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
| Description |
English: The movement of stars around the apex (left) and antapex (right) in -/+ 500 000 years.
To view this picture you need 3D glasses (red-green or red-blue).
Slovenčina: 4D animácia pohybu hviezd na oblohe za -/+ 500 000 rokov.
Vľavo sa nachádza apex - zdanlivý smer pohybu Slnka v galaxii. Zdá sa nám, akoby sme vleteli do hviezdneho roja: všetko nás míňa okolo. Vpravo je antapex - akoby sme prichádzali z tohto smeru, akoby sme sa pozerali na okolie cez zadné okno auta: všetko sa stráca v diaľach. Pozn.: hĺbka 3D priestoru je modifikovaná logaritmicky, t.j. hviezdy, ktoré sa nám javia na dvojnásobnú vzdialenosť, sú v skutočnosti vzdialené až 10-násobne. 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. |
