SDL_GPUIndirectDrawCommand Struct Reference

#include <SDL_gpu.h>

Data Fields

Uint32 num_vertices
 
Uint32 num_instances
 
Uint32 first_vertex
 
Uint32 first_instance
 

Detailed Description

A structure specifying the parameters of an indirect draw command.

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.

Since
This struct is available since SDL 3.2.0.
