Sažetak

Razvojem novih tehnologija omogućeno je brzo i kvalitetno trodimenzionalno modeliranje te ispis trodimenzionalnih objekta direktno iz računala na 3D pisač ili 3D graviranje unutar stakla. Trodimenzionalni model je moguće dobiti različitim tehnikama skeniranja objekata uz pomoć 3D skenera te se na taj način dobiva neka vrsta 3D fotokopiranja stvarnog objekta ili trodimenzionalnim modeliranjem nekim od komercijalnih alata za modeliranje. Postoje različiti uređaji za 3D ispis ovisno o materijalu i namjeni za koju se koriste. Cilj ovog rada je opisati principe 3D skeniranja objekta provedenih ručnim i laserskim skenerom. Za ručno skeniranje, upotrebljavati će se ručni skener Artec MHT 3D sa Artec 3D studio softver. Za lasersko skeniranje će se koristiti skener NextEngine koji skenira objekt snopom laserskih zraka. Nakon skeniranja i obrade odgovarajućim softverima, dobit će se 3D model istog objekta na dva načina skeniranja. Svrha istraživanja je napraviti detaljnu analizu dobivenih modela i to s aspekta kvalitete skeniranja i dorade modela. Dobiveni 3D modeli će se koristiti za potrebe laserskog graviranja unutar kristalnog stakla, te će se kvalitativnom analizom utvrditi koji je 3D model kvalitetniji.
Ključne riječi: 3D model, 3D skeneri, 3D graviranje unutar kristalnog stakla, Artec MHT 3D i NextEngine.

The comparison of the Artec and Nextengine 3D scanner in the process of a 3D modelling

Abstract

With the development of new technologies a fast and quality 3D modelling is enabled, as well as the printing of 3D objects directly from the computer on the 3D printer or 3D glass engraving. The 3D model can be obtained by various object scanning techniques using the 3D scanner and can in this way result in a kind of 3D photocopying of the real object or with a 3D modelling by some of the commercial modelling tools. The aim of this paper is to describe the 3D object scanning principles conducted by the manual and laser scanner. For manual scanning, the manual Artec MHT 3D scanner will be used, along with the Artec 3D studio software. For the laser scanning, the NextEngine scanner, that scans the object with laser beams, will be used. After the scanning and elaboration with appropriate software, a 3D model of the same object will be obtained in two ways of scanning. The purpose of the research is to elaborate a detailed analysis of the resulting models from the aspect of scanning quality and model processing. The resulting 3D models will be used for glass engraving inside crystal glass and a quality analysis will determine which 3D model is better.
Key words: 3D model, 3D scanners, 3D engraving inside crystal glass, Artec MHT 3D and NextEngine.


Patrik Ervells latest collection is ironically titled “Software”ADIDAS ORIGINALS TUBULAR SHADOW. In the notes from the presentation, Ervell says he was interested in developing tension between nostalgia and sci-fi,NIKE ZOOM WINFLO 3 and even included 90s cyberpunk amongst his influences. Ervell developed this point of view by creating an imaginary software company called Idegen software systems. He then re-appropriated the company’AIR JORDAN XXXI MENs logo in several of the collection’s garments. Elsewhere,MBT TARIKI MEN mohair coats with oversized lapels made an appearance alongside mock neck tees,NIKE AIR JORDAN RETRO 5 police-inspired ribbed sweaters,MBT FORA GTX WOMEN flight bombers, and polyurethane leather coats. The setting was also suitably dystopian, and the resulting ambiance was something akin to if the creators of Deutschland 83 and Hackers met up and decided to create a collection… We mean that as a compliment.Yesterday afternoon,JORDAN CP3 IX MEN artist JR spent the day working on his latest collaborative piece with Daniel Arsham in Greenpoint,NIKE AIR MAX 90 Brooklyn,MBT KIMONDO GTX MEN NYC. Connecting the lines between art, architecture, dance and theater, Daniel Arsham has been known to subvert existing architectural structures in unconventional,NIKE CLASSIC CORTEZ NYLON playful ways; confusing and confounding the expectations of space and form.
