Short: Images of sky from any planet or comet. Uploader: pak@star.sr.bham.ac.uk (Peter Knight) Author: pak@star.sr.bham.ac.uk (Peter Knight) Type: misc/sci Version: 2.1 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.
