apply to those
|
||||||
|
sections when you distribute them as separate works. But when you
|
||||||
|
distribute the same sections as part of a whole which is a work based
|
||||||
|
on the Program, the distribution of the whole must be on the terms of
|
||||||
|
this License, whose permissions for other licensees extend to the
|
||||||
|
entire whole, and thus to each and every part regardless of who wrote it.
|
||||||
|
|
||||||
|
Thus, it is not the intent of this section to claim rights or contest
|
||||||
|
your rights to work written entirely by you; rather, the intent is to
|
||||||
|
exercise the right to control the distribution of derivative or
|
||||||
|
collective works based on the Program.
|
||||||
|
|
||||||
|
In addition, mere aggregation of another work not based on the Program
|
||||||
|
with the Program (or with a work based on the Program) on a volume of
|
||||||
|
a storage or distribution medium does not bring the other work under
|
||||||
|
the scope of this License.
|
||||||
|
|
||||||
|
3. You may copy and distribute the Program (or a work based on it,
|
||||||
|
under Section 2) in object code or executable form under the terms of
|
||||||
|
Sections 1 and 2 above provided that you also do one of the following:
|
||||||
|
|
||||||
|
a) Accompany it with the complete corresponding machine-readable
|
||||||
|
source code, which must be distributed under the terms of Sections
|
||||||
|
1 and 2 above on a medium customarily used for software interchange; or,
|
||||||
|
|
||||||
|
b) Accompany it with a written offer, valid for at least three
|
||||||
|
years, to give any third party, for a charge no more than your
|
||||||
|
cost of physically performing source distribution, a complete
|
||||||
|
machine-readable copy of the corresponding source code, to be
|
||||||
|
distributed under the terms of Sections 1 and 2 above on a medium
|
||||||
|
customarily used for software interchange; or,
|
||||||
|
|
||||||
|
c) Accompany it with the information you received as to the offer
|
||||||
|
to distribute corresponding source code. (This alternative is
|
||||||
|
allowed only for noncommercial distribution and only if you
|
||||||
|
received the program in object code or executable form with such
|
||||||
|
an offer, in accord with Subsection b above.)
|
||||||
|
|
||||||
|
The source code for a work means the preferred form of the work for
|
||||||
|
making modifications to it. For an executable work, complete source
|
||||||
|
code means all the source code for all modules it contains, plus any
|
||||||
|
associated interface definition files, plus the scripts used to
|
||||||
|
control compilation and installation of the executable. However, as a
|
||||||
|
special exception, the source code distributed need not include
|
||||||
|
anything that is normally distributed (in either source or binary
|
||||||
|
form) with the major components (compiler, kernel, and so on) of the
|
||||||
|
operating system on which the executable runs, unless that component
|
||||||
|
itself accompanies the executable.
|
||||||
|
|
||||||
|
If distribution of executable or object code is made by offering
|
||||||
|
access to copy from a designated place, then offering equivalent
|
||||||
|
access to copy the source code from the same place counts as
|
||||||
|
distribution of the source code, even though third parties are not
|
||||||
|
compelled to copy the source along with the object code.
|
||||||
|
|
||||||
|
4. You may not copy, modify, sublicense, or distribute the Program
|
||||||
|
except as expressly provided under this License. Any attempt
|
||||||
|
otherwise to copy, modify, sublicense or distribute the Program is
|
||||||
|
void, and will automatically terminate your rights under this License.
|
||||||
|
However, parties who have received copies, or rights, from you under
|
||||||
|
this License will not have their licenses terminated so long as such
|
||||||
|
parties remain in full compliance.
|
||||||
|
|
||||||
|
5. You are not required to accept this License, since you have not
|
||||||
|
signed it. However, nothing else grants you permission to modify or
|
||||||
|
distribute the Program or its derivative works. These actions are
|
||||||
|
prohibited by law if you do not accept this License. Therefore, by
|
||||||
|
modifying or distributing the Program (or any work based on the
|
||||||
|
Program), you indicate your acceptance of this License to do so, and
|
||||||
|
all its terms and conditions for copying, distributing or modifying
|
||||||
|
the Program or works based on it.
|
||||||
|
|
||||||
|
6. Each time you redistribute the Program (or any work based on the
|
||||||
|
Program), the recipient automatically receives a license from the
|
||||||
|
original licensor to copy, distribute or modify the Program subject to
|
||||||
|
these terms and conditions. You may not impose any further
|
||||||
|
restrictions on the recipients' exercise of the rights granted herein.
|
||||||
|
You are not responsible for enforcing compliance by third parties to
|
||||||
|
this License.
|
||||||
|
|
||||||
|
