vpSetMatrix(3)

💖 vpSetMatrix — bestie edition 💖

okay so this is a page from the VolPack library functions manual, and today we're talking about vpSetMatrix(3), which is genuinely one of the most straightforward little guys in the whole API. no cap. she just loads a matrix. that's the whole job. slay.

✨ NAME ✨

vpSetMatrix — load a matrix into the current transformation matrix 💅

🦋 SYNOPSIS 🦋

#include <volpack.h>

vpResult
vpSetMatrix(vpc, m)
    vpContext *vpc;
    vpMatrix4 m;

🎀 ARGUMENTS 🎀

• vpc — the VolPack context, bestie. you get one of these from vpCreateContext. it's like the group chat; everything happens inside it 🫶
• m — the input matrix. this is the thing you're loading. she's the main character of this function fr fr.

🌸 DESCRIPTION 🌸

okay so here's the tea: vpSetMatrix is the function you call when you wanna load a 4-by-4 transformation matrix into the current transformation matrix. that's it. that's the vibe. you hand her a matrix, she puts it where the current transformation matrix lives. iconic behavior honestly.

but wait — which matrix is the current one? that's not this function's problem, bestie 😭. to actually set the current transformation matrix you use vpCurrentMatrix. vpSetMatrix is the one that does the loading, vpCurrentMatrix is the one that decides what "current" even means. they're a duo. a little duo. obsessed with them.

⭐ STATE VARIABLES ⭐

you can pull the current transformation matrix parameters back out with these state variable codes — go peek at vpGeti(3) for the deets:

• VP_CURRENT_MATRIX

💀 ERRORS 💀

the return value is always VP_OK. always. every single time. no drama, no error codes, no surprises. it's giving emotionally stable. 🙈
