Choose a point within about 1000 light years of Earth, and Celestia +will show you an approximation of how it would appear to your eyes were you +actually there. Some of what Celestia shows is necessarily hypothetical--the +farther away from Earth you get, the less real data there is and the more +guesswork is involved. Thus Celestia supplements observational data with good +guesses based on models of stellar and planetary processes. +.PP +Celestia is unique in its ability to allow you to navigate at an immense range +of scales. Orbit a couple kilometers above the surface of a tiny, irregular +asteroid, then head off toward Jupiter, watching it grow from a bright point of +light into a looming sphere filling your field of vision. Leave our solar +system entirely and observe the sun as it fades from a brilliant disk to a +bright star, disappearing almost entirely as you head off toward the Upsilon +Andromeda system to orbit around its innermost giant planet. +.SH OVERVIEW +Celestia will start up in a window, display a welcome message and some +information about your target (top left corner), your speed, and the +current time (Universal Time, so it'll probably be a few hours off from +your computer's clock.) 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. Right drag the mouse to +orbit arround the selected target. Left dragging the mouse changes your +orientation too, but the camera rotates about its center instead of +rotating around the target. 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. +.PP +Press G 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 planets 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. +.SH USAGE +Mouse functions: +.PP +.TS +tab (@); +l l. +Left drag@orient camera +Right drag@orbit the selected object +Mouse wheel,@ +Middle drag@adjust distance to selection +left click@select target, double click to center +.TE +.PP +Keyboard commands: +.PP +Navigation +.PP +.TS +tab (@); +l l. +H@Select the sun (Home) +C@Center on selected object +G@Goto selected object +F@Follow selected object +Y@Orbit the selected object at a rate synced to its rotation +ESC@Cancel motion +.TE +.PP +Free movement +.PP +.TS +tab (@); +l l. +HOME@Move closer to object +END@Move farther from object +F1@Stop +F2@Set velocity to 1 km/s +F3@Set velocity to 1,000 km/s +F4@Set velocity to 1,000,000 km/s +F5@Set velocity to 1 AU/s +F6@Set velocity to 1 ly/s +A@Increase velocity by 10x +Z@Decrease velocity by 10x +Q@Reverse direction +X@Set movement direction toward center of screen +.TE +.PP +Time +.PP +.TS +tab (@); +l l. +Space@stop time +L@Time 10x faster +K@Time 10x slower +J@Reverse time +.TE +.PP +Options +.PP +.TS +tab (@); +l l. +U@Toggle galaxy rendering +N@Toggle planet and moon labels +O@Toggle planet orbits +V@Toggle HUD Text +I@Toggle planet atmospheres (cloud textures) +W@Toggle wireframe mode +/@Toggle constellation diagrams += @Toggle constellation labels +;@Toggle earth-based equatorial coordinate sphere +B@Toggle star labels +P@Toggle per-pixel lighting (if supported) +[@Decrease limiting magnitude (fewer stars visible) +]@Increase limiting magnitude (more stars visible) +{@Decrease ambient illumination +}@Increase ambient illumination +,@Narrow field of view +\.@Widen field of view +.TE +.PP +Other +.PP +.TS +tab (@); +l l. +D@Run demo +`@Show frames rendered per second +.TE +.PP +It's possible to choose a star or planet by name: press Enter and type 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 "Upsilon And" and "51 Peg". The +constellation must be given as a three letter abbreviation and the full Greek +letter name spelled out. HD catalog numbers must be entered with a space +between HD and the number. +.SH OPTIONS +The \fIglut\fP based version accepts the usual X Window System specific +options, namely: +.TP 8 +.B \-display \fIDISPLAY\fP +Specify the X server to connect to. If not specified, the value of the +DISPLAY environment variable is used. +.TP 8 +.B \-geometry \fIWxH+X+Y\fP +Determines where window's should be created on the screen. The +parameter following -geometry should be formatted as a +standard X geometry specification. The effect of using this option +is to change the GLUT initial size and initial position the same as +if glutInitWindowSize or glutInitWindowPosition were +called directly. +.TP 8 +.B \-iconic +Requests all top-level windows be created in an iconic state. +.TP 8 +.B \-indirect +Force the use of indirect OpenGL rendering contexts. +.TP 8 +.B \-direct +Force the use of direct OpenGL rendering contexts (not all GLX +implementations support direct rendering contexts). A fatal error +is generated if direct rendering is not supported by the OpenGL +implementation. + +If neither -indirect or -direct are used to force a particular +behavior, GLUT will attempt to use direct rendering if possible +and otherwise fallback to indirect rendering. +.TP 8 +.B \-gldebug +After processing callbacks and/or events, check if there are any +OpenGL errors by calling glGetError. If an error is reported, +print out a warning by looking up the error code with +gluErrorString. Using this option is helpful in detecting +OpenGL run-time errors. +.TP 8 +.B \-sync +Enable synchronous X protocol transactions. This option makes it +easier to track down potential X protocol errors. +.SH AUTHOR +Celestia has been written by Chris Laurel <claurel@www.shatters.net> and +it's available under the terms and conditions of the GNU General Public +License from http://celestia.sf.net/ |
