Ending a render pass

When all commands from all subpasses are already recorded, we need to end (stop or finish) a render pass.

How to do it...

1. Take the handle of a command buffer and store it in a variable of type VkCommandBuffer named command_buffer. Make sure the command buffer is in a recording state and that the operation of beginning a render pass was already recorded in it.
2. Call vkCmdEndRenderPass( command_buffer ) for which provide the command_buffer variable.

How it works...

To end a render pass, we need to call a single function:

vkCmdEndRenderPass( command_buffer );

Recording this function in a command buffer performs multiple operations. Execution and memory dependencies are introduced (like the ones in memory barriers) and image layout transitions are performed--images are transitioned from layouts specified for the last subpass to the value of a final layout (refer to the Specifying attachment descriptions recipe). Also multisample resolving is performed on color attachments for which...