7. If, as a consequence of a court judgment or allegation of patent
|
||||||
|
infringement or for any other reason (not limited to patent issues),
|
||||||
|
conditions are imposed on you (whether by court order, agreement or
|
||||||
|
otherwise) that contradict the conditions of this License, they do not
|
||||||
|
excuse you from the conditions of this License. If you cannot
|
||||||
|
distribute so as to satisfy simultaneously your obligations under this
|
||||||
|
License and any other pertinent obligations, then as a consequence you
|
||||||
|
may not distribute the Program at all. For example, if a patent
|
||||||
|
license would not permit royalty-free redistribution of the Program by
|
||||||
|
all those who receive copies directly or indirectly through you, then
|
||||||
|
the only way you could satisfy both it and this License would be to
|
||||||
|
refrain entirely from distribution of the Program.
|
||||||
|
|
||||||
|
If any portion of this section is held invalid or unenforceable under
|
||||||
|
any particular circumstance, the balance of the section is intended to
|
||||||
|
apply and the section as a whole is intended to apply in other
|
||||||
|
circumstances.
|
||||||
|
|
||||||
|
It is not the purpose of this section to induce you to infringe any
|
||||||
|
patents or other property right claims or to contest validity of any
|
||||||
|
such claims; this section has the sole purpose of protecting the
|
||||||
|
integrity of the free software distribution system, which is
|
||||||
|
implemented by public license practices. Many people have made
|
||||||
|
generous contributions to the wide range of software distributed
|
||||||
|
through that system in reliance on consistent application of that
|
||||||
|
system; it is up to the author/donor to decide if he or she is willing
|
||||||
|
to distribute software through any other system and a licensee cannot
|
||||||
|
impose that choice.
|
||||||
|
|
||||||
|
This section is intended to make thoroughly clear what is believed to
|
||||||
|
be a consequence of the rest of this License.
|
||||||
|
|
||||||
|
8. If the distribution and/or use of the Program is restricted in
|
||||||
|
certain countries either by patents or by copyrighted interfaces, the
|
||||||
|
original copyright holder who places the Program under this License
|
||||||
|
may add an explicit geographical distribution limitation excluding
|
||||||
|
those countries, so that distribution is permitted only in or among
|
||||||
|
countries not thus excluded. In such case, this License incorporates
|
||||||
|
the limitation as if written in the body of this License.
|
||||||
|
|
||||||
|
9. The Free Software Foundation may publish revised and/or new versions
|
||||||
|
of the General Public License from time to time. Such new versions will
|
||||||
|
be similar in spirit to the present version, but may differ in detail to
|
||||||
|
address new problems or concerns.
|
||||||
|
|
||||||
|
Each version is given a distinguishing version number. If the Program
|
||||||
|
specifies a version number of this License which applies to it and "any
|
||||||
|
later version", you have the option of following the terms and conditions
|
||||||
|
either of that version or of any later version published by the Free
|
||||||
|
Software Foundation. If the Program does not specify a version number of
|
||||||
|
this License, you may choose any version ever published by the Free Software
|
||||||
|
Foundation.
|
||||||
|
|
||||||
|
10. If you wish to incorporate parts of the Program into other free
|
||||||
|
programs whose distribution conditions are different, write to the author
|
||||||
|
to ask for permission. For software which is copyrighted by the Free
|
||||||
|
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||||
|
make exceptions for this. Our decision will be guided by the two goals
|
||||||
|
of preserving the free status of all derivatives of our free software and
|
||||||
|
of promoting the sharing and reuse of software generally.
|
||||||
|
|
||||||
|
NO WARRANTY
|
||||||
|
|
||||||
|
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||||
|
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||||
|
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||||
|
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||||
|
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||||
|
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||||
|
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||||
|
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||||
|
REPAIR OR CORRECTION.
|
||||||
|
|
||||||
|
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||||
|
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||||
|
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||||
|
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||||
|
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||||
|
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||||
|
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||||
|
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||||
|
POSSIBILITY OF SUCH DAMAGES.

