Short: Images of sky from any planet or comet. Author: pete@lpad.demon.co.uk (Peter Knight) Uploader: pete lpad demon co uk (Peter Knight) Type: misc/sci Version: 3.0 Replaces: misc/sci/VWorld* Architecture: m68k-amigaos Description ----------- This is VWorlds v3.0 (26/10/96), an update to v2.1 with many new features (e.g. artificial earth satellite positions, more planetary moons, space probe trajectories and more!) 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 Orrery, showing positions and orbits of planets and comets from any point with respect to the Sun. o Customizable comet and artificial satellite databases. The position of all the objects entered into the database is calculated and their position displayed. o Plotting of all stars down to magnitude 8.0 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, lunar occultation etc. 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 8 Mb free RAM (1 Mb chip / 7 Mb fast). o WB 3.0 (or better). o 68020 (or better). o Hard disk drive with at least 5 Mb free space. Recommended ----------- o Floating point unit. o Multiscan monitor.
