(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_GPUIndexedIndirectDrawCommand

A structure specifying the parameters of an indexed indirect draw command.

Header File

Syntax

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;

Remarks

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). If your shader depends on these variables, the correlating draw call parameter MUST be 0.

Version

This struct is available since SDL 3.1.3
