Preparing a single frame of animation

Usually, when we create 3D applications that render images, we would like images to be displayed on screen. For this purpose, a swapchain object is created in Vulkan. We know how to acquire images from a swapchain. We have also learned how to present them. Here, we will see how to connect image acquiring and presentation, how to record a command buffer in between, and how we should synchronize all of these operations to render a single frame of animation.

How to do it...

1. Take the handle of a logical device and store it in a variable of type VkDevice named logical_device.
2. Use a handle of a created swapchain to initialize a variable of type VkSwapchainKHR named swapchain.
3. Prepare a semaphore handle in a variable of type VkSemaphore named image_acquired_semaphore. Make sure the semaphore is unsignaled or isn't being used in any previous submissions that haven't completed yet.

 

4. Create a variable of type uint32_t named image_index.
5. Acquire an image from the swapchain...
