Imibuzo Evame Ukubuzwa

Kungani i-Vulkan ithathwa njengobunzima ukuyifunda uma iqhathaniswa ne-OpenGL?

I-Vulkan idinga onjiniyela ukuthi baphathe imininingwane yeleveli ephansi i-OpenGL eyiphatha ngokuzenzakalela, okuhlanganisa ukwabiwa kwememori, ukuvumelanisa, nokuqoshwa kwebhafa yomyalo. Lokhu kulawula okucacile kunikeza ukusebenza okungcono kodwa kwandisa ikhodi ye-boilerplate kakhulu. Ukwephula i-Vulkan ibe amasistimu angaphansi ahlukanisiwe - njengokuphathwa kwe-swapchain, amasethi ezichazi, nokudala amapayipi - kwenza ucezu ngalunye lube lula ukuluqonda nokusebenzisa ngokuqhubekayo esikhundleni sokubhekana nayo yonke i-API ngesikhathi esisodwa.

Isho ukuthini "isistimu engaphansi eyodwa ngesikhathi" ekusebenzeni?

Kusho ukuhlukanisa ingxenye ye-Vulkan ngayinye ibe yimojuli eziqukethwe ngokwayo enokufakwayo okucacile kanye nokuphumayo. Isibonelo, uphatha ukuqaliswa kwedivayisi ngokuhlukene kusukela ekwenzeni iphasi, kanye nokuphathwa kwebhafa yomyalo ongabonakali kude namakholi wokudonsa. Le ndlela yokulinganisa yehlisa umthwalo wokuqonda futhi yenza ukulungisa iphutha kube lula kakhulu, njengoba izinkinga zingalandelelwa kusistimu encane ethile kunokuzingela ngezinkulungwane zemigqa yekhodi yokusetha exhumene.

Amamojula akhiwe ngaphambilini angasheshisa kanjani ukuthuthukiswa kwe-Vulkan?

Amamojula akhiwe ngaphambilini asusa isidingo sokubhala i-boilerplate ephindaphindayo kusukela ekuqaleni kuyo yonke iphrojekthi. Amapulatifomu afana ne-Mewayz anikela ngamamojula enziwe ngomumo angama-207 aqala ku-$19/mo, ahlanganisa amaphethini avamile kuwo wonke ukuhlelwa kwezithombe nezinye izizinda. Ku-Vulkan ngokuqondile, ukuba nezifinyezo ezihloliwe zezinhlelo ezingaphansi ezifana nokugcinwa kwesikhashana kwephayiphi, ukuphathwa kwechibi lesichazi, nokuvumelanisa kozimele kuvumela onjiniyela ukuthi bagxile kumqondo wokunikezela oqondene nohlelo lokusebenza esikhundleni sokusungula kabusha ingqalasizinda.

Ingabe ukwenza i-Vulkan ibe lula kuwufanele umzamo ngaphezu kokusebenzisa nje injini yegeyimu?

Kuya ngezinhloso zakho. Izinjini zegeyimu zifihla ubunkimbinkimbi be-Vulkan kodwa zikhawulela ukulawula okunomphumela omuhle phezu kwamapayipi okunikezela kanye nokuphathwa kwezisetshenziswa ze-GPU. Ukwenza lula i-Vulkan ngokwakho kukunikeza ubunikazi obugcwele bokuthuthukiswa kokusebenza, amasu okunikeza ngokwezifiso, kanye nesikhathi esincane sokusebenza. Emaqenjini akha amathuluzi akhethekile, isofthiwe yokulingisa, noma izinjini zokwenza ngokwezifiso, ukutshala imali ezintweni ezifushanisiwe ze-Vulkan ezihlanzekile kunenzuzo ngokusebenza okungcono nokuvumelana nezimo isikhathi eside.
