I don't think there is any Rust (or any Rust on the roadmap) in Blender -- they would most likely use MoltenVK on macOS, similar to the path the Qt folks are ta

  I believe you can use this without touching Rust. If I remember correctly they even ran Dota2 with this. That certainly does not have Rust inside.
  • electricslpnsld 8y ago
    Interesting, thanks for the clarification! Any idea as to the advantages of using these bindings vs. the Molten bindings, if one isn't using Rust?
    • baobrien 8y ago
      I think -- and I could be wrong here -- that gfx-rs aims to eventually implement Vulkan on D3D12 in addition to Metal, while MoltenVK only aims to work on Metal.

        Are there any D3D12 platforms that don't also support Vulkan?
        • wolfgke 8y ago
          I am not completely sure, but I can imagine XBox One.
        • jsheard 8y ago
          Windows, partially. Vulkan can be used in classic win32 apps but not in "modern" UWP apps. The Xbox One uses a variant of D3D12 and doesn't support Vulkan at all.

            > Vulkan can be used in classic win32 apps but not in "modern" UWP apps. Why is this/how do they enforce that? The Xbox is hardly a surprise, but then again you're only going to target that for games so it's less of a problem.

              > Why is this/how do they enforce that? Technically Windows doesn't support Vulkan at all, but the openness of the win32 platform allowed Khronos to define a "backdoor" interface where the application ignores the Windows graphics stack and instead gets a Vulkan context by talking to the graphics driver directly. The UWP sandbox makes this impossible so you're stuck with the native Direct3D APIs.
              • drb91 8y ago
                Ahh, I had no idea UWP implied running on microsoft's terms. Is there a way to run them out of the sandbox manually?
                • megaman22 8y ago
                  Statistically, nobody actually builds real UWP apps, so it is largely an academic point. But if you're out of the sandbox, I fail to see a good reason not to just build a regular old Win32 app the way it has always been done.
                  • imtringued 8y ago
                    If you are on Windows on ARM then there is no option other than UWP apps. Why would anyone buy an ARM laptop if they have to rely on emulation for everything anyway. It's not like the ARM laptops are any cheaper than the intel ones. (they actually have worse specs and cost more)
        • johncolanduoni 8y ago
          Older Intel chips (pre-Skylake IIRC) don’t have Vulkan support on Windows, even though they do on Linux.
      • wlesieutre 8y ago
        I don't know about the MoltenVK branding specifically, but Khronos does plan a "Universally portable subset" of Vulkan with tools to target both Metal and D3D12 from one rendering codebase and common SPIR-V shaders. The project is call Vulkan Portability Initiative: https://www.khronos.org/blog/khronos-announces-the-vulkan-portability-initiative https://www.khronos.org/blog/khronos-announces-the-vulkan-po...
        • shmerl 8y ago
          If I understood correctly, gfx-rs aims to provide an implementation for that initiative. Khronos only announced it in concept, they didn't implement it.
        • kvark 8y ago
          Both gfx-rs and MoltenVK are in that technical subgroup within Khronos.
    • kvark 8y ago
      gfx-rs Metal backend can be powerful and faster
• steveklabnik 8y ago
  My understanding is that this exposes a C ABI so that it's not purely for Rust programs.
