NAME
SDL_DrawGPUPrimitives - Draws data using bound graphics state.
HEADER FILE
Defined in SDL3/SDL_gpu.h
SYNOPSIS
#include "SDL3/SDL.h"
void SDL_DrawGPUPrimitives( SDL_GPURenderPass *render_pass, Uint32 num_vertices, Uint32 num_instances, Uint32 first_vertex, Uint32 first_instance);
DESCRIPTION
You must not call this function before binding a graphics pipeline.
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.
FUNCTION PARAMETERS
- render_pass
-
a render pass handle.
- num_vertices
-
the number of vertices to draw.
- num_instances
-
the number of instances that will be drawn.
- first_vertex
-
the index of the first vertex to draw.
- first_instance
-
the ID of the first instance to draw.
AVAILABILITY
This function is available since SDL 3.2.0.
