Introduction This short tutorial deals with Vulkan’s viewport setup, which differs from the one in OpenGL and other APIs. I’ll try to explain what it takes to get your (OpenGL) scene rendered properly, and how e.g. VK_KHR_MAINTENANCE1 can help you deal with differences across the APIs, something that’s esp. helpful if you try to add Vulkan as a backend to you renderer without wanting to alter your actual scene data.
