IRIX na Voodoo: Amateka Mugufi yubufatanye budashoboka

Mu myaka ya za 90 rwagati, isi yo kubara yari ahantu h'irushanwa rikomeye no guhanga udushya. Ku ruhande rumwe hari Silicon Graphics, Inc. Kurundi ruhande, isoko ryimikino yo kugura PC y'abaguzi ryagendaga rihindurwa n'ikarita ntoya kuva 3dfx Interactive: Voodoo Graphics. Iyi yihuta ya 3D yihuta yazanye ibishushanyo mbonera bya arcade kuri desktop, ikoreshwa na nyirayo Glide API. Kubakunzi hamwe nabateza imbere, havutse ikibazo cyo gutesha umutwe: byagenda bite niba imbaraga mbisi, zishingiye kumikino za Voodoo zishobora gukoreshwa mubidukikije bigoye, bishingiye kuri UNIX bya IRIX? Igisubizo cyari umushinga uyobowe nabaturage wohereza isomero rya Glide (glide2x) kuri IRIX, ugakora ikiraro hagati yisi ebyiri zisa nkizitandukanye nisi yo kubara.

Ikibazo cya Tekinike yo Gutwara Glide kuri IRIX

Gutwara glide2x kuri IRIX byari umurimo wubwubatsi bwa software. Glide yashizweho nk'urwego ruto, rwihariye rwa DOS na Windows, ruvugana na rasterizer ya Voodoo hamwe no gushushanya ibice. IRIX, ariko, yari ifite urusobe rwibinyabuzima rukuze kandi rugoye, rwubatswe hafi ya IRIS GL hanyuma nyuma ya OpenGL APIs, kandi rwinjizwamo cyane na SGI yonyine ibyuma byo mu rwego rwo hejuru byerekana amashusho nka InfiniteReality. Abatwara ibicuruzwa bagombaga gukora urwego rwubuhinduzi rushobora guhagarika guhamagara Glide API no kubishushanya kuri sisitemu ya IRIX hamwe na moderi zo kwibuka. Ibi byari bikubiyemo reaction-yubuhanga, byitondewe byo murwego rwohejuru, hamwe no gusobanukirwa byimbitse kubikorwa byo kwiyandikisha kurwego rwa Voodoo hamwe na IRIX ya UNIX intangiriro na sisitemu ya X11. Intsinzi yashakaga kuvuga ko, kunshuro yambere, ikarita ya Voodoo yashoboraga kumenyekana no gukoreshwa nkigikoresho cyo gutanga mu biro bya SGI, igikorwa cyigeze gutekereza ko kidashoboka.

Umuryango, Hobbyist, hamwe numwuka wo kwikuramo

Iki gikorwa ntabwo cyari umurimo wikigo. Byayobowe gusa numuryango wihaye abakunzi ba SGI, abahindura-injeniyeri, na programmes babonye ikibazo cya tekiniki n'amahirwe adasanzwe. Ihuriro kumurongo, urutonde rwubutumwa, nurubuga rwo hambere rwabaye ihuriro ryo gusangira ibice, binary, nubumenyi bwatsindiye. Impamvu yari ifite impande nyinshi: gukoresha imikino gakondo ishingiye kuri Glide nka "Quake," "Tomb Raider," na "Kumanuka" ku byuma bidasanzwe; Kugerageza na Hybrid yashizeho; no kwerekana gusa ko byakorwa. Ubu buryo bwo gufatanya, muburyo bwo gukemura ibibazo-gutondekanya hamwe umushoferi ukora kuva mumisanzu yabaturage - birerekana filozofiya ya Mewayz igezweho, aho ibice bya software bihuza bihuza kugirango habeho sisitemu yubucuruzi ihuriweho ijyanye nibyifuzo byihariye.

"Umushinga wo gutwara ibinyabiziga wa IRIX Voodoo wari igihamya cy'imyitwarire ya ba hackers. Byari bijyanye no gukora ibice bibiri by'ikoranabuhanga byiza, bitigeze bigenerwa gukorera hamwe, kuririmbira mu bwumvikane. Buri mpanuka yajugunywe hamwe na mpandeshatu ya Glide yatanzwe neza yumvaga ari intsinzi."

Umurage n'akamaro ka kijyambere

Mugihe ikoreshwa ryikarita ya Voodoo muri sisitemu ya IRIX ryahoraga ari ryiza, umurage wumushinga urakomeye. Yerekanye imbaraga ziterambere ryugururiwe abaturage, kandi ryagura ubuzima bwingirakamaro bwibikoresho bya SGI bihenze kubakunda. Uyu munsi, ihagaze nkurupapuro rushimishije mumateka ya mudasobwa, yerekana igihe cyubushakashatsi budasanzwe. Kubateza imbere muri iki gihe hamwe na sisitemu yububiko, ikora nkibutsa akamaro ka sisitemu yo guhuza n'imiterere, yanditse neza. Mubucuruzi bugezweho, kwifungisha muri porogaramu imwe, ikomeye ya software irashobora kugabanuka nkibikoresho byihariye. Aha niho urubuga rwa modular nka Mewayz rutanga inyungu zingenzi, zemerera ubucuruzi guhuza ibikoresho-byiza-by-ibikoresho hamwe na sisitemu yumurage mubikorwa bihuriweho, kimwe nabaterankunga ba mbere badoda hamwe Glide na IRIX.

Ibyingenzi byagezweho muri IRIX Voodoo / Glide porting imbaraga zirimo:

• Gushoboza ibyuma byihuta byerekana porogaramu ya Glide kuri sisitemu ya SGI Indy, O2, na Octane.
• Gutanga isomero ikora, umukoresha-umwanya wibitabo (glide2x.so) byahujwe na moderi yimikorere yihariye.
• Gushyigikira ibishushanyo bitandukanye bya Voodoo, harimo Graphics yumwimerere ya Voodoo hanyuma ikibaho cya Voodoo2 muri SLI.
• Gutezimbere ubumenyi bwibanze nyuma yamenyesheje isoko-ya GPU iteza imbere no gutwara imishinga.

Ubwanyuma, inkuru yumushoferi wa IRIX Voodoo ntabwo irenze amatsiko ya tekiniki. Nibisobanuro byerekeranye no gukemura icyuho, haba hagati yumuguzi nubuhanga bwumwuga, cyangwa hagati yimikorere itandukanye. Muri iki gihe imiterere ya digitale, ubushobozi bwo guhuza sisitemu zitandukanye ntabwo ari kubakunda gusa - ni itegeko mubucuruzi. Ihuriro ryakira iyi filozofiya isanzwe, ihuriweho, nka Mewayz , iha imbaraga amashyirahamwe kubaka ibidukikije byiza byayo bitabujijwe n'imbogamizi z'ikoranabuhanga iryo ari ryo ryose.
