Una delle restrizioni di IRIS GL era che forniva accesso solamente alle caratteristiche supportate dall'hardware soggiacente. Se l'hardware grafico non supportava una caratteristica, allora l'applicazione non poteva usarla. OpenGL ha superato questo problema fornendo supporto via software per le caratteristiche non supportate dall'hardware, permettendo alle applicazioni di usare della grafica avanzata su sistemi di potenza relativamente bassa. Il progetto Fahrenheit fu uno sforzo congiunto fra Microsoft, SGI, e Hewlett-Packard con l'obiettivo di unificare le interfacce OpenGL e Direct3D. Inizialmente ha mostrato qualche promessa di portare ordine nel mondo delle API di computer grafica 3D interattiva, ma a causa dei vincoli finanziari in SGI e alla generale carenza di supporto nell'industria, è stato poi abbandonato. ==== OpenGL 1.0 ==== Pubblicato nel [[1992]]. La prima specifica di OpenGL fu pubblicata da Mark Segal e Kurt Akeley. ==== OpenGL 1.1 ==== Pubblicato nel gennaio [[1997]]. OpenGL 1.1 si prefigge di supportare funzioni texture e formati texture su GPU hardware. * Schede: ''tutte'' ==== OpenGL 1.2 ==== Pubblicato il 16 marzo [[1998]]. OpenGL 1.2 si prefigge di supportare funzioni di ''volume textures'', ''packed pixels'', ''normal rescaling'', ''clamped/edge texture sampling'' e ''image processing''. * Schede: Rage 128, Rage 128 GL, Rage XL/XC, Rage 128 Pro, Rage Fury MAXX e successive. ===== OpenGL 1.2.1 ===== Pubblicato il 14 ottobre [[1998]]. OpenGL 1.2.1 è una pubblicazione intermedia che aggiunge funzioni di multi-texture, o anche texture units, al rendering pipeline. Ciò permette di mescolare textures multiple sulla base di pixel, durante la rasterizzazione. * Schede: Radeon, Radeon Mobility, Radeon 7500 Mobility, Radeon 8500, Radeon 9000, Radeon 9200, Radeon 9600, Radeon 9800, GeForce 3, GeForce 4Ti, GeForce FX e successive. ==== OpenGL 1.3 ==== Pubblicato il 14 agosto [[2001]]. OpenGL 1.3 aggiunge il supporto per funzioni di cubemap texture, multi-texturing, multi-sampling, e funzioni di texture unit combine operations (come: add, combine, dot3 e border clamp). * Schede: Radeon 32/36, Radeon 64/7200, Radeon 7000, Radeo AIW, Radeon 7500, Radeon IGP 320M, Radeon IGP 345M, ES1000, Radeon 8500, Radeon 9000/Pro, Radeon 9100/9200/9250 (Pro & IGP), GeForce 3, GeForce 4Ti, GeForce FX e successive. ==== OpenGL 1.4 ==== Pubblicato il 24 luglio [[2002]]. OpenGL 1.4 introduce il supporto hardware per funzioni di shadowing, fog coordinates, automatic mipmap generation, e funzioni addizionali di texture. * Schede: Quadro DCC, Quadro4 380 XGL, Quadro4 500XGL, 550XGL, Quadro4 700XGL, 750XGL, 900XGL, 980XGL e successive. ==== OpenGL 1.5 ==== Pubblicato il 29 luglio [[2003]]. OpenGL 1.5 aggiunge supporto per: vertex buffer objects (VBOs), occlusion queries, e extended shadowing. * Schede: Radeon X800, Radeon 9600, Radeon 9700, Radeon 9800, GeForce FX, e successive. </textarea><div class="templatesUsed"></div><p id="mw-returnto">Torna a <a href="/wiki/OpenGL" title="OpenGL">OpenGL</a>.</p> <noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1&useformat=desktop" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Estratto da "<a dir="ltr" href="https://it.wikipedia.org/wiki/OpenGL">https://it.wikipedia.org/wiki/OpenGL</a>"</div></div> <div id="catlinks" class="catlinks catlinks-allhidden" data-mw="interface"></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> </ul> <ul id="footer-places"> <li id="footer-places-privacy"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Privacy_policy/it">Informativa sulla privacy</a></li> <li id="footer-places-about"><a href="/wiki/Wikipedia:Sala_stampa/Wikipedia">Informazioni su Wikipedia</a></li> <li id="footer-places-disclaimers"><a href="/wiki/Wikipedia:Avvertenze_generali">Avvertenze</a></li> <li id="footer-places-wm-codeofconduct"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Universal_Code_of_Conduct">Codice di condotta</a></li> <li id="footer-places-developers"><a href="https://developer.wikimedia.org">Sviluppatori</a></li> <li id="footer-places-statslink"><a href="https://stats.wikimedia.org/#/it.wikipedia.org">Statistiche</a></li> <li id="footer-places-cookiestatement"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Cookie_statement">Dichiarazione sui cookie</a></li> <li id="footer-places-mobileview"><a href="//it.m.wikipedia.org/w/index.php?title=OpenGL&action=edit&section=4&mobileaction=toggle_view_mobile" class="noprint stopMobileRedirectToggle">Versione mobile</a></li> </ul> <ul id="footer-icons" class="noprint"> <li id="footer-copyrightico"><a href="https://wikimediafoundation.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/static/images/footer/wikimedia-button.svg" width="84" height="29" alt="Wikimedia Foundation" loading="lazy"></a></li> <li id="footer-poweredbyico"><a href="https://www.mediawiki.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/w/resources/assets/poweredby_mediawiki.svg" alt="Powered by MediaWiki" width="88" height="31" loading="lazy"></a></li> </ul> </footer> </div> </div> </div> <div class="vector-settings" id="p-dock-bottom"> <ul></ul> </div><script>(RLQ=window.RLQ||[]).push(function(){mw.config.set({"wgHostname":"mw-web.codfw.main-5c59558b9d-kqnj8","wgBackendResponseTime":177,"wgPageParseReport":{"limitreport":{"cputime":"0.004","walltime":"0.005","ppvisitednodes":{"value":17,"limit":1000000},"postexpandincludesize":{"value":803,"limit":2097152},"templateargumentsize":{"value":0,"limit":2097152},"expansiondepth":{"value":2,"limit":100},"expensivefunctioncount":{"value":0,"limit":500},"unstrip-depth":{"value":0,"limit":20},"unstrip-size":{"value":0,"limit":5000000},"entityaccesscount":{"value":0,"limit":400},"timingprofile":["100.00% 0.000 1 -total"]},"cachereport":{"origin":"mw-web.codfw.main-5c59558b9d-kqnj8","timestamp":"20241129072823","ttl":2592000,"transientcontent":false}}});});</script> </body> </html>
