3D Graphics Rendering Cookbook
By :
Buffers in Vulkan are essentially memory regions that store data for GPU access. More specifically, a Vulkan buffer refers to a VkBuffer object that is associated with memory regions allocated through VkDeviceMemory. To render a 3D scene with Vulkan, we must convert the scene data into a format the GPU can process. In this recipe, we’ll explain how to create GPU buffers and upload vertex data into them. We’ll use the open-source asset-loading library Assimp https://github.com/assimp/assimp to load a 3D model from an .obj file and render it using LightweightVK and Vulkan. Additionally, this recipe includes a basic introduction to using the Vulkan Memory Allocator (VMA) library.
In Vulkan, uploading data to GPU buffers is done using command buffers, similar to many other Vulkan operations. This requires a command queue that supports transfer operations. The process of creating and using command buffers was covered in...
