Creating framebuffers

While the render pass object contains information about what to do with each attachment and their initial and final layouts, a framebuffer contains actual references to the attachments used in the render pass, which are provided in the form of VkImageViews.

In this recipe, you will learn how to create a framebuffer object.

Getting ready

In the repository, Vulkan framebuffers are encapsulated by the VulkanCore::Framebuffer class.

How to do it…

Framebuffers refer to attachments (it answers the question “Which attachments will we be using for this render pass?”).

1. The references are image views and are passed as a list, along with the handle of the render pass, to the vkCreateFramebuffer framebuffer creation function:

   uint32_t width, height; // Width and height of attachments
   VkDevice device; // Valid Vulkan Device
   std::vector<VkImageView> imageViews; // Valid Image Views
   const VkFramebufferCreateInfo framebufferInfo...
