NAME¶

SDL_GPUVertexBufferDescription - A structure specifying the parameters of vertex buffers used in a graphics pipeline.

SYNOPSIS¶

#include <SDL3/SDL_gpu.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;

DESCRIPTION¶

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.

AVAILABILITY¶

This struct is available since SDL 3.2.0.
