General
-
- The primary role of special-effects projectors in the modern
planetarium is that of creating an environment. Special-effects
(abbr. SXF) projectors can transport the audience out of the dome
and set the scene for the producer.
- While the video projection of effects can eliminate the need
for certain specialized projectors, other effects still require
individual attention, especially "whole-dome" environments such as
clouds, snow, meteor showers, and supernovas.
- Special-effects projectors also deliver an image of far
greater resolution than is possible with video.
Examples
We have dedicated special-effects projectors for the following
whole-dome effects:
- Anamorphic lens (2)
- Image rotators (2)
- Clouds (2)
- Lightning (1)
- Meteor shower (1)
- Snow (2)
- Bolide (1)
- Supernova (1)
- Ripple wheel effect
- Strobes (3)
Planned for Phase II: Rain (1); Diffusion lens (2); Zoom lens (1);
X-Y mirror (2)
Control: Special-effects projectors are controlled by Dubhe boxes,
Pollux boxes, or Break-Out-Boxes. Each of these three kinds of boxes
is controlled by a Gemini. See the manuals for more information.
Localized video special effects.
Video projection is used for localized special effects such as the
following:
- Solar System motion
- Lunar and Solar Eclipses
- Rotating planets, galaxies
- Solar flares
- Orbiting satellites and spacecraft
- And many, many more....
