This file is a stereogram. Stereograms are stereoscopic images or animations which combine left and right frames showing slightly different visual angles to allow for 3D perception.
The stereogram uses an anaglyphic method of stereoscopic 3D presentation which is unspecified or unrecognized by this template. (If a suitable option is available, please add or correct the parameters to indicate the type of anaglyph used.) Some type of two-color 3D glasses are recommended to view this image correctly.
Summary
DescriptionAstro 4D uma rg anim.gif
English: The Big Ripper - the movement of stars in -/+ 150 000 years.
To view this picture you need 3D glasses (red-green or red-blue).
Slovenčina: 4D pohyb hviezd Veľkého voza za -/+ 150 000 rokov.
Na prezeranie tejto animácie sú potrebné 3D okuliare s farebnými filtrami červená-zelená, príp. sa dá dosiahnuť uspokojivý výsledok aj červeno-modrými okuliarmi, pritom záleží aj na poradí farieb: červenú farbu treba mať pred ľavým okom, zelenú alebo modrú pred pravým.
Hĺbka 3D priestoru je modifikovaná logaritmicky, t.j. hviezdy, ktoré sa nám javia na dvojnásobnú vzdialenosť, sú v skutočnosti vzdialené až 10-násobne.