|
||||||
|
|
||||||
|
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

|
||||||
|
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.
|
||||||
|

|
||||||
|
* 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

|
||||||
|
on a per texture basis in .ssc files.
|
||||||
|
* Added a reverse time option
|
||||||
|
* Added an OpenGL Driver Info item to the help menu
|
||||||

|
||||||
|
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
|
||||||
|

|
||||||
|
* Fixed orbital calculations for planets so their positions are now closer to
|
||||||

|
* 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.

|
||||||
|
* 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
|
||||||
|

||||||
|
Getting started:
|
||||||
|
|
||||||
|
Important: Celestia must be started from the directory in which the EXE
|
||||||
|
resides or else it will not find its data files. A real installer is
|
||||||
|
forthcoming.
|
||||||
|
|
||||||
|
Celestia will start up in a window, and if everything is working
|
||||||
|
correctly, you'll see the asteroid Eros moving past a field of
|
||||||
|
stars. In the left corner is a welcome message and some information
|
||||||
|
about your target (Eros), your speed, and the current time (Universal
|
||||||
|
Time, so it'll probably be a few hours off from your computer's clock.)
|
||||||
|
Right drag the mouse to orbit Eros and you should see the Earth and some
|
||||||
|
familiar constellations. Left dragging the mouse changes your
|
||||||
|
orientation too, but the camera rotates about its center instead of
|
||||||
|
rotating around Eros. Rolling the mouse wheel will change your distance
|
||||||
|
to the space station--you can move light years away, then roll the wheel
|
||||||
|
in the opposite direction to get back to your starting location. If your
|
||||||
|
mouse lacks a wheel, you can use the Home and End keys instead.
|
||||||
|
|
||||||
|
In Celestia, you'll generally have an object selected; currently,
|
||||||
|
it's Eros, but it could also be a star, planet, spacecraft, or galaxy.
|
||||||
|
The simplest way to select an object is to click on it. Try clicking
|
||||||
|
on a star to select it. The information about Eros is replaced with
|
||||||
|
some details about the star. Press G (or use the navigation menu),
|
||||||
|
and you'll zoom through space toward the selected star. If you
|
||||||
|
press G again, you'll approach the star even closer.
|
||||||
|
|
||||||
|
Press H to select our Sun, and then G to go back to our solar system.
|
||||||
|
You'll find yourself half a light year away from the sun, which looks
|
||||||
|
merely like a bright star at this range. Press G three more times to
|
||||||
|
get within about 30 AU of the sun and you will be to see a few become
|
||||||
|
visible near the sun. Right click on the sun to bring up a menu of
|
||||||
|
planets and other objects in the solar system. After selecting a planet
|
||||||
|
from the menu, hit G again to travel toward it. Once there, hold down
|
||||||
|
the right mouse button and drag to orbit the planet.
|
||||||
|
|
||||||
|
That covers the very basics . . .
|
||||||
|
|
||||||
|
|
||||||
|
MOUSE FUNCTIONS:
|
||||||
|
|
||||||
|
Left drag to orient camera
|
||||||
|
Right drag to orbit the selected object
|
||||||
|
Use the mouse wheel to adjust distance to selection
|
||||||
|
(for wheelless mice, dragging while holding left and right
|
||||||
|
buttons or left dragfing while holding control to dolly camera
|
||||||
|
will adjust distance)
|
||||||
|
Left drag while holding shift to zoom
|
||||||
|
Click the wheel to reset the field of view to 45 degrees
|
||||||
|
Left-click to select; double click to center selection
|
||||||
|
Right-click to bring up planets menu
|
||||||
|
|
||||||
|

