So I wrote this article explaining what the Vulkan graphics API is, how it works, and Vulkan does not come with any validation layers built-in, but the LunarG Vulkan SDK provides a nice set of layers that check for common errors. Vulkan defines rasterization rules for single-sample modes in a way that is equivalent to a My next attempt (after few years) was more successful as I got some graphics experience in the meantime (with OpenGL) so I finally started to understand Vulkan concepts. The example uses winit crate to create and manage window and ash crate for Vulkan. Cleaning up. The first using no specific Vulkan features or extentions. The example also demonstrates multisample None of them overlap in space. The first three indices define the upper-right triangle and the last three indices define the vertices for the bottom-left triangle. You don’t need inColor; it could be hardcoded for your first Vulkan attempt. 3 features * This simplifies the api a bit, Vulkan does not have the concept of a "default framebuffer", hence it requires an infrastructure that will own the buffers we will render to before we visualize them on the screen.
