✨ RTCCurveFlags πŸ’… β€” the manual page, bestie edition πŸŽ€

okay so you're here for RTCCurveFlags(3) from the Embree Ray Tracing Kernels 3 era? perfect, sit down, hydrate, we're doing curves today πŸ¦‹


🌸 NAME 🌸

RTCCurveFlags β€” per segment flags for curve geometry ✨ (yes, per segment, not per curve, we love a granular queen πŸ‘‘)


πŸ’– SYNOPSIS πŸ’–

#include <embree3/rtcore.h>

enum RTCCurveFlags { RTC_CURVE_FLAG_NEIGHBOR_LEFT = (1 << 0),
RTC_CURVE_FLAG_NEIGHBOR_RIGHT = (1 << 1) };

that's it. two flags. iconic minimalism. 🫢


🌈 DESCRIPTION 🌈

so the RTCCurveFlags type exists for linear curves β€” it's how you tell Embree whether the left neighbor segment and/or the right neighbor segment actually exist. πŸ’«

the way you do that: you attach a buffer of type RTC_BUFFER_TYPE_FLAGS to the curve geometry, and that buffer stores an individual byte per curve segment. one byte, one segment, no cap 🧚

  • if the RTC_CURVE_FLAG_NEIGHBOR_LEFT flag is enabled in that byte for a curve segment β†’ the left segment exists (it's the one that starts one vertex before the start vertex of the current curve), and the current segment gets rendered so it properly attaches to that segment. πŸ’–
  • if the RTC_CURVE_FLAG_NEIGHBOR_RIGHT flag is enabled in that byte for a curve segment β†’ the right segment exists (it's the one that ends one vertex after the end vertex of the current curve), and the current segment gets rendered so it properly attaches to that segment. ✨
⚠️ and like… if you don't properly specify the left and right flags for linear curves, the rendering at the endings of those curves may not look correct. especially when round linear curves are viewed from the inside. that's the vibes check failing, bestie 😭 please set your flags.

and that's the whole page!! πŸŽ€ this was RTCCurveFlags(3), straight out of the Embree Ray Tracing Kernels 3 docs (the footer of the original was just the title RTCCurveFlags(3) again β€” no date printed, so consider this your undated, timeless, slay little sign-off). go set those neighbor flags, bestie, your curves will thank you πŸ’…βœ¨πŸŒΈ
