  • Animatsiooni Töövõtted Ja Terminid
    Multimeedium, 2D animatsioon Animatsiooni töövõtted ja terminid Nii 2D kui ka 3D animatsioonide juures kasutatakse mitmeid samu võtteid ja termineid. Mõned neist on järgnevas lahtiseletatud. Keyframe Keyframe ehk võtmekaader on selline kaader, millel autor määrab objekti(de) täpse asukoha, suuruse, kuju, värvuse jms. antud ajahetkel. Kaadrid kahe keyframe vahel genereeritakse tavaliselt animatsiooniprogrammi poolt Keyframe 1 Keyframe 2 keerukate arvutuste tulemusena. Traditsioonilise animeerimise korral joonistavad peakunstnikud vajalikud keyframe'id ning nende assistendid kõik ülejäänu. Tracing Tracing on meetod uue kaadri loomiseks eelmise või vahel ka järgmise kopeerimise (trace) teel. Kopeeritava kujutise näitamiseks kasutatakse mitmeid meetodeid, sealhulgas aluseks oleva kujutise näitamine teise värviga, sageli sinisega. Tweening Tweening on tehnika, mis etteantud keyframe'ide vahele genereerib kasutaja poolt etteantud arvu kaadreid, millede jooksul toimub järkjärguline üleminek esimeselt keyframe'ilt teisele. Võttes arvesse kahe keyframe'i erinevusi, kalkuleerib arvuti iga kaadri jaoks proportsionaalsed muudatused objektide asukoha, suuruse, värvuse, kuju jms jaoks. Mida rohkem kaadreid lastakse genereerida, seda väiksemad tulevad järjestikuste kaadrite vahelised erinevused ning seda sujuvam tuleb liikumine. Keyframe 1 genereeritud kaadrid Keyframe 2 Rendering Rendering on protsess, mille käigus objektide traatmudelid (wireframe vahel ka mesh) kaetakse pinnatekstuuridega, neile lisatakse valgusefektid ja värvid, et saada realistlik

The pace of improvement in clock speeds and architectural sophistication is slowing, and while single-threaded performance continues to improve, the focus has shifted to multicore designs. These too are reaching practical limits for personal computing; a quad-core CPU isn’t worth twice the price of a dual-core, and chips with even higher core counts aren’t likely to be a major driver of value in future PCs. CPUs will never go away, but GPUs are assuming a more prominent role in PC system architecture.

The single processor era has been replaced with multi-core processors, which have quickly been surrounded by satellite devices aiming to increase the throughput of the entire system. These auxiliary devices, such as Graphics Processing Units, Field Pro- grammable Gate Arrays or other specialized processors have very different architectures. This puts an enormous strain on programming models and software developers to take full advantage of the computing power at hand.
