▁Dynamic ▁simpl ification ▁for ▁pol yg onal ▁models ▁In ▁ 1 9 9 6 , ▁Var sh ney ▁published ▁an ▁algorithm ▁for ▁real - time ▁simpl ifications ▁of ▁pol yg ons ▁in ▁a ▁ 3 - dimensional ▁model : ▁ ▁A ▁continuous ▁level - of - detail ▁representation ▁for ▁an ▁object ▁is ▁first ▁constructed ▁off - line . ▁This ▁representation ▁is ▁then ▁used ▁at ▁run - time ▁to ▁guide ▁the ▁selection ▁of ▁appropriate ▁tri angles ▁for ▁display . ▁The ▁list ▁of ▁displayed ▁tri angles ▁is ▁updated ▁increment ally ▁from ▁one ▁frame ▁to ▁the ▁next . ▁Our ▁approach ▁is ▁more ▁effective ▁than ▁the ▁current ▁level - of - detail - based ▁rendering ▁approaches ▁for ▁most ▁scientific ▁visual ization ▁applications ▁where ▁there ▁are ▁a ▁limited ▁number ▁of ▁highly ▁complex ▁objects ▁that ▁stay ▁relatively ▁close ▁to ▁the ▁vie wer . ▁ ▁Opt im izing ▁triangle ▁stri ps ▁Also ▁in ▁ 1 9 9 6 , ▁Var sh ney ▁published ▁" Opt im izing ▁Tri angle ▁St ri ps ▁for ▁Fast ▁Render ing ". ▁The ▁study ▁introduced ▁new ▁algorithms ▁for ▁rendering ▁triangle ▁stri ps ▁in ▁conj unct ure ▁with ▁partially ▁tri ang ulated ▁models . ▁Descri bing ▁their ▁more ▁efficient ▁triangle ▁strip ▁algorithm , ▁Var sh ney ▁et ▁al . ▁write : ▁ ▁By ▁using ▁triangle ▁stri ps ▁... ▁, ▁we ▁can ▁describe ▁the ▁tri ang ulation ▁using ▁the ▁strip ▁... ▁and ▁assuming ▁the ▁convention ▁that ▁the ▁it h ▁triangle ▁is ▁described ▁by ▁the ▁it h , ▁( i ▁+ ▁ 1 ) st , ▁and ▁(