||||||
|
|
||||||
|
It's possible to choose a star or planet by name. There are two ways to
|
||||||
|
enter a star name: choose 'Select Object' from the Navigation menu to
|
||||||
|
bring up a dialog box, or by hitting Enter, typing in the name, and
|
||||||
|
pressing Enter again. You can use common names, or Bayer designations
|
||||||
|
and HD catalog numbers for stars. Bayer and Flamsteed designations need
|
||||||
|
to be entered like this:
|
||||||
|
Upsilon And
|
||||||
|
51 Peg
|
||||||
|
The constellation must be given as a three letter abbreviation and the
|
||||||
|
full Greek letter name spelled out. Irritating, but it'll be fixed.
|
||||||
|
HD catalog numbers must be entered with a space between HD and the number.
|
||||||
|
|
||||||
|
Celestia handles star catalog numbers in a slightly kludgy way. To keep the
|
||||||
|
star database size to minimum, only one catalog number is stored. Normally,
|
||||||
|
this will a number from the HD catalog, but if a star isn't in the HD catalog
|
||||||
|
the number from another catalog will be used instead. Currently, the secondary
|
||||||
|
catalog is always the HIPPARCOS data set, for which the prefix "HIP" should be
|
||||||
|
used.
|
||||||
|
|
||||||
|
|
||||||
|
Basic Hacking Tips:
|
||||||
|
|
||||||
|
It's possible to modify the solarsys.ssc, stars.dat, and hdnames.dat
|
||||||
|
files to create an entirely fictional universe.
|
||||||
|
|
||||||
|
The easiest file to modify is the solar system catalog, as it's a text
|
||||||
|
file and the format is very text-editor friendly since that's how I
|
||||||
|
had to enter all the data. It's also quite verbose, but that's not a
|
||||||
|
problem yet.
|
||||||
|
|
||||||
|
The units used for the solar system data may not be obvious. All
|
||||||
|
angle fields in the catalog are in degrees. For planets, the period
|
||||||
|
is specified in earth years, and the semi-major axis in AU; for
|
||||||
|
satellites, days and kilometers are used instead.
|
||||||
|
|
||||||
|
All solar system textures should be placed in the textures
|
||||||
|
subdirectory. Currently, JPEG and BMP are the only formats supported.
|
||||||
|
Models belong in the models directory. Celestia can read 3DS models,
|
||||||
|
as well as a custom format (.cms files, used right now just for rough
|
||||||
|
fractal displacement map likenesses of asteroids and small moons.) 3DS
|
||||||
|
meshes are normalized to fit within a unit cube--the Radius field
|
||||||
|
determines how big they appear within Celestia.
|
||||||
|
|
||||||
|
The stars.dat file is a binary database of stars, processed from
|
||||||
|
the 50+ meg HIPPARCOS data set. The first four bytes are an int
|
||||||
|
containing the number of stars in the database. Following that
|
||||||
|
are a bunch of records of this form:
|
||||||
|
|
||||||
|
4 byte int : catalog number
|
||||||
|
4 byte float : right ascension
|
||||||
|
4 byte float : declination
|
||||||
|
4 byte float : parallax
|
||||||
|
2 byte int : apparent magnitude
|
||||||
|
2 byte int : stellar class
|
||||||
|
1 byte : parallax error
|
||||||
|
|
||||||
|
RA, declination, and parallax are converted to x, y, z coordinates
|
||||||
|
and apparent magnitude is converted to absolute magnitude when the
|
||||||
|
database is read.
