Using Vulkan command buffers

In the previous recipes, we learned how to create a Vulkan instance, a device for rendering, and a swap chain object with images and image views. In this recipe, we will learn how to fill command buffers and submit them using queues, which will bring us a bit closer to rendering our first image with Vulkan.

How to do it...

Let's prepare a command buffer that will begin a new render pass, clear the color and depth attachments, bind pipelines and descriptor sets, and render a mesh:

1. First, we need to fill in a structure describing a command buffer:

   bool fillCommandBuffers(size_t i) {
     const VkCommandBufferBeginInfo bi = {    .sType =       VK_STRUCTURE_TYPE_COMMAND_BUFFER_BEGIN_INFO,    .pNext = nullptr,    .flags =      VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT,    .pInheritanceInfo = nullptr...
