참여 매체(participating media)의 null-scattering PDF 계산에서 발생하던 0으로 나누기 오류를 수정했고, 최적화 코드를 오픈소스로 공개했다고 알림(관련 PR 링크 포함). pbrt-v4 저장소 관련 수정·성능 최적화 공개 소식입니다.

New Use Case Drop: IterX를 사용해 pbrt-v4의 CPU 핫스팟을 최적화했습니다. 광선당 불필요한 작업을 줄여 트래버설, 교차(intersection), 스펙트럼 연산, 볼류메트릭 샘플링 등 물리 기반 렌더링의 핵심 병목을 해결했으며, AMD EPYC 환경에서 성능 향상을 확인한 실사용 최적화 사례를 제시합니다.

🧑🍳New Use Case Drop! 🧐We used IterX to optimize pbrt-v4’s hottest CPU paths, tackling a core bottleneck in physically based rendering: the cost of doing more work per ray than necessary during traversal, intersection, spectrum math, and volumetric sampling. 🥳On an AMD EPYC
VertexwahnThere is now a FOSS version of my Okapi ray tracer - you can clone it from https://github.com/Vertexwahn/OkapiRT. It uses Bazel as build system. Was inspired Pbrt, Nori, Mitsuba, Luisa Compute #bazel #raytracing #3d #cpp #pbrt

Read and write PFM and OpenEXR HDR images.
I'll be using this package for 3d rendering with #pbrt

Re-voxelizing the bunny.
I've tweaked the code to drop duplicate voxels. This avoids multiple voxels at the same location z-fighting for display and causing artefacts.
This render is for @JensWiesehahn's eagle eyes!
