SDL_GPUIndexedIndirectDrawCommand.3type - Man Page

Defined in SDL3/SDL_gpu.h

#include "SDL3/SDL.h"

typedef struct SDL_GPUIndexedIndirectDrawCommand
{
    Uint32 num_indices;    /**< The number of indices to draw per instance. */
    Uint32 num_instances;  /**< The number of instances to draw. */
    Uint32 first_index;    /**< The base index within the index buffer. */
    Sint32 vertex_offset;  /**< The value added to the vertex index before indexing into the vertex buffer. */
    Uint32 first_instance; /**< The ID of the first instance to draw. */
} SDL_GPUIndexedIndirectDrawCommand;

Note that the first_vertex and first_instance parameters are NOT compatible with built-in vertex/instance ID variables in shaders (for example, SV_VertexID); GPU APIs and shader languages do not define these built-in variables consistently, so if your shader depends on them, the only way to keep behavior consistent and portable is to always pass 0 for the correlating parameter in the draw calls.

This struct is available since SDL 3.2.0.
