SDL_GPUVertexBufferDescription3type
A structure specifying the parameters of vertex buffers used in a graphics pipeline.
Usage
#include "SDL3/SDL.h"
typedef struct SDL_GPUVertexBufferDescription { Uint32 slot; /**< The binding slot of the vertex buffer. */ Uint32 pitch; /**< The byte pitch between consecutive elements of the vertex buffer. */ SDL_GPUVertexInputRate input_rate; /**< Whether attribute addressing is a function of the vertex index or instance index. */ Uint32 instance_step_rate; /**< Reserved for future use. Must be set to 0. */ } SDL_GPUVertexBufferDescription;

Overview
When you call SDL_BindGPUVertexBuffers , you specify the binding slots of the vertex buffers. For example if you called
SDL_BindGPUVertexBuffers
with a first_slot of 2 and num_bindings of 3, the binding slots 2, 3, 4 would be used by the vertex buffers you pass in.
Vertex attributes are linked to buffers via the buffer_slot field of
SDL_GPUVertexAttribute . For example, if an attribute has a buffer_slot of 0, then that attribute belongs to the vertex buffer bound at slot 0.
