vpTracePixel(3)

🦋 NAME 🦋

vpTracePixel — ok so it literally prints a trace of the voxels composited into a pixel 💅

✨ SYNOPSIS ✨

#include <volpack.h>

vpResult
vpTracePixel(vpc, trace_u, trace_v)
    vpContext *vpc;
    int trace_u, trace_v;

🎀 ARGUMENTS 🎀

• vpc — your VolPack context, the one you got from vpCreateContext. You know her, you made her. 🫶
• trace_u, trace_v — the intermediate image coordinates of the pixel you wanna trace, bestie. Like, which pixel. Those two numbers. 👑

🔥 DESCRIPTION 🔥

So this routine is for debugging the rendering algorithms. It's giving "dev tools, not glamour" but honestly? Kinda iconic. 🙈

If (trace_u, trace_v) is a valid set of coordinates in the intermediate image, then a printout appears during rendering showing a trace of all of the voxels that contribute to the pixel. Every single one. Not me getting the full receipts on a pixel. 💀✨

⚠️ Heads up though — the intermediate image is not the same as the final image. Do not confuse them, bestie. See vpGetvpSetImage(3) for the lore. 📖

And the big one, the part you cannot skip: the VolPack library must be compiled with the -DDEBUG compiler option for this function to have any effect. No -DDEBUG, no trace. That's it. That's the vibe check. 🚨
