SDL_GPUFrontFace(3type)

✨ SDL_GPUFrontFace ✨

okay bestie, welcome to the SDL_GPUFrontFace page 💖 this is one of those little SDL3 datatypes, and honestly? it's giving "small but mighty." it lives in the SDL3 DATATYPES corner of the manual and it's here to answer one very specific, very important question: which way is your triangle facing?? 🦋

---

🌸 NAME 🌸

SDL_GPUFrontFace — Specifies the vertex winding that will cause a triangle to be determined to be front-facing.

like. that's the whole vibe. it tells you which direction the vertices are winding around when a triangle counts as front-facing 👑 no cap.

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_gpu.h>

typedef enum SDL_GPUFrontFace
{
    SDL_GPU_FRONTFACE_COUNTER_CLOCKWISE,  /**< A triangle with counter-clockwise vertex winding will be considered front-facing. */
    SDL_GPU_FRONTFACE_CLOCKWISE           /**< A triangle with clockwise vertex winding will be considered front-facing. */
} SDL_GPUFrontFace;

so we got exactly two options in this enum, and they are:

• SDL_GPU_FRONTFACE_COUNTER_CLOCKWISE — A triangle with counter-clockwise vertex winding will be considered front-facing. 🔄
• SDL_GPU_FRONTFACE_CLOCKWISE — A triangle with clockwise vertex winding will be considered front-facing. 🔁

pick your fighter. the vertices are literally just going around in a circle and you're deciding which direction counts as "hey, this one's facing the camera." iconic behavior tbh 💅

🎀 AVAILABILITY 🎀

This enum is available since SDL 3.2.0. periodt. if you're on anything older, it's not gonna be there for you, bestie 😭

🫶 SEE ALSO 🫶

• SDL_CreateGPUGraphicsPipeline(3)

go check that one out if you wanna actually, like, use this enum in a graphics pipeline. iykyk 🌈

ngl this enum is lowkey the main character of backface culling. front-facing vs back-facing? that's all decided right here. no cap. 💀

and that's the whole page, bestie!! this was the SDL_GPUFrontFace datatype page from the Simple Directmedia Layer crew, sitting pretty at SDL 3.4.18, dated like the rest of the SDL 3 docs ✨ slay, go render some triangles, and remember: winding order matters. mwah 💖🎀🦋
