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

SDL_GPUIndirectDrawCommand

A structure specifying the parameters of an indirect draw command.

Header File

Syntax

typedef struct SDL_GPUIndirectDrawCommand
{
    Uint32 num_vertices;   /**< The number of vertices to draw. */
    Uint32 num_instances;  /**< The number of instances to draw. */
    Uint32 first_vertex;   /**< The index of the first vertex to draw. */
    Uint32 first_instance; /**< The ID of the first instance to draw. */
} SDL_GPUIndirectDrawCommand;

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
