RenderPass RenderPass is a new concept proposed by modern graphics API. Simply put, RenderPass is an execution of the entire Render Pipeline. The essence of RenderPass is to define a complete rendering process and a description of all resources used. It can be understood as a metadata or placeholder concept that does not contain any […]

Vulkan memory model + management
Foreword Recently, I am studying Vulkan. Using memory in Vulkan is a troublesome process, and it is easy to use it wrong. Today I will share with you the memory model of Vulkan. Memory is a scarce resource at any time, and memory management is even more daunting. In today’s advocating user experience, both the […]
Vulkan Tutorial 9 Model Loading & Mipmaps
Directory 28 Load the model Sample mesh load vertices and indices ?edit Vertex deduplication 29 Generating Mipmaps create image Generate Mipmaps Supports linear filtering Sampler 28 Load model We will use the tinyobjloader library to load vertices and faces from OBJ files. It’s fast and easy to integrate since it’s a single-file library like stb_image. […]

Directory 5 window surface 6 swap chain 7 Image View 5 window surface Since Vulkan is a platform-independent API, it cannot interface directly with the window system itself. In order to create a connection between Vulkan and the windowing system to display the results on the screen, we need to use the WSI (Windowing System […]
