检查 Vulkan 渲染状态
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
如需在提交特定命令后查看渲染状态，请点击命令窗格中的相应命令。在 State 窗格中，您可以使用以下各项检查渲染状态。
上次绑定队列（当前绑定的队列）
LastBoundQueue 节点包含用于提交相关命令的 vkQueueSubmit 的队列信息。VulkanHandle 将用于在 LastDrawInfos 中查找当前渲染状态的绘制信息。
VulkanHandle 会显示上次使用的 VkQueue 的值，该值实际上是所提交相关命令的当前绑定队列。
当前渲染状态的信息存储在 LastDrawInfos 中，并通过 VkQueue 值编入索引。
上次绘制信息（当前渲染状态信息）
LastDrawInfos 节点包含每个 VkQueue 的最后一个绘图的信息，包含以下信息：
- 帧缓冲区信息
- 渲染通道信息
- 绑定的描述符集
- 绑定顶点和索引缓冲区
- 图形管道
- 绘制参数
绑定帧缓冲区
Framebuffer 节点：显示当前绑定的帧缓冲区的信息。
在同一队列上执行每个 vkCmdBeginRenderPass 后，此节点会更新。
Renderpass 节点：显示用于创建帧缓冲区的渲染通道的信息。请注意，这不是当前用于绘制的渲染通道。
ImageAttachments 节点：列出绑定到帧缓冲区的所有图片附件 (VkImageViews)。列表中的每一项都会显示图片视图的信息。
Image 节点显示绑定到图片视图的图片信息。
绑定的 renderpass
Renderpass 节点：显示当前用于渲染的 renderpass 的信息。该函数会在每个 VkCmdBeginRenderPass 在同一队列上执行后更新。
AttachmentDescriptions 节点：列出当前正在使用的 renderpass 的所有 VkAttachmentDescription。
SubpassDescriptions 节点：列出每个子卡券的 VkSubpassDescription。
SubpassDependencies 节点：列出每个子卡券的 VkSubpassDependency。
绑定的描述符集
DescriptorSets 节点：列出当前绑定的所有描述符集。有边界描述符集的列表反映了最后一个 vkCmdBindDescriptorSets 在同一队列中发布之后的状态，并且原始描述符集信息将被覆盖，或者系统将根据上次执行的 vkCmdBindDescriptorSets 的参数添加新信息。
绑定：节点会列出描述符集中所有当前绑定的描述符绑定。
每个描述符绑定还会列出其绑定的描述符。
Layout 节点：显示用于分配描述符集的 VkDescriptorSetLayout 的信息。
绑定图形管道
GraphicsPipeline 节点：包含有关上次绑定图形管道的信息。在当前队列上执行每个 VkCmdBindPipeline 后，此节点都会更新。
绑定缓冲区
绘制命令参数
CommandParameters 节点：包含 vkCmdDraw、vkCmdDrawIndexed、vkCmdDrawIndirect 和 vkCmdDrawIndirectIndexed 的参数。对于每种类型的绘制命令，都有一个包含参数值的相应子节点。由于这四种绘制命令不能同时使用，因此一次只能填充四个子节点中的一个。在同一队列中执行四个绘制命令中的任意一个后，CommandParameters 的内容会更新。

The **State** pane lets\nyou examine the render state using the following items.\n\nLast bound queue (currently bound queue)\n----------------------------------------\n\nThe **LastBoundQueue** node contains the information of the queue used for the\n`vkQueueSubmit`, which submits the command in question. The `VulkanHandle` will\nbe used to find the drawing information of the current render state in\n`LastDrawInfos`.\n\n1. The `VulkanHandle` shows the value of the last used `VkQueue`, which is\n actually the currently bound queue for the submitted command in question.\n\n2. The information of the current render state is stored in `LastDrawInfos`,\n and indexed by the `VkQueue` value.\n\nLast draw infos (current render state info)\n-------------------------------------------\n\nThe **LastDrawInfos** node contains the information of the last drawing for each\n`VkQueue`, and includes the following information:\n\n- Framebuffer information\n- Render pass information\n- Bound descriptor sets\n- Bound vertex and index buffers\n- Graphics pipeline\n- Drawing parameters\n\n**Bound Framebuffer**\n\n- **Framebuffer** node: shows the info of the currently bound framebuffer.\n This node gets updated after each `vkCmdBeginRenderPass` executes on the\n same queue.\n\n- **Renderpass** node: shows the info of the render pass used to create the\n framebuffer. Note that this is not the render pass currently bound for\n drawing.\n\n- **ImageAttachments** node: lists all the image attachments (`VkImageViews`)\n bound to the framebuffer. Each item of the list shows the info of the image\n view.\n\n- **Image** node shows the info of the image bound to the image view.\n\n**Bound renderpass**\n\n- **Renderpass** node: shows the info of the renderpass currently used for rendering. It gets updated after each `VkCmdBeginRenderPass` executes on the same queue.\n\n- **AttachmentDescriptions** node: lists all the `VkAttachmentDescription` of the current renderpass in use.\n\n- **SubpassDescriptions** node: lists the `VkSubpassDescription` for each subpass.\n\n- **SubpassDependencies** node: lists the `VkSubpassDependency` for each subpass.\n\n**Bound descriptor sets**\n\n- **DescriptorSets** node: lists all the currently bound descriptor sets. The list of bounded descriptor sets reflect the state after the last `vkCmdBindDescriptorSets` being rolled out on the same queue, and the original descriptor set info will be overwritten or new info will be added according to the parameters of the last executed `vkCmdBindDescriptorSets`.\n\n- **Bindings**: node lists all the currently bound descriptor bindings in the\n descriptor set.\n\n Each descriptor binding also lists its bound descriptors.\n- **Layout** node: shows the info of the `VkDescriptorSetLayout` used to allocate the descriptor set.\n\n**Bound graphics pipeline**\n\n`GraphicsPipeline` node: contains the info about the last bound graphics pipeline. This node gets updated after each `VkCmdBindPipeline` executes on the current queue.\n\n**Bound Buffers**\n\n- **BoundVertexBuffers** node lists all the bound vertex buffers. For each bound vertex buffer, it shows the info of the backing buffer. The list gets updated accordingly after each `vkCmdBindVertexBuffers` executes on the same queue.\n\n- `BoundIndexBuffer` node shows the last bound index buffer, including the index type and the info of the backing buffer.\n\n**Draw Command Parameters**\n\n**CommandParameters** node: contains the parameters to `vkCmdDraw`, `vkCmdDrawIndexed`, `vkCmdDrawIndirect` and `vkCmdDrawIndirectIndexed`. For each type of drawing command, there is a corresponding sub-node to contains the parameter values. As these four types of drawining commands cannot be used at the same time, only one of the four sub-nodes can be populated at a time. The content of **CommandParameters** gets updated after any one of the four drawining commands being executed on the same queue."]]
