SDL_DrawGPUPrimitives - Draws data using bound graphics state.
Contents
Availability
This function is available since SDL 3.2.0.
Simple Directmedia Layer SDL 3.2.20 SDL_DrawGPUPrimitives(3)
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.
