Short: Images of sky from any planet or comet. Author: pak@star.sr.bham.ac.uk (Peter Knight) Uploader: pak@star.sr.bham.ac.uk (Peter Knight) Version: 2.1 Type: misc/sci Replaces: misc/sci/VWorld* Description ----------- This is VWorlds v2.1 (28/4/96), an update to v2.0 with the addition of a planetarium mode showing objects above the horizon, and several other significant improvements. Main features ------------- o Accurate numerical ephemeris giving planetary/lunar/solar positions to an accuracy of a few seconds of arc. o Realistic rendering of all major solar system bodies (Sun, Moon, planets, selected comets & satellites). The solar system can be viewed from a point on any of these objects, not just the Earth. o Texture-mapped images of the Earth, Moon and Mars when viewed from another body, with shading of night/twilight zones. o Scalable projected map of the world showing shaded night/twilight zones, position of observer and location of Moon's umbra and penumbra during solar eclipses. o Maps of Moon and Mars showing longitude of central meridian. o Orrery, showing positions and orbits of planets and comets from any point with respect to the Sun. o Customizable comet database. The position of all the comets entered into the database is calculated and their position displayed (includes comets Hyakutake and Hale-Bopp). o Plotting of all stars down to magnitude 7.0 from the SAO catalogue, with proper motion information. o Accurate prediction of 'special events'---solar/lunar eclipse, full/new moon, Mercury/Venus conjunction, Mars opposition and lunar occultation. o Shading of Milky Way region. o Constellation outlines and names. o Overlaid annotated grids (horizon, equatorial and ecliptic coordinate systems). o Selectable viewport orientation (horizon, equatorial or ecliptic systems). o Shading of sky region below horizon. o Continuous update and accelerated time modes for animations. o Easy to use GadTools interface. o It's Public Domain. You get a fully-functioning program! Requires an Amiga computer with... ---------------------------------- o 256 colour intuition screen (some gfx cards may work, but there are known problems with CyberGfx). o at least 3.5 Mb free RAM (1 Mb chip / 2.5 Mb fast). o WB 3.0 (or better). o 68020 (or better). o Hard disk drive with at least 2 Mb free space. Recommended ----------- o Floating point unit. o Multiscan monitor. ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 1922 946 50.7% 11-May-96 19:34:44 VWorlds21.info 556 351 36.8% 11-May-96 19:25:20 +comet.dat 103568 84783 18.1% 11-May-96 19:25:26 +earth.map 1922 942 50.9% 12-May-96 14:32:00 +Extras.info 93310 66331 28.9% 11-May-96 19:29:00 +earth.map 612 362 40.8% 11-May-96 19:29:06 +ReadMe.doc 835 276 66.9% 12-May-96 14:32:00 +ReadMe.doc.info 7964 3015 62.1% 12-May-96 14:32:00 +VWorlds.info 1528 699 54.2% 12-May-96 14:32:00 +VWorlds2.info 2480 955 61.4% 11-May-96 19:25:32 +Install 756 382 49.4% 11-May-96 19:30:52 +Install.info 95892 68980 28.0% 11-May-96 19:25:42 +map.dat 127018 118705 6.5% 11-May-96 19:25:48 +mars.map 2834 2728 3.7% 11-May-96 19:25:54 +messier.dat 100754 87453 13.2% 11-May-96 19:26:00 +moon.map 2934 2934 0.0% 11-May-96 19:26:04 +mw.dat 15552 15149 2.5% 11-May-96 19:26:08 +orrery.dat 2473 1254 49.2% 12-May-96 17:05:30 +ReadMe.doc 835 279 66.5% 11-May-96 19:30:52 +ReadMe.doc.info 3288 2027 38.3% 11-May-96 19:26:26 +shape.dat 539410 483990 10.2% 11-May-96 19:26:32 +stars.dat 307640 132722 56.8% 12-May-96 17:05:48 +VWorlds 298 243 18.4% 12-May-96 17:12:00 +VWorlds.config 32947 12219 62.9% 12-May-96 18:13:06 +VWorlds.guide 840 281 66.5% 11-May-96 19:30:52 +VWorlds.guide.info 1836 700 61.8% 11-May-96 19:30:52 +VWorlds.info 232284 109965 52.6% 12-May-96 17:05:40 +VWorlds_881 1837 699 61.9% 11-May-96 19:30:52 +VWorlds_881.info -------- ------- ----- --------- -------- 1684125 1199370 28.7% 18-May-96 19:46:00 28 files
