Paleontolog Nick Pyenson byl v zoufal\u00e9m z\u00e1vod\u011b se stavebn\u00edm t\u00fdmem. Pod jejich lopatkami le\u017eel poklad velryb\u00edch fosili\u00ed a on m\u011bl jen n\u011bkolik dn\u00ed na jejich z\u00e1chranu. S ub\u00fdvaj\u00edc\u00edm \u010dasem se Pyenson obr\u00e1til na nepravd\u011bpodobn\u00e9ho spojence: 3D digitaliza\u010dn\u00ed t\u00fdm Smithsonianu.<\/p>\n\n
Vince Rossi a Adam Metallo, zn\u00e1m\u00ed jako \u201elaserov\u00ed kovbojov\u00e9\u201c, p\u0159ijeli do Chile se sv\u00fdmi \u0161pi\u010dkov\u00fdmi laserov\u00fdmi skenery. Jejich mise: vytvo\u0159it virtu\u00e1ln\u00ed modely velryb\u00edch fosili\u00ed v jejich p\u016fvodn\u00edch poloh\u00e1ch. Tyto modely by v\u011bdc\u016fm umo\u017enily studovat toto m\u00edsto nav\u017edy, i pot\u00e9, co budou kosti odstran\u011bny.<\/p>\n\n
Rossi a Metallo pe\u010dliv\u011b sledovali velryby lasery, jejich pa\u017ee bolely po dnech nam\u00e1hav\u00e9 pr\u00e1ce. Digit\u00e1ln\u00ed avata\u0159i, kter\u00e9 vytvo\u0159ili, byly neuv\u011b\u0159iteln\u011b detailn\u00ed a odhalovaly anatomii velryb s neb\u00fdvalou p\u0159esnost\u00ed.<\/p>\n\n
Pomoc\u00ed digit\u00e1ln\u00edch sken\u016f a vzork\u016f hornin se Pyenson pustil do p\u00e1tr\u00e1n\u00ed po tajemstv\u00ed t\u011bchto starov\u011bk\u00fdch velryb. Prozkoumal oran\u017eov\u00e9 \u0159asy na n\u011bkter\u00fdch fosili\u00edch, co\u017e je potenci\u00e1ln\u00ed vod\u00edtko k jejich z\u00e1niku. Analyzoval tak\u00e9 star\u00e9 mo\u0159sk\u00e9 dno a hledal d\u016fkazy o tsunami nebo \u00fatoc\u00edch \u017eralok\u016f.<\/p>\n\n
Dnes byly velryb\u00ed fosilie odstran\u011bny z m\u00edsta, jejich m\u00edsta odpo\u010dinku byla vymaz\u00e1na. Ale d\u00edky laserov\u00fdm sken\u016fm mohou Pyenson a jeho kolegov\u00e9 st\u00e1le prozkoum\u00e1vat tento starov\u011bk\u00fd h\u0159bitov virtu\u00e1ln\u011b. Mohou studovat polohy velryb, jejich zran\u011bn\u00ed a okoln\u00ed prost\u0159ed\u00ed, co\u017e vrh\u00e1 sv\u011btlo na jejich \u017eivoty a smrt.<\/p>\n\n
Digit\u00e1ln\u00ed modely slou\u017e\u00ed tak\u00e9 jako d\u016fle\u017eit\u00fd n\u00e1stroj pro uchov\u00e1n\u00ed.
