rtcGetGeo...ufferData(3)

💖 rtcGetGeometryBufferData — Embree Ray Tracing Kernels 3, section 3 💖

okay bestie, so you're deep in the Embree 3 ray tracing kernels and you need to find where your geometry's buffer data actually lives in memory?? this one's for you, it's giving pointer-retrieval realness ✨

🌸 NAME 🌸

rtcGetGeometryBufferData — gets pointer to the first buffer view element 🫶

✨ SYNOPSIS ✨

#include <embree3/rtcore.h>

void* rtcGetGeometryBufferData(
  RTCGeometry geometry,
  enum RTCBufferType type,
  unsigned int slot
);

🦋 DESCRIPTION 🦋

so the rtcGetGeometryBufferData function hands you back a pointer to the very first element of the buffer view that's attached to the buffer type and slot you asked for (that's the type and slot arguments, bestie 👀) on the geometry you passed in (yep, the geometry argument).

like, it's not a copy, it's not a new allocation, it's just here's the address, go wild 💅 first element, that's the vibe. 🎀

💀 EXIT STATUS 💀

if it doesn't go well, an error code gets set — and you can go check on it with rtcGetDeviceError. so if something's feeling off, that's where the receipts are, fr fr 😭
