S3D_PEP_LINE_NORMALS(3)

✨ S3D_PEP_LINE_NORMALS ✨

okay so bestie, welcome to the s3d manual, section 3 🎀 — today's main character is s3d_pep_line_normals, and she's literally the glow-up your lines have been begging for 💅

🌸 NAME 🌸

s3d_pep_line_normals — add normals to lines 🦋

⭐ SYNOPSIS ⭐

#include <s3d.h>

int s3d_pep_line_normals(int object, const float *nbuf, uint16_t n);

💖 DESCRIPTION 💖

So what she does is: she adds normal information to lines, giving every single vertex of a line its own normal info. And like… it makes lines somewhat nicer?? Yes. Lowkey a whole vibe upgrade. You'll especially need this when you're out here building wireframe models — that's the moment it really eats 🔥

Now the important part, no cap: nbuf should contain n * 6 float values. Why six? Because for each vertex you give a normal vector (x,y,z) — that's three floats — and you've got 2 vertices for each line, so that's 6 float values per line in total. Math girlie behavior, we love to see it 💀✨
