Sažetak

Računalno generirani vizualni efekti omogućavaju novu dimenziju prikaza i vizualizacije u grafičkoj tehnologiji i sve češće se pojavljuju u svakodnevnom životu. Njihova pojava uzrokovana je naglim razvojem grafičke tehnologije u polju računalnih znanosti pa time i računalne grafike. Time grafička tehnologija u simbiozi s računarstvom ulazi u područje multimedijskih komunikacija u svrhu razvoja računalne grafike i animacije. Područja vizualne računarske znanosti razvijaju se velikom brzinom i nalaze svoju primjenu u inženjerstvu, znanosti, medicini, vojnim primjenama i umjetnosti.
Danas je metoda klasičnog animiranog filma prevladana 3D animacijom zbog dramatične zastupljenosti računalne tehnologije, no principi klasične animacije nisu posve zanemareni. U računalnoj animaciji najbolje rezultate postižu autori i animatori školovani po principima klasične animacije, jer oni poznaju tehničke principe koje je moguće primijeniti na bilo kojem konfiguracijskom obrascu. Precizno znanje klasične tehnologije danas je od nezaobilazne važnosti više nego ikad i to u fazi projekta jer upravo računalna animacija dopušta daleko više improvizacije od klasične.

Abstract

Visual effects that allow a new dimension to display different objects, are increasingly appearing in daily life. Their appearance is caused by the rapid development of technical sciences and computer graphics. The frequently asked question is how do they achieve these visual effects, 3D animation and virtual reality. All of these are products of computer graphics and animation, visual areas of computer science that is developing at a breathtaking speed, and are used in engineering, science, medicine, arts, and military applications.
Nowdays 3D animation has overcome method of classical animation because of growing presence of computer technology, but principles of classical animation are not completely ignored. In computer animation, the best results are achieved by the authors and animators trained by principles of classical animation, because they know the technical principles that can be applied to any configuration form. Precise knowledge of the classical techniques today is more important than ever, especially in the phase of the project because the computer animation allows far more improvisation than classical. Basic principles of traditional animation defined by the Walt Disney Studios before nearly 80 years are now also used in 3D animation [3].
Keywords: Autodesk Maya, animation theories of human figures, skeletal animation, forward kinematics, inverse kinematics, skinning, weighting, rigging

 

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.
