💖 SDL_GenerateMipmapsForGPUTexture 💖

okay bestie come SIT with me because we're in the SDL3 FUNCTIONS section of the manual and this one is genuinely so satisfying ✨ it's giving "one line of code, whole pyramid of pixels" and I'm obsessed 🦋

✨ NAME ✨

SDL_GenerateMipmapsForGPUTexture — generates mipmaps for the given texture, fr fr 🎀

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_gpu.h>

void SDL_GenerateMipmapsForGPUTexture(
    SDL_GPUCommandBuffer *command_buffer,
    SDL_GPUTexture *texture);

look at her 💅 void return, two args, no drama. iconic.

💫 DESCRIPTION 💫

so like, this function generates mipmaps for the texture you hand it. that's it, that's the whole vibe. it does the whole downsample-y mip chain thing for you so you don't have to sit there manually making smaller and smaller versions like some kind of Victorian orphan 😭

⚠️ no cap, this is the important part: this function must not be called inside of any pass. like, any pass. not a render pass, not a compute pass, not a copy pass, none of them. it's a between-passes kind of girl 🚫🎀

---

🫶 FUNCTION PARAMETERS 🫶

• command_buffer — a command_buffer 💜 the little vessel that carries your command to the GPU, bestie. she's just the messenger.
• texture — a texture with more than 1 mip level 🌈 read that again: more than 1 mip level. if your texture only has one mip level there is literally nothing to generate and this whole situation is a no 💀

---

⭐ AVAILABILITY ⭐

this one has been serving since SDL 3.2.0 — so if you're on anything older, sorry babe, no mipmaps for you 🙈

and that's the whole page!! go forth and generate those mips, you absolute main character 👑
