ʻO AMD i wehe ʻia i ka Radeon Rays 4.0 ray tracing technology

Ua haʻi mua mākouʻO ka AMD, ma hope o ka hoʻokuʻu hou ʻana o kāna polokalamu GPUOpen me nā mea hana hou a me kahi pānaʻi FidelityFX i hoʻonui ʻia, ua hoʻokuʻu pū i kahi mana hou o ka AMD ProRender renderer, me kahi Radeon Rays 4.0 ray tracing acceleration library (i ʻike mua ʻia ʻo FireRays).

Ma mua, hiki ke holo wale ʻo Radeon Rays ma OpenCL ma kahi CPU a i ʻole GPU, kahi palena koʻikoʻi. I kēia manawa ua hoʻokūpaʻa ʻia nā accelerators RDNA2 e hiki mai ana e hōʻike i nā ʻāpana ray tracing, Radeon Rays 4.0 i loaʻa i ka BVH optimizations i hoʻolālā ʻia no GPU, me ke kākoʻo no nā API haʻahaʻa: Microsoft DirectX 12, Khronos Vulkan, a me Apple Metal. I kēia manawa ua hoʻokumu ʻia ka ʻenehana ma HIP (Heterogeneous-Compute Interface for Portability) - ka AMD C++ parallel computing platform (e like me NVIDIA CUDA) - a ʻaʻole kākoʻo iā OpenCL.

ʻO ka mea hoʻonāukiuki loa, ua hoʻokuʻu ʻia ʻo Radeon Rays 4.0 me ka ʻole o ka wehe ʻana, ʻaʻole like me nā mana o ka ʻenehana. Ma hope o ka hoʻopiʻi ʻana mai kekahi mau mea hoʻohana, ua hoʻoholo ʻo AMD e hoʻohuli i kāna hoʻoholo. ʻO kēia kaʻu i kākau ai Luna Hoʻokele Huahana ProRender ʻO Brian Savery:

"Ua noʻonoʻo hou mākou i kēia pilikia i loko a e hana i kēia mau hoʻololi: E hoʻopuka ʻo AMD iā Radeon Rays 4.0 ma ke ʻano he open source, akā e waiho ʻia kekahi mau ʻenehana AMD i loko o nā hale waihona puke i hāʻawi ʻia i loko o ka SLA. E like me ka mea i hoikeia u/scotterkleman i ka pae e pili ana i ka demo weliweli o Unreal Engine 5, ua kūpaʻa mākou i ka hāʻawi ʻana i nā hale waihona puke ray tracing maʻamau i hoʻopaʻa ʻole ʻia i kahi mea kūʻai aku. ʻO ia ka manaʻo holoʻokoʻa o Radeon Rays, a ʻoiai ʻaʻole ia he manaʻo maikaʻi ʻole ka hāʻawi ʻana i nā hale waihona puke me ka laikini ʻae ʻia, e pili ana i kāu manaʻo, ua hoʻoholo mākou e hele i mua a wehe i ke kumu o ke code. No laila e ʻoluʻolu e hoʻomau i ke kūkulu ʻana i nā mea ʻoluʻolu me Radeon Rays, a inā ʻo ʻoe ke ʻano o ka mea hoʻomohala e makemake i ke komo ʻana i ke kumu kumu i kēia manawa, e hui pū me mākou ma o ka ʻaoʻao github a i ʻole GPUOpen. Nā kumu no Radeon Rays 2.0 loaʻa nō".

He nūhou maikaʻi kēia no ka poʻe makemake e hoʻohana i ka Radeon Rays, ʻoiai ʻo AMD ProRender i kēia manawa i loaʻa me ka luna a manuahi manuahi no Unreal Engine.
