SDL_DRAWGPUINDEXEDPRIMITIVESINDIRECT(3)

💖 SDL_DrawGPUIndexedPrimitivesIndirect — bestie edition 💖

okay so this is a page from the SDL3 FUNCTIONS manual (yes, those SDL3 functions, the GPU ones, we love her) and we're gonna talk about SDL_DrawGPUIndexedPrimitivesIndirect. sit down, grab a strawberry, this one's actually kinda iconic.

---

✨ NAME ✨

SDL_DrawGPUIndexedPrimitivesIndirect — draws data using bound graphics state with an index buffer enabled and with draw parameters set from a buffer. 💅

like… it draws. with indices. and the parameters come from a buffer instead of from you yelling numbers at the function directly. main character energy fr fr.

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_gpu.h>

void SDL_DrawGPUIndexedPrimitivesIndirect(
    SDL_GPURenderPass *render_pass,
    SDL_GPUBuffer *buffer,
    Uint32 offset,
    Uint32 draw_count);

not me showing up with the #include <SDL3/SDL_gpu.h> like it's a little invite to the function party 🎀

🦋 DESCRIPTION 🦋

okay so the tea: the buffer you pass in must consist of tightly-packed draw parameter sets, and each one of those sets has to match the layout of SDL_GPUIndexedIndirectDrawCommand. that's not optional, bestie, that's the whole vibe. 💖

and lowkey the most important part: you must not call this function before binding a graphics pipeline. like, do not. bind the pipeline first. no cap. 🙈

⚠️ seriously, pipeline first, function second. the order is the moment.

💜 FUNCTION PARAMETERS 💜

• render_pass — a render pass handle. she's the whole arena, the stage, the venue. 🎀
• buffer — a buffer containing draw parameters. the little box of numbers. ✨
• offset — the offset to start reading from the draw buffer. where you start scrolling, basically. 🦋
• draw_count — the number of draw parameter sets that should be read from the draw buffer. how many lil sets we're pulling out. 💅

---

⭐ AVAILABILITY ⭐

this function is available since SDL 3.2.0. so if you're on something older… bestie. update. 😭

---

and that's the whole page!! every flag, every parameter, every vibe, preserved. you're welcome. 🫶

kisses, from the Simple Directmedia Layer manual — SDL 3.4.18 — slay, periodt, go bind that pipeline 👑💖
