vpSetVolumeSize(3)

✨ vpSetVolumeSize ✨

okay so bestie, welcome to the vpSetVolumeSize(3) page from the Library Functions Manual 💖 this is the lil function that tells VolPack how big your volume actually is. it's giving "set the vibe, then load the data." no cap.

---

🌸 SYNOPSIS 🌸

#include <volpack.h>

vpResult
vpSetVolumeSize(vpc, xlen, ylen, zlen)
    vpContext *vpc;
    int xlen, ylen, zlen;

---

🎀 ARGUMENTS 🎀

• vpc — the VolPack context you got from vpCreateContext. your main character struct 🫶
• xlen — how big the first dimension of the volume is, measured in voxels.
• ylen — how big the second dimension of the volume is, in voxels.
• zlen — how big the third dimension of the volume is, in voxels.

---

🦋 DESCRIPTION 🦋

so like, vpSetVolumeSize is literally just here to define the dimensions of a volume. that's it, that's the job. 💅

it must be called before volume data gets loaded into a rendering context. like, before. not after. the order is not optional, bestie, it's the whole point.

⚠️ also heads up: any existing precomputed volume data structures chilling in the context get destroyed. gone. poof. so don't call this casually unless you're ready to say goodbye 😭

---

⭐ STATE VARIABLES ⭐

you can peek at the current volume dimensions with these state variable codes (check vpGeti(3) for the deets): VP_XLEN, VP_YLEN, VP_ZLEN. iykyk 🌈

---

💀 ERRORS 💀

the return value is always VP_OK. always. every single time. iconic behaviour honestly 👑
