Vulkan - draw a texture directly without vertices and shaders

Question

Is it possible to draw a texture (if it has the correct width, height and pixel format) directly in the frame buffer without using vertices and shaders in Vulkan?

Answer 1

You can do vkCmdCopyImageto copy from vkImageto swapchain vkImage, if vkSurfacesupported TRANSFER_DST, and the supportedUsageFlagsresult in the field vkGetPhysicalDeviceSurfaceCapabilitiesKHR.

Otherwise, you need to do full-screen rendering and capture color data from the input image as a selective texture or input.
