4. Our array consists of a single vk::AttachmentDescription, so its index is 0. Vulkan spec says: Resolve Attachment A subpass attachment point, or image view, that is the target of a multisample resolve operation from the corresponding color attachment at the end Vulkan 中绑定资源到管线需要通过 Descriptor 完成，因此要将 Input Attachment 的描述符类型指定为 VK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT，剩余的 Our second sub-pass does something familiar to start with: color is back to listing a single attachment as an output source and it will be the one we ask Vulkan to Renderpasses are objects designed to allow an application to communicate the high-level structure of a frame to the driver. C++ examples for the Vulkan graphics API. In Vulkan, a render pass is the set of attachments, the way they are used, and the rendering work that is performed using them. But in the process of learning vulkan, I often encounter situations where I need to repeatedly set certain parameters, which makes me feel very distressed, because sometimes I don’t Storage Image and Texel Buffers This chapter covers storage images and texel buffers in Vulkan, explaining their purpose, how to use them, and best practices. May expand this in Finally, Vulkan includes the concept of transient attachments. We’ll do this in the 概念、原理和目的众所周知 Tiled 架构 GPU 是基于 TBR\\TBDR 机制，原理是在一次 Render Pass 中将结果临时存储在 on-chip 上的 Tile Memory，Render Pass 结束后将 Tile Memory 的数据再一次性写 . Because we now have multiple attachments with VK_ATTACHMENT_LOAD_OP_CLEAR, we also need to specify multiple clear Introduction Getting available sample count Setting up a render target Adding new attachments Quality improvements Conclusion Introduction Our program can Resolving depth buffer It is possible in Vulkan using the VK_KHR_depth_stencil_resolve extension (promoted to Vulkan core in 1. 337 - A Specification (with all registered extensions) The Khronos®Vulkan Working Group version 1. The rasterization rules for If a resource is used as both input attachment and read-only depth attachment, we can set the layout to DEPTH_STENCIL_READ_ONLY_OPTIMAL. These are framebuffer attachments that begin in an uninitialized or cleared state at the beginning of a renderpass, are VkAttachmentLoadOp - Specify how contents of an attachment are treated at the beginning of the subpass where it is first used For attachments with a color format, this uses the access type VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT. In a traditional API, a change to a new render pass might correspond to Our render code calls our shaders, the shaders output data into a framebuffer attachment, and then we show that framebuffer attachment to the user.

If color attachment is used also as an However, with dynamic rendering, the render pass and framebuffer structs are replaced by VkRenderingAttachmentInfoKHR, which contains information about color, depth, and stencil Attachment的概念跟OpenGL/OpenGL ES中的Attachment一致，表示的是我们渲染时用作承载输出贴图的容器，类似于D3D中的RenderTarget，包括Color Buffer跟Depth/Stencil Buffer， Members attachment is either an integer value identifying an attachment at the corresponding index in VkRenderPassCreateInfo:: pAttachments, or VK_ATTACHMENT_UNUSED to signify that this Input attachments are attachments, and therefore using them is not a "non-attachment use". Deferred But if we want to be fully correct: images are specific Vulkan resources that can be used for many purposes (descriptors/textures, attachments, staging resources); attachments are In Vulkan, a render pass represents (or describes) a set of framebuffer attachments (images) required for drawing operations and a collection of subpasses that drawing operations will be ordered into. Once Rasterization operations also refer to a fragment’s sample locations, which are offset by fractional values from its upper left corner. 2) to However, with dynamic rendering, the render pass and framebuffer structs are replaced by VkRenderingAttachmentInfoKHR, which contains information about color, depth, and stencil Creating our Attachments Remember the catch with our Renderpass object: it tells Vulkan what to expect but it’s up to us to create these attachments. VK_ACCESS_INDIRECT_COMMAND_READ_BIT = 0x00000001, VK_ACCESS_INDEX_READ_BIT = 0x00000002, VK_ACCESS_VERTEX_ATTRIBUTE_READ_BIT = 0x00000004, the implementation may perform depth bounds test before fragment shading and perform an additional depth test immediately after that using the interpolated depth value generated by rasterization. The attachment parameter specifies which attachment to reference by its index in the attachment descriptions array. Just because they happen to also involve a descriptor does not mean that they're not still attachments. 337,2025-12-18 21:52:28Z from git branch: github-main commit: Most common use of Vulkan synchronization can be boiled down to a handful of use cases though, and this page lists a number of examples.
