SDL_GPUMultisampleState(3type)

💖 SDL_GPUMultisampleState 💖

okay bestie, so this is a page from the SDL3 DATATYPES section of the manual, and it's all about SDL_GPUMultisampleState — a struct that specifies the parameters of the graphics pipeline multisample state. yes, that's a mouthful. yes, it's important. let's get into it 🦋

---

✨ NAME ✨

SDL_GPUMultisampleState — a structure specifying the parameters of the graphics pipeline multisample state. it's giving "I control how your pixels get sampled" and honestly? iconic 👑

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_gpu.h>

typedef struct SDL_GPUMultisampleState
{
    SDL_GPUSampleCount sample_count;  /**< The number of samples to be used in rasterization. */
    Uint32 sample_mask;               /**< Reserved for future use. Must be set to 0. */
    bool enable_mask;                 /**< Reserved for future use. Must be set to false. */
    bool enable_alpha_to_coverage;    /**< true enables the alpha-to-coverage feature. */
    Uint8 padding2;
    Uint8 padding3;
} SDL_GPUMultisampleState;

so we have six fields, and two of them are literally just vibing there as padding, which is so real of them 💅

• sample_count — an SDL_GPUSampleCount, aka the number of samples to be used in rasterization. this is the main character field fr fr ✨
• sample_mask — a Uint32 that is reserved for future use. must be set to 0. do not get creative with it, bestie, the future owns it 🔮
• enable_mask — a bool that is also reserved for future use. must be set to false. same energy, hands off 🚫
• enable_alpha_to_coverage — a bool, and true enables the alpha-to-coverage feature. this one you're actually allowed to touch 🫶
• padding2 — a Uint8. it's padding. it's doing its little padding job. let it cook 🙈
• padding3 — another Uint8. padding's bestie. matching set 🎀

ngl, when the docs say "reserved for future use", that is not a suggestion. set sample_mask to 0 and enable_mask to false, or you're gonna have a bad time 😭

🌈 AVAILABILITY 🌈

this struct is available since SDL 3.2.0. so if you're on anything older, it's not there, periodt ⭐

• SDL_GPUGraphicsPipelineCreateInfo(3type) — yeah, this is where your multisample state actually gets used. go read it, iykyk 💜

and that's the whole page, no cap!! go forth and multisample responsibly, bestie 🧚💖

this lil manual page came from Simple Directmedia Layer, SDL 3.4.18 — mwah, thanks for the docs, love u, bye 👑
