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.
