Ekuqaleni kwale nyanga sithumele lapha kubhulogi mayelana nezindaba zokuthi uNvidia uthathe isinqumo sokukhipha ikhodi yomthombo weNvidia PhysX uma ufuna ukwazi kabanzi ngalo ungavakashela isixhumanisi esilandelayo.
Futhi, njengoba kushiwo kuleyo ndatshana, lAbathuthukisi beNvidia baqhubeke nokusebenza ekuthuthukiseni injini yabo yePhysX.
Lapho abantu baseNVIDIA basanda kukhipha inguqulo entsha yenjini yabo ye-PhysX 4.0, okwakuwukukhishwa kokuqala okukhulu ngemuva kokuhumusha esigabeni sephrojekthi esivulekile.
Ngasikhathi sinye, ukukhishwa kwesibuyekezo sePhysX 3.4.2, kufaka phakathi izinguquko zokulungisa isisekelo sekhodi esivulekile ekuqaleni.
Mayelana neNvidia PhysX
Ikhodi yephrojekthi isatshalaliswa ngaphansi kwelayisense le-BSD futhi iyahambisana nezingxenyekazi zeLinux, MacOS, iOS, Windows ne-Android.
Isidingo sokusayina isivumelwano esishiywe yi-EULA ngenkathi kwakhiwa amapulatifomu eXBox One, iSony Playstation 4 neNintendo switch.
Ngaphezu kwenjini ngqo ngaphansi kwelayisense le-BSD, ikhodi nethuluzi lamathuluzi le-PhysX SDK elihlobene nalo livulekile.
I-PhysX ingenye yezinjini ze-physics ezidume kakhulu ezibandakanyeka ekucubunguleni ukuxhumana komzimba emidlalweni engaphezu kwama-500 futhi kuyingxenye yezinjini eziningi zemidlalo, njenge-Unreal Engine, Unity3D, AnvilNext, Stingray, Dunia 2, neREDengine.
Injini iyasebenziseka kumakhompyutha ahlukahlukene, kusuka kuma-Smartphones kuya eziteshini ezinamandla zokusebenza ezinama-CPU amaningi nama-GPUs, ikuvumela ukuthi usebenzise ngokugcwele amakhono we-GPU ukusheshisa ukucutshungulwa kwemiphumela.
Phakathi kwezindawo ezisetshenziswa i-PhysX, singasho ukuqaliswa kwemiphumela efana nokubhujiswa, ukuqhuma, ukunyakaza okungokoqobo kwezinhlamvu nezimoto, intuthu evela kumagagasi, izihlahla ezigoqwe ngumoya, ukuchitheka kwamanzi nokugeleza kuzungeze izithiyo, ukugeleza nokudiliza okwezingubo, ukushayisana nokuxhumana nemizimba elukhuni nethambile.
I-NVIDIA ilindile lokho ngemuva kokudluliswa iphrojekthi esigabeni esivulekile, uzokwazi ukudlula amathuluzi wokuthuthukisa umdlalo futhi izofunwa ezindaweni ezifana nokwenziwa kwedatha yocwaningo lobunhloli bokufakelwa nokuqeqeshwa kwenethiwekhi ye-neural, ukudala izindawo ezingokoqobo zamarobhothi okuqeqesha.
Ukulingiswa kwezimo zangempela ngenkathi kuqhutshwa izimoto ezizimele kanye nama-autopilots. Ukuvumelanisa injini nezinhlelo zamaqoqo asebenza kakhulu kulindeleke ukuthi kufinyelele ezingeni elisha lemininingwane nokunemba ekulingiseni izinqubo zomzimba.
Izici Zokukhishwa ze-PhysX 4.0
Ngalokhu kwethulwa kwenjini yakho entsha, Izici ezintsha zingeziwe kuphrojekthi kanye nokulungiswa kwamaphutha okuhlukahlukene.
Ngaphezu kwalokho, ngalokhu abantu baseNvidia banethemba lokuthi abanye abaningi bazojoyina ukuthuthukiswa kwephrojekthi.
Ngalokhu kukhululwa okusha ukuqaliswa kwe-algorithm ye-TGS kugqanyisiwe (Temporal Gauss-Seidel Solver), evumela ukuthuthukisa ikhwalithi yokulingiswa kwezinhlamvu nezinto, eziqukethe izingxenye eziningi ezichaziwe.
Ngaphandle kwalokho uhlelo lokwakha luhunyushelwe ukukwazi ukusebenzisa iCmake.
Kule nguqulo entsha ye-PhysX 4.0, ungabona ukukhululeka okukhulu kwemithetho yokuhlunga yezinto ezi-kinematic neze-static.
Futhi lokho futhi isigaba esisha sokutholwa kokushayisana kwe-ABP sengezwe kuphrojekthi (okuzenzakalelayo multiphase), okuvunyelwe ezimweni eziningi ukuthuthukisa ukusebenza kwenjini.
Ngakolunye uhlangothi, umsebenzi olinganiselayo wokulingisa ohlanganisiwe owenziwe lula (ukuhlanganiswa kokuxhumanisa okuncishisiwe) kungeziwe, ngaphandle kwephutha lokuma okuhambisanayo futhi elifanele ukulingisa okungokoqobo kokuhamba ngokuhlanganyela.
Ngalokho futhi kwethulwa isakhiwo esisha se-BVH, sikhombisa ukusebenza okungcono kwezinhlamvu ezinenani elikhulu kakhulu lamajamo.
Ekugcineni, okususwe kule nguqulo entsha yephrojekthi ukusekelwa kwezinhlayiya ze-PhysX nePhysX Cloth, eseziyekisiwe futhi abathuthukisi abaliboni icala lokuqhubeka nokuyixhasa.
