During command buffer recording:
VK_KHR_create_renderpass2 provides an enhanced version of the original render pass creation mechanism ( vkCreateRenderPass ). It introduces new structures and entry points that allow applications to specify more detailed information about subpass dependencies, attachment references, and—crucially—fragment density maps and fragment shader interlock features. vk-khr-create-renderpass-2-extension-name
Here’s a technical write-up on the extension, focusing on its purpose, key features, and why it replaces the original vkCreateRenderPass . VK_KHR_create_renderpass2 – Write-Up Overview Extension Name: VK_KHR_create_renderpass2 Date of Promotion: 2018 (originally an extension, later promoted to Vulkan 1.2 core) Dependencies: Vulkan 1.0, VK_KHR_get_physical_device_properties2 (for some features) Associated Core Version: Vulkan 1.2 (functionality included as core) const VkRenderPassCreateInfo2KHR* pCreateInfo
VkResult vkCreateRenderPass2KHR( VkDevice device, const VkRenderPassCreateInfo2KHR* pCreateInfo, const VkAllocationCallbacks* pAllocator, VkRenderPass* pRenderPass ); void vkCmdBeginRenderPass2KHR( VkCommandBuffer commandBuffer, const VkRenderPassBeginInfo* pRenderPassBegin, const VkSubpassBeginInfoKHR* pSubpassBeginInfo ); const VkAllocationCallbacks* pAllocator
vkCreateRenderPass2KHR(device, &rpInfo, nullptr, &renderPass);
If you are writing a Vulkan renderer today, the version 2 render pass functions unless you are strictly maintaining a legacy codebase.

"Members on this website are “retired” FBI agents, many who are “licensed” Private Investigators [PIs], independent contractors and vendors who promote and sell their services as consultants to members of the public, public and/or private industry and/or local, state and/or federal government.
As consultants, they “contract” out their services to conduct criminal/civil investigations, provide litigation support, conduct due diligence inquires, provide executive protection and conduct background screenings, offer expert opinions concerning investigations, do electronic sweeps and counter measures, provide drug screenings, offer forensic accounting services, and conduct surveillances, as well as locate assets and/or conduct other research.
As a result, members command fees for their services. This is “not” a free service.
Before any services will be expended, most members will require a “nonrefundable” retainer fee totaling $1500 - $2500. The amount of the retainer fee will be set by members during contract negotiations. And some members command “nonrefundable” retainer fees totaling $5000.
Unless you are a journalist looking for media “commentary,” and/or someone with an offer of employment, please be advised members do not provide “free” services but will require a retainer fee before any services will be expended. These services are “not” free.
